Hutias are moderately large cavy-like rodents of the family Capromyidae that inhabit the Caribbean Islands. Most species have a head-and-body length that ranges from 21 to 46 cm (8.3 to 18.1 in) and weigh less than 2 kg (4.4 lb), but Desmarest's hutia has a head-and-body length of 31 to 60 cm (12 to 24 in) and weigh 2.8–8.5 kg (6.2–18.7 lb). Twenty species of hutia have been identified, and at least a third are extinct. (Their larger relatives the giant hutias, of the family Heptaxodontidae, are entirely extinct.) They resemble the nutria in some respects. Tails are present, varying from vestiges to prehensile. They have stout bodies and large heads. Most species are herbivorous, though some consume small animals. Instead of burrowing underground, they nest in trees or rock crevices. Only Desmarest's hutia and the prehensile-tailed hutia remain common and widespread; all other extant species are considered threatened by the IUCN.
They are hunted for food in Cuba, where they are often cooked in a large pot with wild nuts and honey. At the Guantanamo Bay Naval Base however, there is an over population due to the lack of natural predators and an abundant food source. Desmarest's hutias are referred to by those stationed at the Guantanamo Bay Naval Base as banana rats. Banana rats are not named for their dietary preference, but because their feces look like small versions of the fruit. They are known to come out at night. According to Blair Hedges of Penn State University the Guantanamo Bay Naval Base may be the Hutia's last home.

These small mammals resemble a groundhog or a marmot with a yellow-colored fur. Related to guinea pigs, the hutias' only remaining home may well be at Guantanamo. Commonly called "banana rats" by residents of the base, hutias live in abundance at Guantanamo, but their existence in other parts of the world has eluded Dr. Hedges's awareness."
