“The four Chilian species of Armadillo (Dasypus) are nearly 
similar in habits. The Peludo (D. villosus) is nocturnal; while the 
others wander by day over the open plains, feeding on beetles, larvee, 
roots, and even small snakes. The Pichy (D. minutus) prefers a 
very dry soil and the sandy dunes near the coast, where for many 
months it can never taste water. In soft soil the animal burrows so 
quickly that its hinder quarters would almost disappear before one 
could alight from one’s horse.””—Darwin’s Journ. p. 96.
