11. Round Island Keel-scaled Boa
The Round Island Keel-scaled Boa, scientifically known as Casarea dussumieri, is a unique and endangered snake species found exclusively on Round Island, located off the coast of Mauritius in the Indian Ocean. This boa is notable for its highly specialized adaptations and restricted distribution, making it a critically important species for conservation efforts.
The Round Island Keel-scaled Boa has a slender body that can reach lengths of up to 1.5 meters, with distinct keeled scales that give it a rough texture. Its coloration varies from light brown to reddish-brown, allowing it to blend seamlessly with the rocky terrain and dry vegetation of its island habitat. These boas are known for their docile nature and gentle disposition, often making them a popular choice among snake enthusiasts.
What sets the Round Island Keel-scaled Boa apart from other boas is its remarkable adaptation for a life in the trees. It possesses prehensile (grasping) tails and longer, more slender bodies than its mainland relatives, enabling it to maneuver adeptly through the branches. This unique adaptation has likely evolved due to the absence of mammalian predators on Round Island and the abundance of arboreal habitat.
