The Lesser Antillean Iguana (Iguana delicatissima) is a large arboreal lizard endemic to the Lesser Antilles. It is one of two species of lizard of the genus Iguana and is in severe decline due to habitat destruction, feral predators, hunting, and hybridization with its sister species the Green iguana. Successful captive breeding of this species has been limited to only two instances as most captive laid eggs tend to be infertile.
