Pangolin
Pangolins are the only mammal known to have scales. Parts of Central and West Africa, India, and Southeast Asia are home to these animals. Pangolins roll up into a defensive ball when threatened by predators, protected by their armor-like keratin scales. Unfortunately, insectivores are some of the world’s most illegally traded mammals. In some parts of Asia, their scales are thought to have medicinal properties, and despite an international trade ban, wild pangolin populations have plummeted as a result of poaching.
Tasmanian Devil
The Tasmanian devil is the world’s biggest carnivorous marsupial. Despite their resemblance to a small dog, devils are more closely related to wallabies than canines and carry their young in pouches. However, Tasmanian devil populations have plummeted in recent years due to a naturally occurring cancer known as Devil Facial Tumor Disease. The Tasmanian Devil Unzoo, a wildlife sanctuary dedicated to rehabilitating devils and researching the disease, claims, however, that the animals are adapting to fight back.
