lives only in Cuba and on several, small nearby islands, however they occupy many different habitats throughout Cuba. (Phillips et al. 1991)
are widespread throughout all of Cuba. They are found in all types of habitats such as montane cloud forests, arid coastal semi-deserts, semi-deciduous forests, low, marshy areas and even in the mountains of eastern Cuba. Cuban hutias can possibly be divided into two groups: those that live in northern Cuba and those that live in southern Cuba. Those that live in the north tend to live in marshy areas where an abundance of red mangroves grow. This group generally lives in the branches and roots of the mangroves that grow there. However, those in the south tend to be more terrestrial.
(Poiez et al. 1992, Phillips et al. 1991, Alvarez & Gonzalez 1991)
Cuban hutia can range anywhere from 20 to 60 cm in length (varying from individual to individual) and between 1 and 9 kg in weight.are the largest species of hutias. They are, on average, 60.96 cm long and 7 kg in weight. have short, stocky legs which cause them to move in a "waddling" motion. However, in times when they need to move quickly (like while being chased) they are capable of hopping. have thick, coarse fur with the dorsal area generally a darker shade than the ventral side. The shades of fur can vary greatly from black and brown to yellowish shades or even reddish shades. The tail is completely covered with hair and is a solid shade of color. have large claws on their feet, which aid in climbing. Cuban hutias and their close relatives (C. garridoi and C. arboricolus) have a complex stomach divided into three compartments, this is the most complex stomach morphology found in rodents. Females have two lateral thoracic pairs of mammae.
(Phillips et al. 1991, Nowak 1999, Alados et al. 1990)
The life expectancy of Cuban hutia in captivity ranges from 8 to 11 years. Their breeding season is year round and they have a gestation period of around 120-126 days. Most Cuban hutias have 1-3 young per birth that weigh on average 8 oz at birth. The young are born precocial, able to move around, well-furred, and with their eyes open. Despite the fact that they are born so well developed, they are not completely weaned for approximately 5 months. In addition, they do not reach sexual maturity until they are about 10 months old.
(Phillips et al. 1991)
are generally shy and live mainly in groups of about two.
Despite their secretive behavior, they are socia within their species. There are a few different types of social behavior that they engage in regularly. One of these types is scent marking. This is a common form of communication among hutias which provides a way of keeping track of their own kind. Scent marking is done by both males and females and is done through the use of urine. Another type of social behavior commonly found in Cuban hutias is a sort of grooming/wrestling. In a very non-aggressive sort of way, they often engage in a behavior that involves intermittent grooming sessions with tumbling around on each other.
(Phillips et al. 1991)
are omnivores that generally feed on things such as leaves, fruits, and bark from trees. However, they have been known to also feed on small vertebrates, including small lizards.
They have easy access to the vegetation high up in the trees due to their great climbing ability, but the majority of the time they feed on vegetation closer to ground level.
Humans enjoy the meat frombecause it tastes great and since the animal is of substantial size each hutia provides a significant amount of meat. (Phillips et al. 1991)
Some areas actually have such an abundance ofthat they harm the vegetation of the area. (Alvarez & Gonzalez 1991)
The Wild Animals Protection Act of 1968 protects hutias from being captured or killed unless a permit is obtained from the Ministry of Agriculture and Fisheries.are not as much of a conservation concern because there still are some areas that have a high density of this species. The only area where the species population has diminished tremendously is in the mountains of eastern Cuba. However, other species of hutias are endangered or have already gone extinct.
Although they are not of immediate concern, a transplantation has taken place in an effort to ensure the survival of Cuban hutias. This transplantation removed some C.pilorides from East Plan Cay and transplanted them to the Exuma Cays Land and Sea Park.
There are also some protected areas where the density of C.pilorides has reached 50-100 individuals per hectare. However, there are still some places where their population has diminished greatly such as in the mountains of eastern Cuba. (Alvarez & Gonzalez 1991)
