Pangolins have large, protective keratin scales, similar in material to fingernails and toenails, covering their skin; they are the only known mammals with this feature. Depending on the species, they live in hollow trees or burrows. Pangolins are nocturnal, and their diet consists of mainly ants and termites, which they capture using their long tongues. They tend to be solitary animals, meeting only to mate and produce a litter of one to three offspring, which they raise for about two years. Pangolins superficially resemble armadillos, though the two are not closely related; they have undergone convergent evolution.

Description

File:Pangolin scale histology.jpg

The physical appearance of a pangolin is marked by large, hardened, overlapping, plate-like scales, which are soft on newborn pangolins, but harden as the animal matures.{{Cite journal |last1=Li |first1=Hui-Ming |last2=Liu |first2=Ping |last3=Zhang |first3=Xiu-Juan |last4=Li |first4=Lin-Miao |last5=Jiang |first5=Hai-Ying |last6=Yan |first6=Hua |last7=Hou |first7=Fang-Hui |last8=Chen |first8=Jin-Ping|display-authors=4 |date=2020-09-03 |title=Combined proteomics and transcriptomics reveal the genetic basis underlying the differentiation of skin appendages and immunity in pangolin |journal=Scientific Reports |language=en |volume=10 |issue=1 |page=14566 |doi=10.1038/s41598-020-71513-w |pmid=32884035 |issn=2045-2322|pmc=7471334 |bibcode=2020NatSR..1014566L }} 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.{{Cite journal |last=Spearman |first=R.I.C. |title=On the nature of the horny scales of the pangolin |journal=Zoological Journal of the Linnean Society |publisher=Oxford University Press |location=Oxfordshire, England |volume=46 |issue=310 |pages=267–273 |year=2008 |doi=10.1111/j.1096-3642.1967.tb00508.x}} 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.{{Cite journal |last1=Wang |first1=Bin |last2=Yang |first2=Wen |last3=Sherman |first3=Vincent R. |last4=Meyers |first4=Marc A. |title=Pangolin armor: Overlapping, structure, and mechanical properties of the keratinous scales |journal=Acta Biomaterialia |publisher=Elsevier |location=Oxfordshire, England |volume=41 |pages=60–74 |year=2016 |doi=10.1016/j.actbio.2016.05.028 |pmid=27221793}}

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 the sternum and the trachea.{{cite journal |last=Chan |first=Lap-Ki |title=Extrinsic Lingual Musculature of Two Pangolins (Pholidota: Manidae) |journal=Journal of Mammalogy |publisher=Oxford University Press |location=Oxfordshire, England |volume=76 |issue=2 |pages=472–480 |year=1995 |doi=10.2307/1382356 |jstor=1382356}} Large pangolins can extend their tongues as much as {{convert|40|cm|in|abbr=on}}, with a diameter of only about {{convert|0.5|cm|in|frac=5|abbr=on}}.

The long-tailed pangolin is also active by day, while other species of pangolins spend most of the daytime sleeping, curled up into a ball ("volvation").{{cite book |editor-first=Arnoldo |editor-last=Mondadori |title=Great Book of the Animal Kingdom |location=New York City |publisher=Arch Cape Press |year=1988 |page=252 |isbn=978-0517667910}}

Arboreal pangolins live in hollow trees, whereas the ground-dwelling species dig tunnels to a depth of {{convert|3.5|m|ft|abbr=on}}.

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.{{cite journal |first1=Rajesh K. |last1=Mohapatra |first2=Sudarsen |last2=Panda |year=2014 |title=Behavioural descriptions of Indian pangolins (Manis crassicaudata) in captivity. |journal=International Journal of Zoology |publisher=Wiley-Blackwell |location=London, England |volume=2014 |pages=1–7 |doi=10.1155/2014/795062 |doi-access=free}} Pangolins are also good swimmers.

=Diet=

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 {{convert|140|to|200|g|oz|frac=4|abbr=on}} of insects per day.{{cite web |url=http://bioweb.uwlax.edu/bio203/s2012/grosshue_crai/diet.htm |title=Rollin' With the Pangolin – Diet |first=Craig |last=Grosshuesch |year=2012 |publisher=University of Wisconsin–La Crosse |location=La Crosse, Wisconsin |archive-url=https://web.archive.org/web/20141223020558/http://bioweb.uwlax.edu/bio203/s2012/grosshue_crai/diet.htm |archive-date=23 December 2014 |url-status=live}} Pangolins are an important regulator of termite populations in their natural habitats.{{cite journal |doi=10.7717/peerj.4140 |pmid=29302388 |pmc=5742527 |title=Transcriptomic analysis identifies genes and pathways related to myrmecophagy in the Malayan pangolin (Manis javanica) |journal=PeerJ |publisher=O'Reilly Media |location=Corte Madera, California |volume=5 |pages=e4140 |year=2017 |last1=Ma |first1=Jing-E |last2=Li |first2=Lin-Miao |last3=Jiang |first3=Hai-Ying |last4=Zhang |first4=Xiu-Juan |last5=Li |first5=Juan |last6=Li |first6=Guan-Yu |last7=Yuan |first7=Li-Hong |last8=Wu |first8=Jun |last9=Chen |first9=Jin-Ping |doi-access=free }}

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 is sturdy and they have strong front legs used for tearing into termite mounds.{{Cite book |title=Xenarthra and Pholidota (Armadillos, Anteaters, Sloths and Pangolins) |last1=Rose |first1=K.

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;{{cite book |first=Lee |last=Gutteridge |title=The South African Bushveld: A Field Guide from the Waterberg |url={{GBurl|id=Dvk4ogj3SxcC|pg=PT36}} |year=2008 |publisher=30° South Publishers |location=Pinetown, South Africa |isbn=978-1-920143-13-8 |page=36}} but while foraging, they ingest small stones (gastroliths), which accumulate in their stomachs to help to grind up ants.{{cite book |title=Wildlife of the World |url={{GBurl|id=qqFFCgAAQBAJ|p=215}} |year=2015 |publisher=Dorling Kindersley |location=London, England |isbn=978-1-4654-4959-7 |page=215}} This part of their stomach is called the gizzard, and it is also covered in keratinous spines.{{Cite journal |last1=Davit-Béal |first1=Tiphaine |last2=Tucker |first2=Abigail S. |last3=Sire |first3=Jean-Yves |date=1 April 2009 |title=Loss of teeth and enamel in tetrapods: fossil record, genetic data and morphological adaptations |journal=Journal of Anatomy |publisher=John Wiley & Sons |location=New York City |volume=214 |issue=4 |pages=477–501 |doi=10.1111/j.1469-7580.2009.01060.x |pmid=19422426 |pmc=2736120}} These spines further aid in the grinding up and digestion of the pangolin's prey.

Pangolins are solitary and meet only to have sex, with mating typically taking place at night after the male and female pangolin meet near a watering hole. Males are larger than females, weighing up to 40% more. While the mating season is not defined, they typically mate once each year, usually during the summer or autumn. Rather than the males seeking out the females, males mark their location with urine or feces and the females find them. If competition over a female occurs, the males use their tails as clubs to fight for the opportunity to mate with her.{{cite web |url=https://bioweb.uwlax.edu/bio203/s2012/grosshue_crai/reproduction.htm |title=Rollin' With the Pangolin – Reproduction |first=Craig |last=Grosshuesch |year=2012 |publisher=University of Wisconsin–La Crosse |archive-url=https://web.archive.org/web/20141223040747/http://bioweb.uwlax.edu/bio203/s2012/grosshue_crai/reproduction.htm |archive-date=23 December 2014 |url-status=dead}}

Weight at birth is {{convert|80|to|450|g|oz|frac=4|abbr=on}}, and the average length is {{convert|150|mm|in|frac=4|abbr=on}}. At the time of birth, 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 two to four weeks of life. At one month, they first leave the burrow riding on the mother's back. Weaning takes place around three months of age, when the young begin to eat insects in addition to nursing. At two years of age, the offspring are sexually mature and are abandoned by the mother.{{cite book |last=Dickman |first=Christopher R. |editor-last=MacDonald |editor-first=D. |year=1984 |title=The Encyclopedia of Mammals |publisher=Facts on File |location=New York |pages=[https://archive.org/details/encyclopediaofma00mals_0/page/780 780–781] |isbn=978-0-87196-871-5 |url-access=registration |url=https://archive.org/details/encyclopediaofma00mals_0/page/780}}

{{see also|Pholidotamorpha}}

The order Pholidota was long considered to be the sister taxon to Xenarthra (neotropical anteaters, sloths, and armadillos), but recent genetic evidence indicates their closest living relatives are the carnivorans, with which they form a clade, the Ferae.{{cite journal |name-list-style=vanc |display-authors=2 |last1=Murphy |first1=William J. |last2=Eizirik |first2=Eduardo |last3=O'Brien |first3=Stephen J. |last4=Madsen |first4=Ole |last5=Scally |first5=Mark |last6=Douady |first6=Christophe J. |last7=Teeling |first7=Emma |last8=Ryder |first8=Oliver A. |last9=Stanhope |first9=Michael J. |last10=de Jong |first10=Wilfried W. |last11=Springer |first11=Mark S. |date=14 December 2001 |title=Resolution of the Early Placental Mammal Radiation Using Bayesian Phylogenetics |journal=Science |doi=10.1126/science.1067179 |pmid=11743200 |bibcode=2001Sci...294.2348M |volume=294 |issue=5550 |pages=2348–2351 |s2cid=34367609}}{{cite journal |author=Amrine-Madsen, H. |author2=Koepfli, K.P. |author3=Wayne, R.K. |author4=Springer, M.S. |year=2003 |title=A new phylogenetic marker, apolipoprotein B, provides compelling evidence for eutherian relationships |journal=Molecular Phylogenetics and Evolution |volume=28 |issue=2 |pages=225–240 |doi=10.1016/S1055-7903(03)00118-0 |pmid=12878460|bibcode=2003MolPE..28..225A }}{{cite journal |first1=Robin |last1=Beck |first2=Olaf |last2=Bininda-Emonds |first3=Marcel |last3=Cardillo |first4=Fu-Guo |last4=Liu |first5=Andy |last5=Purvis |title=A higher-level MRP supertree of placental mammals |journal=BMC Evolutionary Biology |publisher=BioMed Central |location=London, England |date=2006 |volume=6 |issue=1 |pages=93 |doi=10.1186/1471-2148-6-93 |pmid=17101039 |pmc=1654192 |doi-access=free }}{{cite journal |last1=Du Toit |first1=Z. |last2=Grobler |first2=J.

==Among Manidae==

The first dichotomy in the phylogeny of extant Manidae separates Asian pangolins (Manis) from African pangolins (Smutsia and Phataginus). Within the former, Manis pentadactyla is the sister group to a clade comprising M. crassicaudata and M. javanica. Within the latter, a split separates the large terrestrial African pangolins of the genus Smutsia from the small arboreal African pangolins of the genus Phataginus.{{Cite journal |last1=Gaubert |first1=Philippe |last2=Antunes |first2=Agostinho |last3=Meng |first3=Hao |last4=Miao |first4=Lin |last5=Peigné |first5=Stéphane |last6=Justy |first6=Fabienne |last7=Njiokou |first7=Flobert |last8=Dufour |first8=Sylvain |last9=Danquah |first9=Emmanuel |last10=Alahakoon |first10=Jayanthi |last11=Verheyen |first11=Erik |date=11 May 2018 |title=The Complete Phylogeny of Pangolins: Scaling Up Resources for the Molecular Tracing of the Most Trafficked Mammals on Earth |journal=Journal of Heredity |language=en |volume=109 |issue=4 |pages=347–359 |doi=10.1093/jhered/esx097 |pmid=29140441 |doi-access=}}

The first record of pangolin scales occurs in Ben Cao Jinji Zhu ("Variorum of Shennong's Classic of Materia Medica", 500 CE), which recommends pangolin scales for protection against ant bites; burning the scales as a cure for people crying hysterically during the night.{{cite book |last1=Xing |first1=S. |title=Pangolins: Science, Society and Conservation |last2=Bonebrake |first2=T.

In the Song dynasty, the notion of penetrating and clearing blockages was emphasized in the Taiping sheng hui fan ("Formulas from Benevolent Sages Compiled During the Era of Peace and Tranquility"), compiled by Wang Huaiyin in 992.

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.

The official pharmacopoeia of the People's Republic of China included Chinese pangolin scales as an ingredient in TCM formulations. Pangolins were removed from the pharmacopoeia starting from the first half of 2020.{{cite web |last1=Maron |first1=Dina Fine |url=https://www.nationalgeographic.com/animals/2020/06/pangolins-receive-new-protections-traditional-medicine-in-china/ |archive-url=https://web.archive.org/web/20200610111656/https://www.nationalgeographic.com/animals/2020/06/pangolins-receive-new-protections-traditional-medicine-in-china/ |url-status=dead |archive-date=10 June 2020 |title=Pangolins receive surprising lifeline with new protections in China |date=9 June 2020 |website=National Geographic |access-date=12 June 2020}} Although pangolin scales have been removed from the list of raw ingredients, the scales are still listed as a key ingredient in various medicines.{{Cite news |date=2020 |title=Did China really ban the pangolin trade?

Pangolin parts are also used for medicinal purposes in other Asian countries such as India, Nepal and Pakistan. In some parts of India and Nepal, locals believe that wearing the scales of a pangolin can help prevent pneumonia.{{Cite book |chapter-url={{GBurl|id=zey_DwAAQBAJ|p=228}} |title=Pangolins: Science, Society and Conservation |publisher=Academic Press |isbn=978-0-12-815506-6 |publication-date=2019-11-23 |pages=228 |language=en |chapter=Meat and medicine: historic and contemporary use in Asia}} Pangolin scales have also been used for medicinal purposes in Malaysia, Indonesia and northern Myanmar.

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.{{Cite journal|last=Shibaike|first=Takumi|date=2021|title=Small NGOs and Agenda-Setting in Global Conservation Governance: The Case of Pangolin Conservation|journal=Global Environmental Politics|volume=22 |issue=2 |pages=45–69|doi=10.1162/glep_a_00623|s2cid=240588135|issn=1526-3800|doi-access=free}} {{As of|January 2020}}, the IUCN considered all eight species of pangolin on its Red List of Threatened Species as threatened. 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.{{cite web |title=Action Plan |website=www.pangolinsg.org |url=http://www.pangolinsg.org/members-work/action-plan/ |access-date=15 September 2016 |archive-date=10 July 2017 |archive-url=https://web.archive.org/web/20170710234327/http://www.pangolinsg.org/members-work/action-plan/ |url-status=dead }} Another suggested approach to fighting pangolin (and general wildlife) trafficking consists in "following the money" rather than "the animal", which aims to disrupt smugglers' profits by interrupting money flows. Financial intelligence gathering could thus become a key tool in protecting these animals, although this opportunity is often overlooked. In 2018, a Chinese NGO launched the Counting Pangolins movement, calling for joint efforts to save the mammals from trafficking.Xinhua News (21 November 2018) [https://web.archive.org/web/20181123065637/http://www.xinhuanet.com/english/2018-11/21/c_137620372.htm Spotlight: Pangolin conservationists call for ban on illegal trade of mammal products]China Plus (18 February 2017) [https://web.archive.org/web/20170222062715/http://english.cri.cn/12394/2017/02/18/3124s952140.htm World Pangolin Day: Conservationists demand greater protection to stop extinction]Xinhua News (8 June 2018) [http://www.xinhuanet.com/english/2018-06/08/c_137240161.htm How China is combating wildlife trafficking in Africa] {{Webarchive|url=https://web.archive.org/web/20201130050244/http://www.xinhuanet.com/english/2018-06/08/c_137240161.htm |date=30 November 2020 }} Wildlife conservation group TRAFFIC has identified 159 smuggling routes used by pangolin traffickers and aims to shut these down.{{cite web |title=Pangolins – Species we work with at TRAFFIC |website=www.traffic.org |url=https://www.traffic.org/what-we-do/species/pangolins/ |access-date=10 January 2019}}

Many attempts have been made to breed pangolins in captivity, but due to their reliance on wide-ranging habitats and very particular diets, these attempts are often unsuccessful.{{cite journal |last1=Aitken-Palmer |first1=Copper |last2=deMaar |first2=Thomas W. |last3=Johnson |first3=James G. |last4=Langan |first4=Jennifer |last5=Bergmann |first5=Jonathan |last6=Chinnadurai |first6=Sathya |last7=Guerra |first7=Hector |last8=Carboni |first8=Deborah A. |last9=Adkesson |first9=Michael J. |date=September 2019 |title=Complications Associated with Pregnancy and Parturition in African White-bellied Pangolins (Phataginus Tricuspis) |journal=Journal of Zoo and Wildlife Medicine |doi=10.1638/2019-0019 |volume=50 |issue=3 |pages=678–687 |pmid=33517639 |s2cid=202727948}} Pangolins have significantly decreased immune responses due to a genetic dysfunction, making them extremely fragile.{{cite journal |last1=Choo |first1=S.

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 the wild.
