80-765: Pangolins , sometimes known as scaly anteaters , are mammals of the order Pholidota ( / f ɒ l ɪ ˈ d oʊ t ə / ). The one extant family, the Manidae , has three genera: Manis , Phataginus , and Smutsia . Manis comprises four species found in Asia, while Phataginus and Smutsia include two species each, all found in sub-Saharan Africa. These species range in size from 30 to 100 cm (12 to 39 in). Several extinct pangolin species are also known. In September 2023, nine species were reported. Pangolins have large, protective keratin scales, similar in material to fingernails and toenails, covering their skin; they are
160-1077: A ball (" volvation "). Arboreal pangolins live in hollow trees, whereas the ground-dwelling species dig tunnels to a depth of 3.5 m (11 ft). Some pangolins walk with their front claws bent under the foot pad, although they use the entire foot pad on their rear limbs. Furthermore, some exhibit a bipedal stance for some behavior, and may walk a few steps bipedally. Pangolins are also good swimmers. Pangolins are insectivorous . Most of their diet consists of various species of ants and termites and may be supplemented by other insects, especially larvae. They are somewhat particular and tend to consume only one or two species of insects, even when many species are available. A pangolin can consume 140 to 200 g (5 to 7 oz) of insects per day. Pangolins are an important regulator of termite populations in their natural habitats. Pangolins have very poor vision . They also lack teeth. They rely heavily on smell and hearing , and they have other physical characteristics to help them eat ants and termites. Their skeletal structure

In general appearance, the Zorrillo resembles a polecat, but it is rather larger and much thicker in proportion. Conscious of its power, it roams by day about the open plain and fears neither dog nor man. If a dog is urged to the attack, its courage is instantly checked by a few drops of the fetid oil, which brings on violent sickness and running at
320-728: A dormant stage. Over winter, multiple females (as many as 12) huddle together; males often den alone. Often, the same winter den is repeatedly used. Although they have excellent senses of smell and hearing, they have poor vision, being unable to see objects more than about 3 m (10 ft) away, making them vulnerable to death by road traffic . They are short-lived; their lifespan in the wild can reach seven years, with an average of six years. In captivity, they may live for up to 10 years. Skunks mate in early spring and are polygynous (that is, successful males are uninhibited from mating with additional females). Before giving birth (usually in May),
400-409: A genetic dysfunction, making them extremely fragile. They are susceptible to diseases such as pneumonia and the development of ulcers in captivity, complications that can lead to an early death. In addition, pangolins rescued from illegal trade often have a higher chance of being infected with parasites such as intestinal worms , further lessening their chance for rehabilitation and reintroduction to
480-419: A noxious-smelling chemical from glands near the anus, similar to the spray of a skunk . They have short legs, with sharp claws which they use for burrowing into ant and termite mounds and for climbing. The tongues of pangolins are extremely long, and like those of the giant anteater and the tube-lipped nectar bat , the root of the tongue is not attached to the hyoid bone but is in the thorax between
560-427: A skunk finding its way into a garage or basement where pet food is kept. Skunks commonly dig holes in lawns in search of grubs and worms. Skunks use their long claws to break apart rotting logs to find insects that live within them. They also use those claws to help dig for insects, which leaves behind pits, which are easy signs of foraging. The claws also help with pinning down live and active prey. Skunks are one of
640-666: A study found that it is "not too late" to establish conservation efforts for Philippine pangolins ( Manis culionensis ), a species that is only found on the island province of Palawan. Taiwan is one of the few conservation grounds for pangolins in the world after the country enacted the 1989 Wildlife Conservation Act. The introduction of Wildlife Rehabilitation Centers in places like Luanshan ( Yanping Township ) in Taitung and Xiulin townships in Hualien became important communities for protecting pangolins and their habitats and has greatly improved
720-612: A verb, skunk is used to describe the act of overwhelmingly defeating an opponent in a game or competition. Skunk is also used to refer to certain strong-smelling strains of Cannabis whose smell has been compared to that of a skunk's spray. Skunk species vary in size from about 15.6 to 37 in (40 to 94 cm) long and in weight from about 1.1 lb (0.50 kg) (spotted skunks) to 18 lb (8.2 kg) ( hog-nosed skunks ). They have moderately elongated bodies with relatively short, well-muscled legs and long front claws for digging. They have five toes on each foot. Although

Mammals are characterized by the presence of milk -producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair , and three middle ear bones . These characteristics distinguish them from reptiles and birds , from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,400 extant species of mammals have been described and divided into 27 orders . The largest orders of mammals, by number of species , are

Some species, such as the tree pangolin , use their strong, prehensile tails to hang from tree branches and strip away bark from the trunk, exposing insect nests inside. Pangolins are solitary and meet only to have sex, with mating typically taking place at night after

Mammal classification has been through several revisions since Carl Linnaeus initially defined the class, and at present , no classification system is universally accepted. McKenna & Bell (1997) and Wilson & Reeder (2005) provide useful recent compendiums. Simpson (1945) provides systematics of mammal origins and relationships that had been taught universally until
1120-664: Is protective of her kits, spraying at any sign of danger. The male plays no part in raising the young. Skunks are omnivorous , eating both plant and animal material and changing their diets as the seasons change. They eat insects, larvae , earthworms , grubs , rodents , lizards, salamanders , frogs, snakes, birds, moles , and eggs . They also commonly eat berries , roots , leaves , grasses, fungi and nuts . In settled areas, skunks also seek garbage left by humans. Less often, skunks may be found acting as scavengers , eating bird and rodent carcasses left by cats or other animals. Pet owners, particularly those of cats, may experience
1200-409: Is rare for a healthy skunk to bite a human, though a tame skunk whose scent glands have been removed (usually on behalf of those who will keep it as a pet) may defend itself by biting. There are, however, few recorded incidents of skunks biting humans. Skunk bites in humans can result in infection with the rabies virus. The Centers for Disease Control (CDC) recorded 1,494 cases of rabies in skunks in
1280-465: Is reported in Nigeria , where the animal is on the verge of extinction due to overexploitation . The overexploitation comes from hunting pangolins for game meat and the reduction of their forest habitats due to deforestation caused by timber harvesting . The pangolin are hunted as game meat for both medicinal purposes and food consumption. The nucleic acid sequence of a specific receptor-binding domain of

They use their powerful front claws to dig into trees, soil, and vegetation to find prey, then proceed to use their long tongues to probe inside the insect tunnels and to retrieve their prey. The structure of their tongue and stomach is key to aiding pangolins in obtaining and digesting insects. Their saliva is sticky, causing ants and termites to stick to their long tongues when they are hunting through insect tunnels. Without teeth, pangolins cannot also chew; but while foraging , they ingest small stones ( gastroliths ), which accumulate in their stomachs to help to grind up ants. This part of their stomach
1440-426: Is the viviparous placental mammals , so named for the temporary organ ( placenta ) used by offspring to draw nutrition from the mother during gestation . Most mammals are intelligent , with some possessing large brains, self-awareness , and tool use . Mammals can communicate and vocalize in several ways, including the production of ultrasound , scent marking , alarm signals , singing , echolocation ; and, in
1520-472: Is to a skunk's advantage to warn possible predators off without expending scent: black and white aposematic warning coloration aside, threatened skunks will go through an elaborate routine of hisses, foot-stamping, and tail-high deimatic or threat postures before resorting to spraying. Skunks usually do not spray other skunks, except among males in the mating season. If they fight over den space in autumn, they do so with teeth and claws. Most predators of

In the 21st century, the main uses of pangolin scales are quackery practices based on unproven claims the scales dissolve blood clots , promote blood circulation, or help lactating women secrete milk. The supposed health effects of pangolin meat and scales claimed by folk medicine practitioners are based on their consumption of ants, long tongues, and protective scales.

Most pangolins are nocturnal animals which use their well-developed sense of smell to find insects. The long-tailed pangolin is also active by day, while other species of pangolins spend most of the daytime sleeping, curled up into
2640-546: The Americas, such as wolves , foxes , and badgers , seldom attack skunks, presumably out of fear of being sprayed. The exceptions are reckless predators whose attacks fail once they are sprayed, dogs, and the great horned owl , which is the skunk's only regular predator. In one case, the remains of 57 striped skunks were found in a single great horned owl nest. Skunks are common in suburban areas, and domestic dogs are often sprayed by skunks. There are many misconceptions about

The IUCN SSC Pangolin Specialist Group launched a global action plan to conserve pangolins, dubbed "Scaling up Pangolin Conservation", in July 2014. This action plan aims to improve all aspects of pangolin conservation with an added emphasis on combating poaching and trafficking of the animal while educating communities on its importance. Another suggested approach to fighting pangolin (and general wildlife) trafficking consists in "following

They are made of keratin , the same material from which human fingernails and tetrapod claws are made, and are structurally and compositionally very different from the scales of reptiles. The pangolin's scaled body is comparable in appearance to a pine cone . It can curl up into a ball when threatened, with its overlapping scales acting as armor , while it protects its face by tucking it under its tail. The scales are sharp, providing extra defense from predators. Pangolins can emit

The earliest-known synapsid satisfying Kemp's definitions is Tikitherium , dated 225 Ma , so the appearance of mammals in this broader sense can be given this Late Triassic date. However, this animal may have actually evolved during the Neogene. As of the early 21st century, molecular studies based on DNA analysis have suggested new relationships among mammal families. Most of these findings have been independently validated by retrotransposon presence/absence data . Classification systems based on molecular studies reveal three major groups or lineages of placental mammals— Afrotheria , Xenarthra and Boreoeutheria —which diverged in

Some species, such as Manis pentadactyla have become commercially extinct in certain ranges as a result of overhunting. In November 2010, pangolins were added to the Zoological Society of London 's list of evolutionarily distinct and endangered mammals. All eight species of pangolin are assessed as threatened by
5360-414: The primary predators of the honeybee , relying on their thick fur to protect them from stings. The skunk scratches at the front of the beehive and eats the guard bees that come out to investigate. Mother skunks are known to teach this behavior to their young. Skunks are notorious for their anal scent glands, which they can use as a defensive weapon . They are similar to, though much more developed than,
5440-716: The primary source of food for humans. This led to a major restructuring of human societies from nomadic to sedentary, with more co-operation among larger and larger groups, and ultimately the development of the first civilizations . Domesticated mammals provided, and continue to provide, power for transport and agriculture, as well as food ( meat and dairy products ), fur , and leather . Mammals are also hunted and raced for sport, kept as pets and working animals of various types, and are used as model organisms in science. Mammals have been depicted in art since Paleolithic times, and appear in literature, film, mythology, and religion. Decline in numbers and extinction of many mammals
5520-465: The removal of skunk odor, including the pervasive idea that tomato juice will neutralize the odor. These household remedies are ineffective, and only appear to work due to olfactory fatigue . In 1993, The American chemist Paul Krebaum has developed a formula that chemically neutralizes skunk spray by changing the odor-causing thiols into odorless acids, which is endorsed by the Humane Society of
5600-435: The scales are soft and white. After several days, they harden and darken to resemble those of an adult pangolin. During the vulnerable stage, the mother stays with her offspring in the burrow, nursing it, and wraps her body around it if she senses danger. The young cling to the mother's tail as she moves about, although, in burrowing species, they remain in the burrow for the first 2–4 weeks of life. At one month, they first leave
5680-580: The scales as a cure for people crying hysterically during the night. During the Tang dynasty , a recipe for expelling evil spirits with a formulation of scales, herbs, and minerals appeared in 682, and in 752 CE the idea that pangolin scales could also stimulate milk secretion in lactating women, one of the main uses today, was recommended in the Wai Tai Mi Yao ("Arcane Essentials from the Imperial Library"). In
5760-600: The scales of a pangolin can help prevent pneumonia. Pangolin scales have also been used for medicinal purposes in Malaysia, Indonesia and northern Myanmar. Indigenous people in southern Palawan , Philippines, have held the belief that elders could avoid prostate illnesses by wearing belts made with the scales. As a result of increasing threats to pangolins, mainly in the form of illegal, international trade in pangolin skin, scales, and meat, these species have received increasing conservation attention in recent years. As of January 2020,
5840-464: The scent glands allow them to spray with a high degree of accuracy, as far as 3 m (10 ft). The spray can also cause irritation and even temporary blindness, and is sufficiently powerful to be detected by a human nose up to 5.6 km (3.5 miles) downwind. Their chemical defense is effective, as illustrated by this extract from Charles Darwin 's 1839 book The Voyage of the Beagle : We saw also
5920-602: The survival of pangolins. These centers work with local aboriginal tribes and forest police in the National Police Agency to prevent poaching, trafficking, and smuggling of pangolins, especially to black markets in China. These centers have also helped to reveal the causes of death and injury among Taiwan's pangolin population. Today, Taiwan has the highest population density of pangolins in the world. Mammals A mammal (from Latin mamma 'breast')
6000-454: The tail of a Fox; it carries it curled back like that of a Squirrel. It is more white than black; and, at the first glance, you would say, especially when it walks, that it ought to be called Jupiter's little dog. But it is so stinking and casts so foul an odor, that it is unworthy of being called the dog of Pluto. No sewer ever smelled so bad. I would not have believed it if I had not smelled it myself. Your heart almost fails you when you approach
6080-409: The testing which suggested that pangolins were a potential host for the virus was flawed, when genetic analysis showed that the spike protein and its binding to receptors in pangolins had minimal effect from the virus, and therefore were not likely mechanisms for COVID-19 infections in humans. In 2020, two novel RNA viruses distantly related to pestiviruses and coltiviruses have been detected in
6160-537: The therians; as fossils of all three genera are dated about 167 million years ago in the Middle Jurassic , this is a reasonable estimate for the appearance of the crown group. T. S. Kemp has provided a more traditional definition: " Synapsids that possess a dentary – squamosal jaw articulation and occlusion between upper and lower molars with a transverse component to the movement" or, equivalently in Kemp's view,
6240-698: The two are not closely related; they have merely undergone convergent evolution . Pangolins are threatened by poaching (for their meat and scales, which are used in traditional medicine ) and heavy deforestation of their natural habitats, and are the most trafficked mammals in the world. As of January 2020, there are eight species of pangolin whose conservation status is listed in the threatened tier. Three ( Manis culionensis , M. pentadactyla and M. javanica ) are critically endangered, three ( Phataginus tricuspis , Manis crassicaudata and Smutsia gigantea ) are endangered and two ( Phataginus tetradactyla and Smutsia temminckii ) are vulnerable on
6320-572: The wild. The idea of farming pangolins to reduce the number being illegally trafficked is being explored with little success. The third Saturday in February is promoted as World Pangolin Day by the conservation NPO Annamiticus. World Pangolin Day has been noted for its effectiveness in generating awareness about pangolins. In 2017, Jackie Chan made a public service announcement called WildAid : Jackie Chan & Pangolins (Kung Fu Pangolin) . In December 2020,
6400-464: Was suggested as a vector for human transmission. However, whole-genome comparison found that the pangolin and human coronaviruses share only up to 92% of their RNA. Ecologists worried that the early speculation about pangolins being the source may have led to mass slaughters, endangering them further, which was similar to what happened to Asian palm civets during the SARS outbreak. It was later proved that
