False Terciopelo - Xenodon rabdocephalus


















This afternoon, whilst clearing up the workshop, Reinaldo found this False Terciopelo (Xenodon rabdocephalus) under black plastic bag and clearly having had a good meal recently. It would be easy to be fooled by this non-venomous mimic, and when it inflates its cheeks it looks distinctly viperish. But in the False Terciopelo, the head scales are variable in size (both large and small). A true, deadly venomous, Terciopelo has consistently small scales on its head (all the same size). Infact that's how to distinguish between venemous and non-venomous snakes. But the rule is, don't get close enough to any snake to inspect the size of its head scales! Reinaldo nearly stepped on an adult Terciopelo (ca. 2 meters!) on a forest trail this morning, at around 9am. So they seem to be out and about now, with the onset of the rainy season.
