Senticolis triaspis, also known as green rat snake, is a long (160 cm), green or olive green snake with the light yellow ventral side. They usually inhabit evergreen forests and grassland. They are well distributed in the Baboquivari, Pajarito, Atascosa, Santa Rita, Empire, Patagonia, Chiricahua, Swisshelm, Pedregosa, and Peloncillo mountains of southeastern Arizona. Senticolis triaspis consume small animals such as lizards, killing them by deadly constriction. They are primarily diurnal. During reproduction, they are able to lay up to 9 eggs in a clutch.[2]
