Description

Víbora de cascabel encontrada en el Potrero de Los Venados, perteneciente a la Comunidad San José de Gracia. Cuando la vimos, estaba trepada en una palma (Yucca sp.) junto a un bordo de abrevadero; al acercarnos más resultó que no era una sino dos cascabeles las que estaban ahí.

Hábitat: Ecotono entre izotal y bosque de encino.

La foto del paisaje es del herpetólogo Alejandro Carbajal Saucedo.
