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.

Insistentemente durante los talleres con grupos focales la gran mayoria de los productores afirmaron que las serpientes Erythrolamprus mimus, Pliocercus euryzonus, Oxyrhopus petolarius, Lampropeltis triangulum y Micrurus nigrocinctus, conocidas localmente como corales, son venenosas, ademas hicieron enfasis en que estos colubridae pican o hincan con la cola, debido a un aguijon presente en esta parte de su cuerpo el cual puede causar la muerte en humanos.

Ontogenetic pattern change like that observed for some populations of Oxyrhopus petolarius involving progressive melanism beginning posteriorly might account for the presence of anterior rings in some specimens of L.
