Cuban hutia

Appearance

Desmarest's hutia has a head-and-body length of 31–60 cm , a tail that is 14–29 cm long, and weigh 2.8–8.5 kg . It has thick, coarse fur which extends to the tip of the tail. The colour of the body fur varies from black to brown, with a light sand colour and red also seen. The body is stocky and the legs short. It moves with a slow, waddling gait, but can perform a quick hop when pursued. The feet have five toes with large claws which assist the animal in climbing. The stomach is divided into three compartments by constrictions in the gut and is among the most complex of any rodent.

Its karyotype has 2n = 40 and FN = 64.

Naming

First described by Pallas in 1788 as ''Mys pilorides'', it was later noted that Desmarest's hutia did not belong in that genus, and it was placed in the genus ''Capromys'' by Tate in 1935. Five subspecies are recorded: ''ciprianoi'', ''doceleguas'', ''gundlachianus'', ''pilorides'', and ''relictus''. Studies have so far shown no genetic differences between the two subspecies ''ciprianoi'' and ''relictus'' found on Isla de la Juventud, but a 5% sequence deviation by ''gundlachianus'' found on Cayo Fragaso. The common name, Desmarest's hutia, is for Anselme Gaëtan Desmarest who described the species in 1822 with the synonym ''fourniere''.

Distribution

Desmarest's hutia is found in a wide range of habitats. In northern Cuba, populations tend to be centred on areas where there are abundant mangroves, while southern populations tend to favour a more terrestrial habitat.


Desmarest's hutia is found only in Cuba, but is widespread throughout its range. They are found on the main island, Isla de la Juventud, the Sabana archipelago, the Doce Laqunas archipelago and many of the other islands and cays of the Cuban archipelago. They are abundant in Guantánamo Province, particularly around the Guantanamo Bay Naval Base. In the mountainous areas of eastern Cuba, numbers of Desmarest's hutia are decreasing.

Behavior

Desmarest's hutias normally live in pairs, but can be found individually or in small groups. They are diurnal and do not burrow, so during the night they rest in hollows in rocks or trees. They are omnivorous but eat mostly bark, leaves and fruit. Occasionally they will take small vertebrates such as lizards. Both males and females scent mark their territory with urine. They breed throughout the year with a gestation period of between 110 and 140 days , although peak breeding season is in June/July. They normally produce between one and three young, weighing an average of 230 g . The young are precocial, with fur, fully open eyes and the ability to walk. They are weaned at around five months and reach sexual maturity at around ten months. In captivity they live for eight to eleven years.
