Senticolis triaspis triaspis
Yucatán, Mexico. June 25, 2016.
The first live snake encountered on my first trip to the Yucatán, found crossing a road just after dark. This snake needs a better common name, as it does not turn green on reaching adulthood, as does the northern subspecies S. t. intermedia. Adults in the peninsula are often brown or reddish brown in color.
