A Pangolin and also scaly anteater or Trenggiling, is a mammal of the order Pholidota. There is only one extant family (Manidae) and one genus (Manis) of pangolins, comprising eight species. There are also a number of extinct taxa. Pangolins have large keratin scales covering their skin and are the only mammals with this adaptation.[2] They are found in tropical regions of Africa and Asia. The name "pangolin" derives from the Malay word pengguling ("something that rolls up"). Pangolins are nocturnal animals, using their well-developed sense of smell to find insects. The long-tailed pangolin is also active by day. Pangolins spend most of the daytime sleeping, curled up into a ball.[3]
Pangolins were classified with various other orders, for example Xenarthra, which includes the ordinary anteaters, sloths, and the similar-looking armadillos. But newer genetic evidence[4] indicates that their closest living relatives are the Carnivora, with which they form the clade Ferae.[5] Some paleontologists have classified the pangolins in the order Cimolesta, together with several extinct groups.
