The Saban black iguana (Iguana iguana melanoderma), also known as the painted black iguana, is a subspecies of the green iguana found on the islands of Saba and Montserrat in the Caribbean. It is a melanistic morph of the green iguana, meaning that it has a dark black or brown coloration. The coloration is thought to be due to a genetic mutation that causes an overproduction of melanin. The Saban black iguana is larger than the green iguana, with adults reaching up to 6 feet in length. They have a black dewlap, high dorsal spikes, and no horns on the snout. The black facial patch between the eye and tympanum is also a distinguishing characteristic. The Saban black iguana is an arboreal lizard that lives in the rainforests of Saba and Montserrat. They are omnivorous, eating fruits, leaves, insects, and small animals. The lizards are preyed upon by hawks, snakes, and feral cats. The Saban black iguana is a protected species in both Saba and Montserrat. However, the population is declining due to habitat loss, predation, and the introduction of non-native species.
