Beautiful black-bellied pangolin

The one extant family, the Manidae, has three genera: Manis, Phataginus, and Smutsia. Manis comprises the 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). A number of extinct pangolin species are also known. 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.
