Pantherophis guttatus meahllmorum (Thornscrub Rat Snake)
Central Texas Coast, Spring 2014
Found under a piece of tin nestled amongst a thick smattering of cord grass near the edge of a salt flat.
This individual was the largest I have seen, between three and four feet in length. It appeared to be nearing the end of a shed cycle.
Well detailed when viewed large.
