Description

A medium-sized, brown garter snake with yellow-green stripes from the vicinity of Tepic, in the Mexican state of Nayarit, where it has been observed catching small fish from streams. Thamnophis rossmani was previously considered a disjunct population of Mexican Garter Snake, Thamnophis eques. Conant (2000) elevated it to full species status based on morphological differences. The largest specimen collected was a female 74.5 cm in length, but had a severely stubbed tail and would have been even longer if intact; that specimen’s snout-vent length of 64.8 cm is listed instead.

Conservation

The habitat of Rossman’s Garter Snake is quite limited, and, according to Conant, has suffered significant alteration since the 1960s; this species may be at significant risk if not already extinct.
