Boa constrictor
Due to the insular and oceanic nature, terrestrial fauna is limited and presents a high degree of endemism. Only a single species of frog (Leptodactylus insularis) and a single species of terrestrial turtle (Geochelone carbonaria) have been found. Two species of snakes (Boa constrictor imperator and Leptotyphlops magnamaculata), 6 of saurians, 10 of birds, 4 of sea turtles and a few of mammals have also been reported.
