| Aristelliger cochranae Grant, 1931 |
The Cochran's croaking gecko (Aristelliger cochranae), also known as Navassa gecko, was first described in 1931 by Chapman Grant and named after notable herpetologist and artist Doris Mable Cochran. The species received its common name from the load croaking call of the males during the mating period.
[edit] Description
The Cochran's croaking gecko is endemic to Navassa Island, an island between Haiti and Jamaica. It is relatively common despite its small habitat of 5.2 km². It can reach a length of 63 mm in males and 53 mm in females. It has relatively short and massive legs. The color of its body varies from beige brown to chestnut red and the back exhibits light spots. A dark chestnut crossband traverses from the snout to the head, the nape, and the eyes. The largest part of the tail is dark grey to black. The hatchlings have clear white crossbands on the tail.
It is nocturnal and arboreal, which means that it lives and preys entirely on the branches or under the bark of ficus trees or fan palms (Thrinax morrisii). Its diet consists of insects.
It is also a close relative to Aristelliger praesignis, the Jamaican "croaking lizard," which often finds its way into Jamaican households, much to the dismay of many Jamaican humans. Many Jamaicans fear this gecko because of its speed and ability to stick to walls, but especially because of the croaking sound it makes while they are trying to sleep.
