Pangolins, also known as scaly anteaters (family: Manidae, order: Pholidota), are unique among the mammals because of their overlapping scales (made of keratin) and have a geographic distribution that includes parts of Asia and Africa (Gaudin et al. 2009). Only eight pangolin species are present worldwide, four in Asia including China, and four in Africa. There is a growing interest in pangolin welfare, including the threats posed by poaching and the deforestation of their natural habitats (Hua et al. 2015). Most importantly, pangolins have become unfortunate icons for the international and domestic illegal trade in wildlife, and are the most trafficked mammal (Gaubert et al. 2018). Of the eight species, four are listed as vulnerable, two are endangered, and the remaining two are critically endangered on the International Union for Conservation of Nature Red List of Threatened Species (du Toit et al. 2017).
