The name,, pangolin,, is derived from Malay word,,pengguling,, which loosely translate to,, something that rolls up,, – and indeed, they do! When threatened, pangolins roll up into a ball, using their scales like armour. Pangolins do not have teeth and are unable to chew. Instead, they have long sticky tongues that they use to catch the insects they feed on. Their tongues can be up to 16 inches long!
