 They move with great swiftness either on the ground or in 

 the bushes. When secured they sometimes fight vigorously, 

 coiling themselves about the limbs of the bushes, biting, and 

 resisting capture to the utmost (Taylor). The stomach of 

 one specimen contained an adult Cnemido'phorus tigris 

 (Ruthven & Gaige).
