Pangolins are scaly mammals found in tropical areas of Asia and Africa. They have large scales covering most of their body and eat ants and termites. Pangolins are endangered because their meat is considered a delicacy in some areas like China, and their scales are believed to have medicinal properties. Additionally, over 2.7 million pangolins are hunted annually for their meat and scales, which has increased demand and driven up market prices significantly.
