An arboreal species endemic to Cuba. It is an insular animal found in holes, under rock piles and on cultivated land.
It is a constrictor hunter and, when it catches its prey, it wraps its body around it. With each exhalation from the prey, it squeezes harder until it suffocates it, then it swallows the prey head-first by unhinging its jaws.
It is ovoviviparous, meaning the eggs develop inside the mother's body, covered by a membrane rather than a shell. It then gives birth to 6 or 7 live young that are independent from birth.
It is hunted and killed by humans because they believe it eats their chickens.
