86-589: In 1863, the elder Hagenbeck began collecting exotic animals that came through Hamburg's port . By the 1870s, the trade had proved more lucrative than his fish shop, and Hagenbeck had become one of the most prominent exotic animal traders in all of Europe. In 1874, the younger Hagenbeck traveled around the world collecting animals. Among his collections, however, were also human beings whom he exhibited in " human zoos ". Hagenbeck decided to exhibit Samoan and Sámi people as "purely natural" populations. The Sámi were presented with their tents , weapons, and sleds , beside

172-537: A central trading node for sea-borne trade. With discovery of the Americas and the emerging transatlantic trade, Hamburg exceeded all other German ports. During the second half of the 19th century, Hamburg became Central Europe's main hub for transatlantic passenger and freight travel, and from 1871 onward it was Germany's principal port of trade. In her time the Hamburg America Line was the largest shipping company in

258-527: A change of government in 2001. The port is administered by the Hamburg Port Authority. The Hamburg Port Authority is described as having adopted an innovative approach. In November 2016 the Hamburg Port Authority ordered a modern fireboat budgeted at 16 million euros . Hamburg is a major cruise destination and one of Europe's largest ports of call for cruise passengers traveling the Atlantic, or

344-612: A deep depression. Then during the Bombing of Hamburg in World War II the original zoo was destroyed. After the war the zoo was rebuilt. The private zoo is still run by the Hagenbeck family. In July 1956, forty five rhesus monkeys escaped from the zoo and ran wild in Hamburg . The incident resulted in calls for help from shocked housewives who met monkeys in their bedrooms and bathtubs. Some of

430-442: A diverse and opportunistic diet, feeding on more than 60 genera of marine organisms, including shrimp , crabs, priapulids , spoon worms , tube worms , soft corals , tunicates , sea cucumbers , various mollusks (such as snails , octopuses , and squid ), some types of slow-moving fish , and even parts of other pinnipeds. However, it prefers benthic bivalve mollusks , especially clams , for which it forages by grazing along

516-616: A group of reindeer . In 1874, Hagenbeck opened a zoo facility in Hamburg, called Carl Hagenbeck's Tierpark, while he continued exhibiting humans. In 1876, he began exhibiting Nubians all across Europe. He also dispatched an agent to Labrador to secure a number of "Esquimaux" ( Inuit ) from the settlement of Hebron ; these Inuit (see Abraham Ulrikab ) were exhibited in the Hamburg Tierpark. Though initially popular, Hagenbeck's shows gradually began to decline in popularity, especially once

602-687: A new facility outside of Hamburg which he called Tierpark Hagenbeck (without the 'H' that was in Thierpark) which is still the location of the facility today. Hagenbeck sought to design the entire zoo with his panorama system. He also sought to demonstrate that animals from warmer climates did not need to live in expensive, humid, foreboding buildings. Instead, Hagenbeck again sought to make his displays realistic. Using data that he had compiled running his circus, Hagenbeck had estimates of how high and far different animals could leap. Using this data, he built moats filled with water or an empty pit that he determined

688-573: A peak in the 1970s-1980s, but subsequently, walrus numbers have again declined. Early aerial censuses of Pacific walrus conducted at five-year intervals between 1975 and 1985 estimated populations of above 220,000 in each of the three surveys. In 2006, the population of the Pacific walrus was estimated to be around 129,000 on the basis of an aerial census combined with satellite tracking. There were roughly 200,000 Pacific walruses in 1990. The much smaller population of Atlantic walruses ranges from

774-476: A port complex with warehousing and transshipment facilities. The extensive free port was established when Hamburg joined the German Customs Union . It enabled duty-free storing of imported goods and also importing of materials which were processed, re-packaged, used in manufacturing and then re-exported without incurring customs duties. The free port was abandoned in 2013. The port is almost as old as

860-556: A significant portion (about 42%) of struck and lost animals. Several hundred are removed annually around Greenland. The sustainability of these levels of harvest is difficult to determine given uncertain population estimates and parameters such as fecundity and mortality . The Boone and Crockett Big Game Record book has entries for Atlantic and Pacific walrus. The recorded largest tusks are just over 30 inches and 37 inches long respectively. The effects of global climate change are another element of concern. The extent and thickness of

946-518: A similar arrangement, though related to the Czech Republic exclusively. The Speicherstadt , one of Hamburg's architectural icons today, is a large wharf area of 350,000 m floor area on the northern shore of the river, built in the 1880s as part of the free port and to cope with the growing quantity of goods stored in the port. Hamburg shipyards lost fleets twice after World War I and World War II. Moreover, during World War II, Hamburg harbour

1032-445: A single ancestor, or diphyletic , recent genetic evidence suggests all three descended from a caniform ancestor most closely related to modern bears. Recent multigene analysis indicates the odobenids and otariids diverged from the phocids about 20–26 million years ago, while the odobenids and the otariids separated 15–20 million years ago. Odobenidae was once a highly diverse and widespread family, including at least twenty species in

1118-515: A single walrus was sighted on the shores of the Baltic Sea - at Rügen Island, Germany , Mielno , Poland and Skälder Bay , Sweden . In July 2022, there was a report of a lost, starving walrus (nicknamed as Stena ) in the coastal waters of the towns of Hamina and Kotka in Kymenlaakso , Finland , that, despite rescue attempts, died of starvation when the rescuers tried to transport it to

1204-454: A substantial breeding population occurred on isolated Sable Island , 100 mi (160 km) southeast of Nova Scotia and 500 mi (800 km) due east of Portland, Maine , until the early Colonial period. Abundant walrus remains have also been recovered from the southern North Sea dating to the Eemian interglacial period, when that region would have been submerged as it is today, unlike

1290-692: A vital art form. According to Adolf Erik Nordenskiöld , European hunters and Arctic explorers found walrus meat not particularly tasty, and only ate it in case of necessity; however walrus tongue was a delicacy. Walrus hunts are regulated by resource managers in Russia , the United States, Canada, and Greenland , and by representatives of the respective hunting communities. An estimated four to seven thousand Pacific walruses are harvested in Alaska and in Russia, including

1376-436: A year before weaning, but the young can spend up to five years with the mothers. Walrus milk contains higher amounts of fats and protein compared to land animals but lower compared to phocid seals . This lower fat content in turn causes a slower growth rate among calves and a longer nursing investment for their mothers. Because ovulation is suppressed until the calf is weaned, females give birth at most every two years, leaving

1462-686: Is Scandinavian. The Norwegian manuscript Konungs skuggsjá , thought to date from around AD 1240, refers to the walrus as rosmhvalr in Iceland and rostungr in Greenland (walruses were by now extinct in Iceland and Norway, while the word evolved in Greenland). Several place names in Iceland, Greenland and Norway may originate from walrus sites: Hvalfjord, Hvallatrar and Hvalsnes to name some, all being typical walrus breeding grounds. The archaic English word for walrus— morse —is widely thought to have come from

1548-828: Is a seaport on the river Elbe in Hamburg , Germany , 110 kilometres (68 mi) from its mouth on the North Sea . Known as Germany's "Gateway to the World" ( Tor zur Welt ), it is the country's largest seaport by volume. In terms of TEU throughput , Hamburg is the third-busiest port in Europe (after Rotterdam and Antwerp ) and 15th-largest worldwide. In 2014, 9.73 million TEUs (20-foot standard container equivalents) were handled in Hamburg. The port covers an area of 73.99 square kilometres (28.57 sq mi) (64.80 km usable), of which 43.31 km (34.12 km ) are land areas. The branching Elbe creates an ideal place for

1634-657: Is a large pinniped marine mammal with discontinuous distribution about the North Pole in the Arctic Ocean and subarctic seas of the Northern Hemisphere . It is the only extant species in the family Odobenidae and genus Odobenus . This species is subdivided into two subspecies : the Atlantic walrus ( O. r. rosmarus ), which lives in the Atlantic Ocean , and the Pacific walrus ( O. r. divergens ), which lives in

1720-471: Is also one of the city's major attractions, both as a vital, industrial, and logistical centre, and as a backdrop for modern culture and harbour history. These include several museum ships, musical theatres, bars, restaurants, and hotels – and even a floating church. The annual celebration of the port's birthday ( Hafengeburtstag ), during the first weekend of May, is one of Hamburg's biggest public events. National and international visitors come to experience

1806-499: Is estimated to have been at least 2,300 kg (5,000 lb). The Atlantic subspecies weighs about 10–20% less than the Pacific subspecies. Male Atlantic walrus weigh an average of 900 kg (2,000 lb). The Atlantic walrus also tends to have relatively shorter tusks and somewhat more of a flattened snout . Females weigh about two-thirds as much as males, with the Atlantic females averaging 560 kg (1,230 lb), sometimes weighing as little as 400 kg (880 lb), and

1892-411: Is highly variable, they generally have relatively few teeth other than the tusks. The maximal number of teeth is 38 with dentition formula: 3.1.4.2 3.1.3.2 , but over half of the teeth are rudimentary and occur with less than 50% frequency, such that a typical dentition includes only 18 teeth 1.1.3.0 0.1.3.0 Surrounding the tusks is a broad mat of stiff bristles ("mystacial vibrissae "), giving

1978-414: Is little evidence to prove this. Due to its great size and tusks, the walrus has only two natural predators: the orca and the polar bear . The walrus does not, however, comprise a significant component of either of these predators' diets. Both the orca and the polar bear are also most likely to prey on walrus calves. The polar bear often hunts the walrus by rushing at beached aggregations and consuming

2064-408: Is more like that of true seals, relying less on flippers and more on sinuous whole body movements. Also like phocids, it lacks external ears. The extraocular muscles of the walrus are well-developed. This and its lack of orbital roof allow it to protrude its eyes and see in both a frontal and dorsal direction. However, vision in this species appears to be more suited for short-range. While this

2150-625: Is restricted according to a CITES Appendix 3 listing. In October 2017, the Center for Biological Diversity announced they would sue the U.S. Fish and Wildlife Service to force it to classify the Pacific Walrus as a threatened or endangered species. In 1952, walruses in Svalbard were nearly gone due to ivory hunting over a 300 years period, but the Norwegian government banned their commercial hunting and

2236-663: The Chukchi Sea through the relatively narrow Bering Strait . The majority of the population of the Pacific walrus spends its summers north of the Bering Strait in the Chukchi Sea of the Arctic Ocean along the northern coast of eastern Siberia , around Wrangel Island , in the Beaufort Sea along the northern shore of Alaska south to Unimak Island , and in the waters between those locations. Smaller numbers of males summer in

2322-787: The Gulf of Anadyr on the southern coast of the Siberian Chukchi Peninsula , and in Bristol Bay off the southern coast of Alaska, west of the Alaska Peninsula . In the spring and fall, walruses congregate throughout the Bering Strait, reaching from the western coast of Alaska to the Gulf of Anadyr. They winter over in the Bering Sea along the eastern coast of Siberia south to the northern part of

2408-484: The Kamchatka Peninsula , and along the southern coast of Alaska. A 28,000-year-old fossil walrus was dredged up from the bottom of San Francisco Bay , indicating that Pacific walruses ranged that far south during the last Ice Age . Commercial harvesting reduced the population of the Pacific walrus to between 50,000 and 100,000 in the 1950s–1960s. Limits on commercial hunting allowed the population to increase to

2494-708: The Korkeasaari Zoo for treatment. Walruses prefer shallow shelf regions and forage primarily on the sea floor, often from sea ice platforms. They are not particularly deep divers compared to other pinnipeds; the deepest dives in a study of Atlantic walrus near Svalbard were only 31 ± 17 m (102 ± 56 ft). However, a more recent study recorded dives exceeding 500 metres (1,600 ft) in Smith Sound , between NW Greenland and Arctic Canada – in general, peak dive depth can be expected to depend on prey distribution and seabed depth. The walrus has

2580-455: The Pacific Ocean . Adult walrus are characterised by prominent tusks and whiskers , and considerable bulk: adult males in the Pacific can weigh more than 2,000 kilograms (4,400 pounds) and, among pinnipeds , are exceeded in size only by the two species of elephant seals . Walrus live mostly in shallow waters above the continental shelves , spending significant amounts of their lives on

2752-463: The blastula in suspended development before it implants itself in the uterus. This strategy of delayed implantation , common among pinnipeds, presumably evolved to optimize both the mating season and the birthing season, determined by ecological conditions that promote newborn survival. Calves are born during the spring migration, from April to June. They weigh 45 to 75 kg (99 to 165 lb) at birth and are able to swim. The mothers nurse for over

2838-554: The history of Hamburg itself. Founded on 7 May 1189 by Frederick I at a strategic location near the mouth of the Elbe, it has been Central Europe 's main port for centuries and enabled Hamburg to develop early into a leading city of trade with a rich and proud bourgeoisie. During the age of the Hanseatic League from the 13th to 16th century, Hamburg was considered second only to the port and city of Lübeck in terms of its position as

2924-413: The photograph became more and more common, and Hagenbeck's exhibits began to look less and less real in comparison. After one exhibit, Hagenbeck was left with a large number of elephants and no one to purchase them. Unable to sell, he started a circus. To counter the declining popularity of his human zoos , Hagenbeck began working on making his displays more realistic, techniques that would later influence

3010-566: The sea ice looking for benthic bivalve molluscs . Walruses are relatively long-lived, social animals, and are considered to be a " keystone species " in the Arctic marine regions. The walrus has played a prominent role in the cultures of many indigenous Arctic peoples , who have hunted it for meat, fat, skin, tusks, and bone. During the 19th century and the early 20th century, walrus were widely hunted for their blubber , walrus ivory , and meat. The population of walruses dropped rapidly all around

3096-458: The 18th and 19th centuries, the walrus was heavily exploited by American and European sealers and whalers , leading to the near- extirpation of the Atlantic subspecies. As early as 1871 traditional hunters were expressing concern about the numbers of walrus being hunted by whaling fleets. Commercial walrus harvesting is now outlawed throughout its range, although Chukchi , Yupik and Inuit peoples are permitted to kill small numbers towards

3182-422: The Arctic region. It has rebounded somewhat since, though the populations of Atlantic and Laptev walruses remain fragmented and at low levels compared with the time before human interference. The origin of the word walrus derives from a Germanic language , and it has been attributed largely to either Dutch or Old Norse . Its first part is thought to derive from a word such as Old Norse hvalr ('whale') and

3268-496: The Atlantic and Pacific subspecies indicate very restricted gene flow, but relatively recent separation, estimated at 500,000 and 785,000 years ago. These dates coincide with the hypothesis derived from fossils that the walrus evolved from a tropical or subtropical ancestor that became isolated in the Atlantic Ocean and gradually adapted to colder conditions in the Arctic. The modern walrus is mostly known from Arctic regions, but

3354-480: The Canadian Arctic, across Greenland , Svalbard , and the western part of Arctic Russia. There are eight hypothetical subpopulations of Atlantic walruses, based largely on their geographical distribution and movements: five west of Greenland and three east of Greenland. The Atlantic walrus once ranged south to Sable Island , off of Nova Scotia ; as late as the 18th century, they could be found in large numbers in

3440-716: The Greater Gulf of St. Lawrence region, sometimes in colonies of 7-8,000 individuals. This population was nearly eradicated by commercial harvest; their current numbers, though difficult to estimate, probably remain below 20,000. In April 2006, the Canadian Species at Risk Act listed the populations of northwestern Atlantic walrus in Québec , New Brunswick, Nova Scotia , Newfoundland and Labrador as having been eradicated in Canada. A genetically distinct population existed in Iceland that

3612-430: The Pacific female averaging 800 kg (1,800 lb). Length typically ranges from 2.2 to 3.6 m (7 ft 3 in to 11 ft 10 in). Newborn walruses are already quite large, averaging 33 to 85 kg (73 to 187 lb) in weight and 1 to 1.4 m (3 ft 3 in to 4 ft 7 in) in length across both sexes and subspecies. All told, the walrus is the third largest pinniped species, after

3698-519: The Pacific subspecies far exceeds normal dimensions. In 1909, a walrus hide weighing 500 kg (1,100 lb) was collected from an enormous bull in Franz Josef Land , while in August 1910, Jack Woodson shot a 4.9-metre-long (16 ft) walrus, harvesting its 450 kg (1,000 lb) hide. Since a walrus's hide usually accounts for about 20% of its body weight, the total body mass of these two giants

3784-490: The Pacific, but the importance of seals in the walrus diet is under debate. There have been isolated observations of walruses preying on seals up to the size of a 200 kg (440 lb) bearded seal . Rarely, incidents of walruses preying on seabirds, particularly the Brünnich's guillemot ( Uria lomvia ), have been documented. Walruses may occasionally prey on ice-entrapped narwhals and scavenge on whale carcasses but there

3870-461: The animal zoo. In the 1890s Hagenbeck created his first "panorama" exhibit and patented the idea in 1896. The display was the "Northern Panorama", the foreground featured seals and walruses in a pool. Hidden from the zoo's patrons was a moat behind the pool. Beyond the moat were reindeer , and beyond a second hidden moat were polar bears . By hiding the moats, the animals appeared to be together in one landscape. In 1907, Hagenbeck constructed

3956-486: The animals could not cross. Using moats to separate animals that did not swim, one could look across an expanse of the zoo and see many animals at once, as if in the wild. Previously, zoos had not grouped animals by species, but Hagenbeck revolutionized the layout of zoos, grouping his animals by species. Hagenbeck's design was a popular success. In 1911, Hagenbeck designed the Rome Zoo in the same style. In 1913, he designed

4042-662: The biological walrus's appetite for bivalve mollusks, oysters, primarily nearshore and intertidal inhabitants, these organisms in fact comprise an insignificant portion of its diet in captivity. The "walrus" in the cryptic song " I Am the Walrus " by the Beatles is a reference to the Lewis Carroll poem. Another appearance of the walrus in literature is in the story "The White Seal" in Rudyard Kipling 's The Jungle Book , where it

4128-623: The end of each summer. Traditional hunters used all parts of the walrus. The meat, often preserved, is an important winter nutrition source; the flippers are fermented and stored as a delicacy until spring; tusks and bone were historically used for tools, as well as material for handicrafts; the oil was rendered for warmth and light; the tough hide made rope and house and boat coverings; and the intestines and gut linings made waterproof parkas. While some of these uses have faded with access to alternative technologies, walrus meat remains an important part of local diets, and tusk carving and engraving remain

4214-461: The festivities. Tugboats perform "ballets", old galleons and new cruise ships are open for tours, and fireworks explode at night. Tour guides on boat tours in the port are called " he lüchts " (Low German for "he is lying"), after an often used call of dock workers when they overheard the stories told to tourists. Walrus O. rosmarus rosmarus O. rosmarus divergens O. rosmarus laptevi (debated) The walrus ( Odobenus rosmarus )

4300-414: The first monkey-rock exhibit, in this case an artificial crag with a 16-foot (4.9 m) moat. The rock was populated by around 200 hamadryas baboons . Hagenbeck called his design an animal paradise where "animals would live beside each other in harmony and where the fight for survival would be eliminated." Hagenbeck died in 1913, but his zoo remained popular until the political situation in Europe swept

4386-401: The increase of stampeding deaths crowding the shorelines of the Chukchi Sea between eastern Russia and western Alaska. Analysis of trends in ice cover published in 2012 indicate that Pacific walrus populations are likely to continue to decline for the foreseeable future, and shift further north, but that careful conservation management might be able to limit these effects. Currently, two of

4472-437: The individuals crushed or wounded in the sudden exodus, typically younger or infirm animals. The bears also isolate walruses when they overwinter and are unable to escape a charging bear due to inaccessible diving holes in the ice. However, even an injured walrus is a formidable opponent for a polar bear, and direct attacks are rare. Armed with its ivory tusks, walruses have been known to fatally injure polar bears in battles if

4558-794: The intervening glacial lowstand when the shallow North Sea was dry land. Fossils known from San Francisco , Vancouver , and the Atlantic US coast as far south as North Carolina have been referred to glacial periods. An isolated population in the Laptev Sea was considered by some authorities, including many Russian biologists and the canonical Mammal Species of the World , to be a third subspecies, O. r. laptevi (Chapskii, 1940), but has since been determined to be of Pacific walrus origin. While some outsized Pacific males can weigh as much as 2,000 kg (4,400 lb), most weigh between 800 and 1,700 kg (1,800 and 3,700 lb). An occasional male of

4644-404: The large numbers of organisms actually consumed by the walrus, its foraging has a large peripheral impact on benthic communities. It disturbs ( bioturbates ) the sea floor, releasing nutrients into the water column, encouraging mixing and movement of many organisms and increasing the patchiness of the benthos . Seal tissue has been observed in a fairly significant proportion of walrus stomachs in

4730-502: The largest of any land mammal, both in absolute size and relative to body size. Walruses live to about 20–30 years old in the wild. The males reach sexual maturity as early as seven years, but do not typically mate until fully developed at around 15 years of age. They rut from January through April, decreasing their food intake dramatically. The females begin ovulating as soon as four to six years old. The females are diestrous , coming into heat in late summer and around February, yet

4902-416: The largest tusks typically dominate social groups. Tusks are also used to form and maintain holes in the ice and aid the walrus in climbing out of water onto ice. Tusks were once thought to be used to dig out prey from the seabed, but analyses of abrasion patterns on the tusks indicate they are dragged through the sediment while the upper edge of the snout is used for digging. While the dentition of walruses

4988-486: The latter follows the other into the water, where the bear is at a disadvantage. Polar bear–walrus battles are often extremely protracted and exhausting, and bears have been known to break away from the attack after injuring a walrus. Orcas regularly attack walruses, although walruses are believed to have successfully defended themselves via counterattack against the larger cetacean. However, orcas have been observed successfully attacking walruses with few or no injuries. In

Soon after, the children's cartoon "Antje, Tiger und Bär" aired on German television featuring a blue walrus protagonist based on Antje and designed by children's author Janosch . In 2013, Tierpark Hagenbeck gained a male and three female walruses from Moscow . Inside

5160-462: The males are fertile only around February; the potential fertility of this second period is unknown. Breeding occurs from January to March, peaking in February. Males aggregate in the water around ice-bound groups of estrous females and engage in competitive vocal displays. The females join them and copulate in the water. Gestation lasts 15 to 16 months. The first three to four months are spent with

Managers of the zoo reported that more than two dozen of the long-tailed Indian monkeys had been caught by policemen, firemen, zoo keepers and schoolchildren. In 1976, the zoo acquired a female Pacific walrus which Hagenbeck named Antje after his sister. Antje became

In March 2021, a single walrus, nicknamed Wally the Walrus , was sighted at Valentia Island , Ireland , far south of its typical range, potentially due to having fallen asleep on an iceberg that then drifted south towards Ireland. Days later, a walrus, thought to be the same animal, was spotted on the Pembrokeshire coast, Wales . In June 2022,

5418-516: The pack ice has reached unusually low levels in several recent years. The walrus relies on this ice while giving birth and aggregating in the reproductive period. Thinner pack ice over the Bering Sea has reduced the amount of resting habitat near optimal feeding grounds. This more widely separates lactating females from their calves, increasing nutritional stress for the young and lower reproductive rates. Reduced coastal sea ice has also been implicated in

During the partition of Germany between 1945 and 1990, the Port of Hamburg lost much of its hinterland and consequently many of its trading connections. However, since German reunification , the fall of the Iron Curtain and European enlargement , Hamburg has made substantial ground as one of Europe's prime logistics centres and as one of

5676-493: The sea bottom, searching and identifying prey with its sensitive vibrissae and clearing the murky bottoms with jets of water and active flipper movements. The walrus sucks the meat out by sealing its powerful lips to the organism and withdrawing its piston-like tongue rapidly into its mouth, creating a vacuum. The walrus palate is uniquely vaulted, enabling effective suction. The diet of the Pacific walrus consist almost exclusively of benthic invertebrates (97 percent). Aside from

For example, the Old Norse word hrosshvalr means 'horse-whale' and is thought to have been passed in an inverted form to both Dutch and the dialects of northern Germany as walros and Walross . An alternative theory is that it comes from the Dutch words wal 'shore' and reus 'giant'. The species name rosmarus

5934-468: The subfamilies Imagotariinae, Dusignathinae and Odobeninae. The key distinguishing feature was the development of a squirt/suction feeding mechanism; tusks are a later feature specific to Odobeninae, of which the modern walrus is the last remaining ( relict ) species. Two subspecies of walrus are widely recognized: the Atlantic walrus, O. r. rosmarus (Linnaeus, 1758) and the Pacific walrus, O. r. divergens (Illiger, 1815). Fixed genetic differences between

6020-461: The sun and the moon from an evil spirit by seducing his daughter, the angry father throws the daughter from a high cliff and, as she drops into the water, she turns into a walrus . According to various legends, the tusks are formed either by the trails of mucus from the weeping girl or her long braids. This myth is possibly related to the Chukchi myth of the old walrus-headed woman who rules the bottom of

6106-686: The three walrus subspecies are listed as "least-concern" by the IUCN , while the third is "data deficient". The Pacific walrus is not listed as "depleted" according to the Marine Mammal Protection Act nor as "threatened" or "endangered" under the Endangered Species Act . The Russian Atlantic and Laptev Sea populations are classified as Category 2 (decreasing) and Category 3 (rare) in the Russian Red Book . Global trade in walrus ivory

6192-428: The two elephant seals . Walruses maintain such a high body weight because of the blubber stored underneath their skin. This blubber keeps them warm and the fat provides energy to the walrus. The walrus's body shape shares features with both sea lions ( eared seals : Otariidae) and seals ( true seals : Phocidae). As with otariids, it can turn its rear flippers forward and move on all fours; however, its swimming technique

6278-429: The vibrissae, the walrus is sparsely covered with fur and appears bald. Its skin is highly wrinkled and thick, up to 10 cm (4 in) around the neck and shoulders of males. The blubber layer beneath is up to 15 cm (6 in) thick. Young walruses are deep brown and grow paler and more cinnamon-colored as they age. Old males, in particular, become nearly pink. Because skin blood vessels constrict in cold water,

6364-494: The walrus a characteristic whiskered appearance. There can be 400 to 700 vibrissae in 13 to 15 rows reaching 30 cm (12 in) in length, though in the wild they are often worn to much shorter lengths due to constant use in foraging. The vibrissae are attached to muscles and are supplied with blood and nerves, making them highly sensitive organs capable of differentiating shapes 3 mm ( 1 ⁄ 8  in) thick and 2 mm ( 3 ⁄ 32  in) wide. Aside from

6450-664: The walrus also appears in the popular cultures of peoples with little direct experience with the animal, particularly in English children's literature. Perhaps its best-known appearance is in Lewis Carroll 's whimsical poem " The Walrus and the Carpenter " that appears in his 1871 book Through the Looking-Glass . In the poem, the eponymous antiheroes use trickery to consume a great number of oysters . Although Carroll accurately portrays

6536-538: The walrus as the ros marus , probably a Latinization of morž , and this was adopted by Linnaeus in his binomial nomenclature . The coincidental similarity between morse and the Latin word morsus ('a bite') supposedly contributed to the walrus's reputation as a "terrible monster". The compound Odobenus comes from odous ( Greek for 'teeth') and baino (Greek for 'walk'), based on observations of walruses using their tusks to pull themselves out of

6622-420: The walrus can appear almost white when swimming. As a secondary sexual characteristic , males also acquire significant nodules, called "bosses", particularly around the neck and shoulders. The walrus has an air sac under its throat which acts like a flotation bubble and allows it to bob vertically in the water and sleep. The males possess a large baculum (penis bone), up to 63 cm (25 in) in length,

6708-414: The walrus with the lowest reproductive rate of any pinniped. The rest of the year (late summer and fall), walruses tend to form massive aggregations of tens of thousands of individuals on rocky beaches or outcrops. The migration between the ice and the beach can be long-distance and dramatic. In late spring and summer, for example, several hundred thousand Pacific walruses migrate from the Bering Sea into

6794-508: The walruses began to repopulate. By 2018, the population had increased to an estimated 5,503 walruses in the Svalbard area. The walrus plays an important role in the religion and folklore of many Arctic peoples. Skin and bone are used in some ceremonies, and the animal appears frequently in legends. For example, in a Chukchi version of the widespread myth of the Raven , in which Raven recovers

6880-631: The water. The term divergens in Latin means 'turning apart', referring to their tusks. The Inuttitut term for the creature is aivik , similar to the Inuktitut word: aiviq ᐊᐃᕕᖅ. The walrus is a mammal in the order Carnivora . It is the sole surviving member of the family Odobenidae, one of three lineages in the suborder Pinnipedia along with true seals ( Phocidae ) and eared seals ( Otariidae ). While there has been some debate as to whether all three lineages are monophyletic , i.e. descended from

6966-607: The world's largest and busiest sea ports. In 2022, the German government let the Chinese state-owned COSCO Shipping take a stake in ownership of the port. Deepening of the river Elbe for large vessels is controversial for ecological reasons. In part due to cooperation with Lower Saxony and Bremen to build a new container port ( JadeWeserPort ) in the deep waters of Jadebusen in Wilhelmshaven , Hamburg withdrew from this plan after

7052-448: The world. Since 1888, the HADAG runs a scheduled ferry service across various parts of the port and the Elbe. The Free Port (Freihafen), established on 15 October 1888, enabled traders to ship and store goods without going through customs and further enhanced Hamburg's position in sea trade with neighbouring countries. It was permanently closed on 1 January 2013. The Moldauhafen has

7138-443: The zoo into hard times. During World War I many of the keepers were drafted into the German army. Because the military had taken horses from civilians for use at the front, many of Hagenbeck's animals were rented out for use as draught animals for hauling coal and wood on home deliveries. It was not unusual to see elephants and trained bears hitched up to heavy wagons. After the war, the zoo closed for two years as Germany entered into

7224-406: Was not true of all extinct walruses, the most prominent feature of the living species is its long tusks. These are elongated canines , which are present in both male and female walruses and can reach a length of 1 m (3 ft 3 in) and weigh up to 5.4 kg (12 lb). Tusks are slightly longer and thicker among males, which use them for fighting, dominance and display; the strongest males with

7310-525: Was the hub destination of the Hamburg America Line , that assured the Nazi Party a connection to the United States for the import of oil and steel, and the export of manufactured goods from Germany thanks to container ships. The shipping line Hamburg-Amerikanische Packetfahrt-Aktien-Gesellschaft ( HAPAG ) gave the name to the so-called shipping company based in Hamburg which used to run the trades of goods on this route. In 1970, along with Norddeutscher Lloyd ,

7396-511: Was wiped out after Norse settlement around 1213–1330 AD. An isolated population is restricted, year-round, to the central and western regions of the Laptev Sea , from the eastern Kara Sea to the westernmost regions of the East Siberian Sea . The current population of these Laptev walruses has been estimated at between 5-10,000. Even though walruses can dive to depths beyond 500 meters, they spend most of their time in shallow waters (and
