Although it is quietly hued, the little Hispaniolan cat-eyed snake, Hypsirhynchus ferox, is both attractive and interesting. Inhabiting a wide range of habitats from xeric to mesic, this terrestrial snake seems to prefer areas where low escarpments and boulders are prominent, on the Caribbean island of Hispaniola (Haiti and the Dominican Republic).
Preferentially a lizard eater, juvenile snakes eat geckos, anoles and the young of larger lizards. Adults feed upon larger whiptails and curly-tailed lizards. This snake occasionally attains a length of 30 inches (rarely an inch or two longer, often a few inches shorter). It is slender and can move quickly.
