"Pangolins (pronounced /ˈpæŋgəlɪn/) or scaly anteaters are mammals in 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 scales on their skin and 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."
