Like all pangolins, the species is armored with large, brown to reddish-brown scales formed from keratin. Curiously, it also has

s and termite nests, both subterranean and mound-type. Because of its relatively large size, the giant pangolin is particularly well-suited to breaking open termite mounds by leaning on the mound and resting its weight on its tail, and then ripping into the mound with its front claws. The combination of weight and physical damage quickly leads to a partial collapse of the mound, exposing the termites. Only the adults are strong enough to do this; their young must follow behind their mothers until they grow large enough to do it for themselves. It eats the

They cannot walk on their legs, but can move on their bellies. During age 6–8 weeks, the young often spew a yellow secretion from their anal glands(that is often said to smell of decay and cabbage) to keep predators and other animals from taking advantage of their mothers.
