About the Ambergris Cay Dwarf Boa
Common names: Ambergris Cay dwarf boa, Caicos Islands dwarf boa, Caicos trope.
Tropidophis greenwayi is a nonvenomous dwarf boa species endemic to the Caicos Islands. Two subspecies are currently recognized, including the nominate subspecies described here.
Etymology
The specific name, greenwayi, is in honor of American ornithologist James Cowan Greenway.
Description
Adults of T. greenwayi reach maturity at a total length (including tail) of 225 mm (8.9 in) in males and 250–265 mm (9.8–10.4 in) in females. The maximum total length is 38 cm (15 in).
Geographic range
T. greenwayi is found in the West Indies in the Caicos Islands, particularly on the islands of Ambergris Cay, Long Cay, Middle Caicos, Middleton Cay, North Caicos, South Caicos, and probably also on Providenciales. The type locality given is "Ambergris Cay, Caicos Islands, Bahamas".
Habitat
T. greenwayi occurs in the rocky limestone areas of the cays, in shrubland, forest, and rural gardens.
Conservation
Because of its restricted island distribution, T. greenway is susceptible to extirpation. Unless wildlife protection laws are enforced, the relatively secretive nature of this snake may be its only protection against extinction.
Diet
The diet of T. greenwayi consists mainly of anoles, geckos, and frogs.
