Temminck's pangolin. A pangolin's scales, like fingernails, are made up of keratin, thus totally devoid of any medicinal or nutritional value. Yet they are under threat of poachers selling them to ignorant buyers believing in their medicinal use. The world's most trafficked animal is very shy and on every wildlife photographer's "want" list. REST is a facility for pangolin where rescued animals are cared for and released into the wild. The recovering animals are walked in the wild every day.
