Anolis desechensis is a member of the A. cristatellus species complex from Puerto Rico. Found only on the tiny island of Desecheo, very little is known about its natural history. In fact, some might question whether it should be a distinct species, but in the absence of any data, it’s hard to say.
This lovely photo comes from the Facebook page of Island Conservation, a wonderful organization devoted–as its name implies–to the conservation of island biota. I just heard a talk yesterday crediting them for eradicating rats from an island in the Galapagos, paving the way for preservation of a unique giant tortoise race. But that’s another story.
