Neotropical snake and Caribbean expert Bob Henderson writes: “In going over some prey data for a chapter on diet and foraging in species of Corallus and the dramatic dichotomy between West Indian and mainland Corallus, I came up with some numbers you might find interesting.
I recovered 970 vertebrate prey items from West Indian snakes. Of those, 559 (57.6%) were anoles. The next closest prey genus was Eleutherodactylus (129; 13.3%).
Among ground dwelling or largely ground-dwelling species (tropes, colubrids, dipsadids), anoles accounted for 54.1% of their prey. Among arboreal snakes (Corallus, Hispaniolan Epicrates, and Uromacer), anoles accounted for 64.1%.
I suspect there are very few West Indian macrostomatan snakes that do not include anoles in their diets at some time during their lives.”
