Hutia
Hutias (known in Spanish as jutía) are moderately large cavy-like rodents of the subfamily Capromyinae that inhabit the Caribbean Islands. Twenty species of hutia have been identified but at least a third are extinct. Only Desmarest's hutia and the prehensile-tailed hutia remain common and widespread; all other extant species are considered threatened by the IUCN. The extinct giant hutias of the family Heptaxodontidae also inhabited the Caribbean, but are not thought to be closely related, with the giant hutias belonging in the superfamily Chinchilloidea. Description. Most species have a head-and-body length that ranges from  and weigh less than , but Desmarest's hutia has a head-and-body length of and weighs . They resemble the coypu 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. 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 an abundant food source and the  lack of natural predators. 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. Phylogeny. Molecular studies of phylogeny indicate that hutias nest within the Neotropical spiny rats (Echimyidae). Indeed, the hutia subfamily, Capromyinae, is the sister group to Owl's spiny rat "Carterodon". In turn, this clade shares phylogenetic affinities with a subfamily of spiny rats, the Euryzygomatomyinae. Within Capromyidae, the deepest split  involves "Plagiodontia" with respect to other genera, followed by the divergence of "Geocapromys". The latter genus is the sister group to a clade in which "Capromys" branches off before the "Mesocapromys" and "Mysateles" split. Hutias colonized the islands of the Caribbean as far as the Bahamas by island hopping from South America, reaching the Greater Antilles by the early Oligocene. This was facilitated by the direction of prevailing currents. Systematics. The systematics of the 10 extant and 11 extinct recognized species of Capromyidae is as follows. Taxa known to be extinct are marked with a dagger (†).
