Pangolin | Species | WWF » What’s scaly from tip to tail and can curl into a ball? Pangolins! These solitary, primarily nocturnal animals, are easily recognized by their full armor of scales. A startled pangolin will cover its head with its front legs, exposing its scales to any potential predator. If touched or grabbed it will roll up completely into a ball, while the sharp scales on the tail can be used to lash out. Also called scaly anteaters because of their preferred diet, pangolins are the most trafficked mammal in the world—with demand primarily in Asia and in growing amounts in Africa—for their meat and scales. There is also demand in the United States for pangolin products, particularly for their leather to be used in boots, bags, and belts. Eight species of pangolins are found on two continents. They range from Vulnerable to Critically Endangered. Four species live in Africa: Black-bellied pangolin (Phataginus tetradactyla), White-bellied pangolin (Phataginus tricuspis), Giant Ground pangolin (Smutsia gigantea) and Worldwildlife.org
