Yucatán Rat Snake

Pseudelaphe phaescens
(Dowling, 1952)
Yucatán, Mexico. June 29, 2016.

The silver irises in this snake’s eyes are quite a striking feature. The bright colors of juveniles and young adults fade to silvers and blacks as they grow larger. The largest specimen I’ve seen was a female close to seven feet in length, observed crossing a road after midnight. Formerly a subspecies of Elaphe flavirufa, elevated to species by FLORES-VILLELA & CANSECO-MÁRQUEZ 2004.
