Oxyrhopus

Oxyrhopus

 

a genus of poisonous snakes of the Colubridae family.

The length of Oxyrhopus ranges to 1.2 m. The back teeth of the upper jaw are enlarged and have a groove on the front edge for transmitting poison fatal to small animals. The poison is not dangerous to man. There are 12 species, found in southern Mexico and Central and South America (as far south as Argentina). They are active primarily at dusk. Oxyrhopus live in forests, brush thickets, and rock piles. They feed on amphibians, lizards, small mammals, and birds. Some species, particularly Oxyrhopus trigeminus, look similar to the highly poisonous coral snakes because of the bright coloration, with red and black lateral stripes.
