Taveuni (pronounced [tāhvéuni] ) is the third-largest island in Fiji , after Viti Levu and Vanua Levu , with a total land area of 434 square kilometres (168 square miles). The cigar-shaped island, a massive shield volcano which rises from the floor of the Pacific Ocean , is situated 6.5 kilometres (4.0 miles) east of Vanua Levu, across the Somosomo Strait . It belongs to the Vanua Levu Group of islands and is part of Fiji's Cakaudrove Province within the Northern Division .

91-489: The Somosomo Strait is the strait that separates Taveuni island and Vanua Levu in Fiji . It is known for its soft coral and is a popular diving location. This article about a geographical location in Fiji is a stub . You can help Misplaced Pages by expanding it . Taveuni The island had a population of around 19,000, some 75 per cent of them indigenous Fijians , at the 2015 census. Taveuni has abundant flora and

182-474: A lava flow at the southern tip of the island around 1550. The island's central ridge delineates the greatest volcanic activity surrounding volcanic vents. Lake Tagimaucia is one of Taveuni's most famous tourist attractions. It occupies a volcanic crater at an altitude of 800 metres (2,600 feet), and is the habitat of the rare tagimaucia flower. Fiji's most famous waterfalls , the Bouma Falls , are also on

273-637: A lek mating system. Another possibility is that songs bring in foreign whales to populate the breeding grounds. It has also been suggested that humpback whale songs have echolocating properties and may serve to locate other whales. A 2023 study found that as humpback whales numbers have recovered from whaling, singing has become less common. Whale songs are similar among males in a specific area. Males may alter their songs over time, and others in contact with them copy these changes. They have been shown in some cases to spread "horizontally" between neighboring populations throughout successive breeding seasons. In

364-433: A "spillover" of mobbing behavior intended to protect members of its species. The powerful flippers of humpback whales, often infested with large, sharp barnacles , are formidable weapons against orcas. When threatened, they will thresh their flippers and tails keeping the orcas at bay. The great white shark is another confirmed predator of the humpback whale. In 2020, Marine biologists Dines and Gennari et al. , published

The Taveuni dialect of Fijian reflects Tongan influence. One of its most distinctive features is the replacement of the consonant 'k' by a glottal stop . The Tui Cakau is therefore known locally as the Tui Ca'au. Taveuni notable peoples of high birth, other settler societies or ordinary Fijian (Indigenous) residents can be traced back to

546-435: A documented incident of a group of great white sharks exhibiting pack-like behavior to attack and kill a live adult humpback whale. A second incident regarding great white sharks killing humpback whales was documented off the coast of South Africa. The shark recorded instigating the attack was a female nicknamed "Helen". Working alone, the shark attacked a 33 ft (10 m) emaciated and entangled humpback whale by attacking

637-402: A laryngeal sac. Humpback whale groups, aside from mothers and calves, typically last for days or weeks at the most. They are normally sighted in small groups though large aggregations form during feeding and among males competing for females. Humpbacks may interact with other cetacean species, such as right whales , fin whales , and bottlenose dolphins . Humpbacks are highly active at

728-439: A number of nursing stations and health centres are located around the island. Other settlements include Bouma, Deleni, Gacaavulu, Kanacea, Korovou, Lavena, Matei, Naselesele, Navakawau, Salialevu, Soqulu, Vuna, Wairiki, and Welagi. The climate of Taveuni and Fiji is tropical without temperate extremes. It has been described as typical highland . Between November and April, the area is prone to tropical cyclones. Rainfall rates on

819-569: A phrase. Similar-sounding phrases are repeated in a series grouped into themes, and multiple themes create a song. The function of these songs has been debated, but they may have multiple purposes. There is little evidence to suggest that songs establish dominance among males. However, there have been observations of non-singing males disrupting singers, possibly in aggression. Those who join singers are males who were not previously singing. Females do not appear to approach singers that are alone, but may be drawn to gatherings of singing males, much like

910-415: A touring exhibition that traveled to Edinburgh and London . The whale was dissected by Professor John Struthers , who wrote seven papers on its anatomy and an 1889 monograph on the humpback. An albino humpback whale that travels up and down the east coast of Australia became famous in local media because of its rare, all-white appearance. Migaloo is the only known Australian all-white specimen, and

1001-426: A weight of 680 kg (1,500 lb). The body is bulky with a thin rostrum and proportionally long flippers, each around one-third of its body length. It has a short dorsal fin that varies from nearly non-existent to somewhat long and curved. As a rorqual, the humpback has grooves between the tip of the lower jaw and the navel. They are relatively few in number in this species, ranging from 14 to 35. The mouth

There is some evidence for a fifth population somewhere in the northwestern Pacific. These whales are recorded to feed off the Aleutians with a breeding area somewhere south of the Bonin Islands . In the Southern Hemisphere, humpback whales are divided into seven breeding stocks, some of which are further divided into sub-structures. These include

1183-445: Is an accepted version of this page The humpback whale ( Megaptera novaeangliae ) is a species of baleen whale . It is a rorqual (a member of the family Balaenopteridae ) and is the only species in the genus Megaptera . Adults range in length from 14–17 m (46–56 ft) and weigh up to 40 metric tons (44 short tons). The humpback has a distinctive body shape, with long pectoral fins and tubercles on its head. It

1274-549: Is at 81°N around northern Franz Josef Land . They are usually coastal and tend to congregate in waters within continental shelves . Their winter breeding grounds are located around the equator; their summer feeding areas are found in colder waters, including near the polar ice caps. Humpbacks go on vast migrations between their feeding and breeding areas, often crossing the open ocean. The species has been recorded traveling up to 8,000 km (5,000 mi) in one direction. An isolated, non-migratory population feeds and breeds in

1365-752: Is considered to be endangered . In most areas, humpback whale populations have recovered from historic whaling, particularly in the North Pacific. Such recoveries have led to the downlisting of the species' threatened status in the United States, Canada, and Australia. In Costa Rica, Ballena Marine National Park was established for humpback protection. Humpbacks still face various other man-made threats, including entanglement by fishing gear, vessel collisions, human-caused noise and traffic disturbance, coastal habitat destruction, and climate change. Like other cetaceans, humpbacks can be injured by excessive noise. In

1456-554: Is found only on Taveuni. It was discovered by scientists in 1977. The flowering plant Balaka seemannii , which is endemic to Fiji, is found on the island. The green iguana or American iguana has been introduced to the Fijian islands. The lizard poses a threat because it has no natural enemies, can reach a high population density, eats the taro plant and because it carries Salmonella bacteria which can be transferred to humans if bitten. In 2013, an eradication program coordinated by

1547-545: Is further divided into C1, C2, C3, and C4 subpopulations; C1 occurs around Mozambique and eastern South Africa, C2 around the Comoro Islands , C3 off the southern and eastern coast of Madagascar and C4 around the Mascarene Islands . The feeding range of this population is likely between coordinates 5°W and 60°E and under 50°S . There may be overlap in the feeding areas of stocks B and C. Stock D whales breed off

1638-408: Is known as the 'Garden Island of Fiji'. It is a popular tourist destination. Tourists are attracted by the excellent diving opportunities, prolific bird life, bushwalks and waterfalls. Central parts of the island receive very high rainfall. Being volcanic in origin, Taveuni's soils have supported the island's most historically significant industry, agriculture. Taveuni is located at the northern end of

1729-591: Is known for breaching and other distinctive surface behaviors , making it popular with whale watchers . Males produce a complex song typically lasting 4 to 33 minutes. Found in oceans and seas around the world, humpback whales typically migrate up to 16,000 km (9,900 mi) each year. They feed in polar waters and migrate to tropical or subtropical waters to breed and give birth. Their diet consists mostly of krill and small fish , and they use bubbles to catch prey. They are promiscuous breeders, with both sexes having multiple partners. Orcas are

1820-449: Is lined with baleen plates, which number 270–400 for both sides. The dorsal or upper-side of the animal is generally black; the ventral or underside has various levels of black and white coloration. Whales in the southern hemisphere tend to have more white pigmentation. The flippers can vary from all-white to white only on the undersurface. The varying color patterns and scars on the tail flukes distinguish individual animals. The end of

2002-458: Is specialized for feeding on humpback whales and is the only species in its family found on them. Internal parasites of humpbacks include protozoans of the genus Entamoeba , tapeworms of the family Diphyllobothriidae and roundworms of the infraorder Ascaridomorpha . Humpback whales are found in marine waters worldwide , except for some areas at the equator and High Arctic and some enclosed seas. The furthest north they have been recorded

2093-405: Is that when humpbacks suffered near-extinction during the whaling era, orcas turned to other prey but are now resuming their former practice. There is also evidence that humpback whales will defend against or mob killer whales who are attacking either humpback calves or juveniles as well as members of other species, including seals . The humpback's protection of other species may be unintentional,

Many of Taveuni's best known attractions lie underwater. There are three major, distinct diving areas around

2275-484: The Arabian Sea has been isolated for 70,000 years. The adult humpback whale is generally 14–15 m (46–49 ft), though longer lengths of 16–17 m (52–56 ft) have been recorded. Females are usually 1–1.5 m (3 ft 3 in – 4 ft 11 in) longer than males. The species can reach body masses of 40 metric tons (44 short tons). Calves are born at around 4.3 m (14 ft) long with

2366-601: The IUCN Red List lists the humpback whale as least-concern , with a worldwide population of around 135,000 whales, of which around 84,000 are mature individuals, and an increasing population trend. Regional estimates are around 13,000 in the North Atlantic, 21,000 in the North Pacific, and 80,000 in the southern hemisphere. For the isolated population in the Arabian Sea, only around 80 individuals remain, and this population

2457-527: The International Whaling Commission (IWC) was founded to oversee the industry. They imposed hunting regulations and created hunting seasons. To prevent extinction , IWC banned commercial humpback whaling in 1966. By then, the global population had been reduced to around 5,000. The Soviet Union deliberately under-recorded its catches; the Soviets reported catching 2,820 between 1947 and 1972, but

2912-441: The 19th century, two humpback whales were found dead near repeated oceanic sub-bottom blasting sites, with traumatic injuries and fractures in the ears. Saxitoxin , a paralytic shellfish poisoning from contaminated mackerel, has been implicated in humpback whale deaths. While oil ingestion is a risk for whales, a 2019 study found that oil did not foul baleen and instead was easily rinsed by flowing water. Whale researchers along

3003-618: The Atlantic Coast report that there have been more stranded whales with signs of vessel strikes and fishing gear entanglement in recent years than ever before. The NOAA recorded 88 stranded humpback whales between January 2016 and February 2019. This is more than double the number of whales stranded between 2013 and 2016. Because of the increase in stranded whales, NOAA declared an unusual mortality event in April 2017. Virginia Beach Aquarium 's stranding response coordinator, Alexander Costidis, stated

3094-566: The Biosecurity Authority of Fiji saw a bounty placed on both adult and juvenile American iguanas as well as their eggs. Taveuni is also home to the Taveuni beetle , maroon shining parrot , Fiji goshawk , azure-crested flycatcher , Fiji white-eye , Fiji parrot finch , orange dove , and the kula parrot, and the Australian magpie , introduced to control coconut pests, has proliferated on

3185-630: The Cape Verde population gathers around Iceland and Norway. There is some overlap in the summer ranges of these populations, and West Indies humpbacks have been documented feeding further east. Whale visits into the Gulf of Mexico have been infrequent but have occurred in the gulf historically. They were considered to be uncommon in the Mediterranean Sea , but increased sightings, including re-sightings, indicate that more whales may colonize or recolonize it in

Bouma Forest Park, later renamed Bouma National Heritage Park was established in 1990 after landowning clans became concerned by the threat of logging. The reserve has expanded to cover roughly one third of

3549-519: The conclusion that the two causes of these unusual mortality events were vessel interactions and entanglements. In December 1883, a male humpback swam up the Firth of Tay in Scotland, past what was then the whaling port of Dundee . Harpooned during a failed hunt, it was found dead off Stonehaven a week later. Its carcass was exhibited to the public by a local entrepreneur, John Woods, both locally and then as

In fact, historically, Taveuni was owned and controlled by two distinct Chieftainship, Tikina o Vuna from the south, and one in the north of Taveuni. The Tui Cakau has his land across water from Taveuni island and

3913-662: The future. The North Pacific has at least four breeding populations: off Mexico (including Baja California and the Revillagigedos Islands ), Central America, the Hawaiian Islands , and both Okinawa and the Philippines . The Mexican population forages from the Aleutian Islands to California. During the summer, Central American humpbacks are found only off Oregon and California. In contrast, Hawaiian humpbacks have

4004-446: The genital slit of the female is marked by a round feature, known as the hemispherical lobe, which visually distinguishes males and females. Unique among large whales, humpbacks have bumps or tubercles on the head and front edge of the flippers; the tail fluke has a jagged trailing edge . The tubercles on the head are 5–10 cm (2.0–3.9 in) thick at the base and poke up to 6.5 cm (2.6 in). They are mostly hollow in

4095-489: The genus Megaptera , classifying the humpback as Megaptera longipinna , but in 1932, Remington Kellogg reverted the species names to use Borowski's novaeangliae . The common name is derived from the curving of their backs when diving. The generic name Megaptera from the Ancient Greek mega- μεγα ("giant") and ptera / πτερα ("wing") refer to their large front flippers. The specific name means "New Englander" and

4186-582: The grooves. Water is pushed out through the baleen. In the southern hemisphere, humpbacks have been recorded foraging in large compact gatherings numbering up to 200 individuals. Humpbacks typically hunt their prey with bubble-nets , which is considered to be a form of tool use . A group swims in a shrinking circle while blowing air from their blowholes , capturing prey above in a cylinder of bubbles . They may dive up to 20 m (70 ft) performing this technique. Bubble-netting comes in two main forms; upward spirals and double loops. Upward spirals involve

4277-485: The group over 27 years in response to a change in primary prey. The tubercles on the flippers stall the angle of attack , which both maximizes lift and minimizes drag (see tubercle effect ). This, along with the shape of the flippers, allows the whales to make the abrupt turns necessary during bubble-feeding. At Stellwagen Bank off the coast of the US state of Massachusetts , humpback whales have been recorded foraging at

4368-595: The growth of commercial whale watching was built on the humpback whale. The species' highly active surface behaviors and tendency to become accustomed to boats have made them easy to observe, particularly for photographers. In 1975, humpback whale tours were established in New England and Hawaii. This business brings in a revenue of $ 20 million per year for Hawaii's economy. While Hawaiian tours have tended to be commercial, New England and California whale watching tours have introduced educational components. As of 2018,

4459-574: The island are high because the central mountains produce precipitation by orographic uplift . As much as 10 metres (33 feet) of rain falls annually on the eastern side of the island, but the western side is sheltered from the southeast trade winds by the ridge that runs the length of the island. The central ridge experiences a wet upland climate which supports montane and submontane forests. Near Mount Koroturanga, 9,970 mm of mean, annual rainfall has been recorded. A 2011 study identified coastal erosion , flooding and water availability and supply as

4550-576: The island of Taveuni, namely the Ravilevu Nature Reserve on the east coast, and the Taveuni Forest Reserve in the middle of the island. The potential to be nominated as a World Heritage Site contributes to the island's national significance, as outlined in Fiji's Biodiversity Strategy and Action Plan. The population is concentrated mostly on the more sheltered western side of the island. Taveuni has eight major villages. Halfway down

4641-444: The island, including Uluigalau , Fiji's second highest peak at 1,241 metres (4,072 feet), and Des Vœux Peak , next in height at 1,195 metres (3,921 feet). There have been at least 58 volcanic eruptions since the first human settlement around 950-750 BC, all of which affected the southern two-thirds of the island. Major eruptions from 300 to 500 AD caused abandonment of the southern areas until about 1100 AD. The latest eruption produced

South of Vuna village and the lagoon, jet black rocks litter an area known as the South Cape where Taveuni's last volcanic eruption spilled into the sea around 500 years ago. The highlight of the region is the Matamaiqi blowhole with geysers created by trade winds crashing against the volcanic rocks. About 20 minutes on foot from the town of Waiyevo

4823-508: The island. In January 2003, Severe Tropical Cyclone Ami crossed the island. In January 2008, Cyclone Gene caused widespread damage on the island. In March 2010, the island was hit by Severe Tropical Cyclone Tomas . The eye of the storm passed within 30 km of the island and produced a significant tidal surge and high waves. Nearly all plants and animals indigenous to Fiji are found on Taveuni, which has suffered less devastation from land clearance than other areas of Fiji. The absence of

4914-415: The island. The critically endangered red-throated lorikeet has been found here. In total, 22 regional endemic bird species have been recorded on Taveuni. The total number of bird species found on the island is closer to 100. The island's agricultural output is a significant contributor to the Fijian economy. Copra has been traditionally the most important crop produced on Taveuni, and has always been

5005-415: The island. To the north of Taveuni lie in close proximity the islands of Qamea and Matagi with their surrounding reef systems. The Rainbow Reef and Vuna Reef are famous for diving and snorkeling, respectively. The Rainbow Reef, on the western side of the narrow Somosomo Strait between Taveuni and Vanua Levu, is known as one of the world's premier soft coral dive areas and the soft coral capital of

5096-573: The late 1860s, the Tongan warlord Enele Ma'afu , who had conquered the Lau Islands , was defeated by the Tui Cakau's army in a skirmish at Somosomo. Several islands that sided with Ma'afu were sold by the Tui Cakau at that time to European settlers as punishment, and their inhabitants were moved to Taveuni. The villages of Lovonivonu and Kanacea are populated with their descendants. In fact, Enele Ma'afu

C. reginae digs deep into the skin, while attachments by C. diadema are more superficial. The size of the latter species provides more sites for attachment for other barnacles. Barnacles are considered to be epibionts rather than parasites as they do not feed on the whales, though they can affect their swimming by increasing drag . The whale louse species Cyamus boopis

5278-408: The main natural predators of humpback whales. Like other large whales, the humpback was a target for the whaling industry. Humans once hunted the species to the brink of extinction ; its population fell to around 5,000 by the 1960s. Numbers have partially recovered to some 135,000 animals worldwide, while entanglement in fishing gear , collisions with ships, and noise pollution continue to affect

5369-419: The male that is closest to the female is known as the "principal escort", who fights off the other suitors known as "challengers". Other males, called "secondary escorts", trail further behind and are not directly involved in the conflict. Agonistic behavior between males consists of tail slashing, ramming, and head-butting. Males have also been observed engaging in copulation with each other . Gestation in

5460-418: The most significant impacts of climate change on some of the villages on Taveuni. In 1643, Abel Tasman became the first European to sight Taveuni. Visibility was poor, and he mistook the peaks of Taveuni for separate islands. Historically, Vuna was considered the paramount village on Taveuni when the Tui Cakau (Ratu Yavala) resided there, but tribal warfare eventually established the supremacy of Somosomo. In

5551-605: The movements of the tail fluke. Humpbacks are able to flap and rotate their flippers in a manner similar to California sea lions . Humpbacks rest at the surface with their bodies lying horizontally. They frequent shallow seamounts, commonly exploring depths of up to 80 meters (260 feet) and occasionally venturing into deep dives reaching up to 616 meters (2,020 feet). These deeper descents are believed to serve various purposes, including navigational guidance, communication with fellow humpback whales, and facilitation of feeding activities. Dives typically do not exceed five minutes during

In the North Atlantic, there are two separate wintering populations, one in the West Indies , from Cuba to northern Venezuela, and the other in the Cape Verde Islands and northwest Africa. During summer, West Indies humpbacks congregate off New England , eastern Canada, and western Greenland , while

5733-1339: The northern hemisphere, songs change more gradually while southern hemisphere songs go through cyclical "revolutions". Humpback whales are reported to make other vocalizations. "Snorts" are quick low-frequency sounds commonly heard among animals in groups consisting of a mother–calf pair and one or more male escort groups. These likely function in mediating interactions within these groups. "Grumbles" are also low in frequency but last longer and are more often made by groups with one or more adult males. They appear to signal body size and may serve to establish social status. "Thwops" and "wops" are frequency modulated vocals, and may serve as contact calls both within and between groups. High-pitched "cries" and "violins" and modulated "shrieks" are normally heard in groups with two or more males and are associated with competition. Humpback whales produce short, low-frequency "grunts" and short, modulated "barks" when joining new groups. Visible scars indicate that orcas prey upon juvenile humpbacks. A 2014 study in Western Australia observed that when available in large numbers, young humpbacks can be attacked and sometimes killed by orcas. Moreover, mothers and (possibly related) adults escort calves to deter such predation. The suggestion

5915-403: The region. In Hawaii, humpback whales have been recorded vocalizing for as long as seven hours. Songs are divided into layers; "subunits", "units", "subphrases", "phrases" and "themes". A subunit refers to the discontinuities or inflections of a sound while full units are individual sounds, similar to musical notes . A succession of units creates a subphrase, and a collection of subphrases make up

6006-448: The seafloor for sand lances. This involves the whales flushing out the fish by brushing their jaws against the bottom. Mating and breeding take place during the winter months, which is when females reach estrus and males reach peak testosterone and sperm levels. Humpback whales are promiscuous , with both sexes having multiple partners. Males will frequently trail both lone females and cow–calf pairs. These are known as "escorts", and

6097-516: The southeastern Pacific (stock G), southwestern Atlantic (stock A), southeastern Atlantic (stock B), southwestern Indian Ocean (stock C), southeastern Indian Ocean (stock D), southwestern Pacific (stock E), and the Oceania stock (stocks E–F). Stock G breeds in tropical and subtropical waters off the west coast of Central and South America and forages along the west coast of the Antarctic Peninsula ,

6188-437: The southern hemisphere around 880,000 years ago and colonized the northern hemisphere 200,000–50,000 years ago. A 2014 genetic study suggested that the separate populations in the North Atlantic, North Pacific, and Southern Oceans have had limited gene flow and are distinct enough to be subspecies , with the scientific names of M. n. novaeangliae , M. n. kuzira and M. n. australis respectively. A non-migratory population in

6279-469: The southern hemisphere is the Antarctic krill . Further north, the northern krill and various species of Euphausia and Thysanoessa are consumed. Fish prey include herring , capelin , sand lances and Atlantic mackerel . Like other rorquals, humpbacks are "gulp feeders", swallowing prey in bulk, while right whales and bowhead whales are skimmers. The whale increases its mouth gape by expanding

6370-617: The species lasts 11.5 months, and females reproduce every 2 years. Fetuses start out with teeth and develop their baleen during the very last months of their gestation. Humpback whale births have been rarely observed. One birth witnessed off Madagascar occurred within four minutes. Mothers typically give birth in mid-winter, usually to a single calf. Young start out with furled dorsal fins which straighten and stiffen as they get older. Calves with furled fin spend more time traveling and surfacing to breathe while calves with straighter fins can hold their breaths longer and can rest and circle around at

6461-496: The species. The humpback was first identified as baleine de la Nouvelle Angleterre by Mathurin Jacques Brisson in his Regnum Animale of 1756. In 1781, Georg Heinrich Borowski described the species, converting Brisson's name to its Latin equivalent, Balaena novaeangliae . In 1804, Bernard Germain de Lacépède shifted the humpback from the family Balaenidae , renaming it B. jubartes . In 1846, John Edward Gray created

6552-577: The staple of the local economy. In recent times farmers have mainly shifted to growing taro , kava and other speciality crops like vanilla , along with tropical fruit and coffee . During the American Civil War (1861–1865), cotton was raised on Taveuni and exported to Europe. Sugarcane was also grown for a brief period. Livestock such as sheep , cattle and poultry are also raised, but animal husbandry lags behind crop production in terms of economic importance. In recent times, tourism has become

6643-589: The summer but are normally 15–20 minutes during the winter. As it dives, a humpback typically raises its tail fluke, exposing the underside. Humpbacks have been observed to produce oral "bubble clouds" when near another individual, possibly in the context of "aggression, mate attraction, or play". Humpbacks may also use bubble cloud as "smoke screens" to escape from predators. Humpback whales feed from spring to fall. They are generalist feeders, their main food items being krill , copepods , other plankton and small schooling fish. The most common krill species eaten in

6734-568: The surface more. Older calves are also away from their mothers more. Calves suckle for up to a year but can eat adult food in six months. Humpbacks are sexually mature at 5–10 years, depending on the population. Humpback whales possibly live over 50 years. Male humpback whales produce complex songs during the winter breeding season. These vocals range in frequency between 100 Hz and 4 kHz, with harmonics reaching up to 24 kHz or more, and can travel at least 10 km (6.2 mi). Males may sing for between 4 and 33 minutes, depending on

6825-504: The surface, performing aerial behaviors such as breaching and surface slapping with the tail ( lobtailing ) and flippers. These may be forms of play and communication and/or for removing parasites. The species is a slower swimmer than other rorquals, cruising at 7.9–15.1 km/h (4.9–9.4 mph). When threatened, a humpback may speed up to 27 km/h (17 mph). Their proportionally long pectoral fins give them great propulsion and allow them to swim in any direction independently of

6916-413: The tips of the temporal lobes , and weighed around 4.6 kg (10 lb). Its brain has similar complexity to the brains of smaller whales and dolphins. Computer models of the middle ear suggest that the humpback can hear at frequencies between 15 Hz and 3 kHz "when stimulated at the tympanic membrane ", and between 200 Hz and 9 kHz "if stimulated at the thinner region of the tympanic bone adjacent to

7007-562: The true number was over 48,000. As of 2004, hunting was restricted to a few animals each year off the Caribbean island of Bequia in Saint Vincent and the Grenadines . The take is not believed to threaten the local population. Japan had planned to kill 50 humpbacks in the 2007/08 season under its JARPA II research program. The announcement sparked global protests. After a visit to Tokyo by

7098-504: The tympanic membrane". This is consistent with their vocalization ranges. As in all cetaceans, the respiratory tract of the humpback whale is connected to the blow and not the mouth, though appears to be able to unlock the epiglottis and larynx and move them towards the oral cavity, allowing them to blow bubbles from there. The vocal folds of the humpback are more horizontally positioned than those of land mammals which allows them to produce underwater calls. These calls are amplified by

7189-534: The west coast is the administrative centre of Waiyevo . The largest urban area, however, comprises the twin villages of Somosomo and Naqara . As the traditional fiefdom of the Tui Cakau , one of Fiji's highest-ranked chiefs, Somosomo is regarded as the capital of the Tovata Confederacy , while Naqara, an Indo-Fijian settlement, is the island's commercial centre. The main hospital is located at Waiyevo while

7280-554: The west coast of Africa and is further divided into Bl and B2 subpopulations, the former ranging from the Gulf of Guinea to Angola and the latter ranging from Angola to western South Africa. Stock B whales have been recorded foraging in waters to the southwest of the continent, mainly around Bouvet Island . Comparison of songs between those at Cape Lopez and Abrolhos Archipelago indicate that trans-Atlantic mixings between stock A and stock B whales occur. Stock C whales winter around southeastern Africa and surrounding waters. This stock

7371-603: The western coast of Australia, and forage in the southern region of the Kerguelen Plateau . Stock E is divided into E1, E2, and E3 stocks. E1 whales have a breeding range off eastern Australia and Tasmania ; their main feeding range is close to Antarctica, mainly within 130°E and 170°W . The Oceania stock is divided into the New Caledonia (E2), Tonga (E3), Cook Islands (F1) and French Polynesia (F2) subpopulations. This stock's feeding grounds mainly range from around

7462-452: The whale's tail to cripple and bleed the whale before she managed to drown the whale by biting onto its head and pulling it underwater. Humpback whales often have barnacles living on their skin; the most common being the acorn barnacle species Coronula diadema and Coronula reginae , which in turn are sites for attachment for goose barnacle species like Conchoderma auritum and Conchoderma virgatum . They are most abundant at

7553-737: The whales blowing air from their blowhole continuously as they circle towards the surface, creating a spiral of bubbles. Double loops consist of a deep, long loop of bubbles that herds the prey, followed by slapping the surface and then a smaller loop that prepares the final capture. Combinations of spiraling and looping have been recorded. After the humpbacks create the "nets", the whales swim into them with their mouths gaping and ready to swallow. Bubble-net feeding has also been observed in solitary humpbacks, which can consume more food per mouthful without tiring, particularly with low-density prey patches. Using network-based diffusion analysis , one study argued that whales learned lobtailing from other whales in

7644-468: The world The horseshoe-shaped Vuna Lagoon, near the southern end of the island, is much appreciated by divers for the opportunity to see larger pelagic and schooling fish species on the exposed southern side of the reef, whereas the sheltered western parts provide pristine soft and hard coral gardens. Migrating humpback whales pass the island in July. An interesting note is that the island of Taveuni crosses

7735-597: Was Ratu Sir Penaia Ganilau (1918–1993), Fiji's last Governor-General and first President , who was also Tui Cakau . The Ganilau family is a branch of the Ai Sokula clan, to which the present Tui Cakau and former Cabinet Minister Ratu Naiqama Lalabalavu also belongs. He died in 1993, and was buried there. Another notable Taveunian is Fiji's former First Lady , Adi Salaseini Kavunono , wife of President Ratu Josefa Iloilo (2000–2009). Ratu Jone Yavala Kubuabola served as Fiji's Minister for Finance from 2000 to 2006. He

7826-712: Was also a former Governor of the Reserve Bank of Fiji . Ratu Inoke Kubuabola (younger brother of Ratu Jone Yavala Kubuabola) is a Fijian politician who served as Leader of the Opposition in 1999 and 2000. He became leader of the Soqosoqo ni Vakavulewa ni Taukei , or SVT, following its defeat in the 1999 election and the subsequent resignation of its leader, the defeated Prime Minister Sitiveni Rabuka , from Parliament. Kubuabola served as Fiji's High Commissioner to Papua New Guinea from 2002 to 2005. In late 2005, he attempted to handle

7917-543: Was involved in an internal Cakaudrove campaign. It was an opportune time for Wainiqolo to initiate his campaign whilst Golea was involved in an internal struggle on Vanualevu. Ma’afu never forgave Wainiqolo for the act that he did and removed all land allocated to him. Historians saw this anger as confirmation that Ma’afu was not part of the Wainiqolo plot to conquer Tui Cakau while he was away in Tonga. The unprovoked attack by Wainiqolo

8008-590: Was named Minister for Foreign Affairs by the Interim Government, a position he still holds as of 2015 . The Kubuabola family is a branch of the Ai Sokula clan. Isikeli Vuruna , a rugby union footballer, was born on Taveuni. Both Avengers of the Reef and Return to the Blue Lagoon were partially filmed on the island. Fantasy Island (film) was also filmed on the island. Humpback whale This

8099-540: Was not defeated by the Tui Cakau's army as stated above. He was in Tonga at that time. In July 1862, Ma’afu went for a visit to Tonga with Tui Bua to seek resolution about his campaign in Fiji with the Tongan Parliament. During his absence, Wainiqolo, one of his lieutenants, waged war on Golea. Wainiqolo was shot dead on the beach at Wairiki and the Tongans were slaughtered. Wainiqolo had taken Tui Cakau prisoner when Golea

8190-497: Was probably given by Brisson due to regular sightings of humpbacks off the coast of New England . Humpback whales are rorquals , members of the family Balaenopteridae , which includes the blue , fin , Bryde's , sei and minke whales . A 2018 genomic analysis estimates that rorquals diverged from other baleen whales in the late Miocene , between 10.5 and 7.5 million years ago. The humpback and fin whale were found to be sister taxon (see phylogenetic tree below). There

8281-498: Was regarded by the Tui Cakau as cancelling his obligation to respect the right of Ma’afu to islands which had been formerly part of Cakaudrove chiefdom. Golea proceeded to resell the whole of Vanuabalavu to Europeans. On 3 February 1865, a Court of Arbitration was convened by British Consul Jones who handed down the Court's decision that Ma’afu was the lawful owner of Vanuabalavu and associated islands. Ma’afu immediately executed an affidavit
