agouti

agouti (əgōō´tē), name applied to rabbit-sized rodents of the genus Dasyprocta, found in Central and South America and in the West Indies. They have slender limbs with five front and three hind toes, rudimentary tails, and coarse rough hair that varies from reddish to dark brown depending upon the species. Agoutis are forest dwellers; they eat fruits, leaves, roots, nuts, and sugarcane. They are good swimmers and fast runners. Agouti is occasionally used instead of Cuniculus as the generic name of the related paca, or spotted cavy. Agoutis are classified in the phylum Chordata, subphylum Vertebrata, class Mammalia, order Rodentia, family Dasyproctidae.

agouti

agouti In mammals, the hair colour produced when each hair consists of alternate eumelanic and phaeomelanic bands. According to the theory of metachromism, agouti is the evolutionarily primitive mammalian hair colour. The pattern is named after the agouti (Dasyprocta aguti), a South American rodent with hair banded in this way.

Agouti

Agouti

The twelve species of agoutis are the best-known members of the family Dasyproctidae (genus Dasyprocta ) of the order Rodentia. Agoutis are found from southern Mexico through Central America to southern Brazil, including the Lesser Antilles. They are long-legged, slender-bodied, rabbit-like mammals with short ears and a short tail. The body length of agoutis measures 16-24 inches (41.5-62 cm), and adults weigh 3-9 pounds (1.3-4 kg). The fur is quite coarse and glossy, and is longest and thickest on the back. The fur ranges from pale orange through shades of brown to black on the backside, with a whitish, yellowish, or buff-colored underside. The back may be striped.

The forelimbs each have four digits, while the hind limbs have three hoof-like claws. The cheek teeth have high crowns and short roots, a condition known as hypsodont.

Agoutis live in cool, damp, lowland forests, grassy stream banks, thick bush, high dry hillsides, savannas, and in cultivated areas. These animals are active during the day, feeding on fruit, vegetables, and various succulent plants, as well as corn, plantain, and cassava root. Agoutis eat sitting erect, holding the food with their forelimbs. They collect and store seeds and fruits, and since they often forget the locations of these stores, they are important dispersers of rainforest seeds.

Female agoutis have eight mammary glands, and usually two, but up to four, young are born at one time. Mating may occur twice a year, and there is a three-month gestation period. The young are born in a burrow that is dug out among limestone boulders, along river banks, or under the roots of trees. The nest is lined with leaves, roots, and hair. The life span of agoutis in captivity is 13-20 years.

Jaguars and other large carnivores prey on agoutis, and they also are heavily hunted by humans. When threatened they will freeze and then run away quickly if the threat continues. The World Conservation Union (IUCN) lists two species of Dasyprocta as endangered and one as vulnerable.

Other members of the family Dasyproctidae, include the members of the genus Myoprocta, known as iacushi or iacuchi, agouti, icutia de rabo, icutiaia, or icotiara. They are much smaller than agoutis and have a longer tail. Agoutis (genus Dasyprocta ), are also known in their geographical range as iagutis, inequis, icutias, icotias, ikonkoni, icotuzas, and ipicure.

Members of the genus Plagiodontia inhabit the Dominican Republic (P. aedium ) and Haiti (P. hylaeum ), and the latter is sometimes incorrectly referred to as an agouti or izagouti. The genus Plagiodontia are rodents of the family Capromyidae and correctly called Hispaniolan hutias or jutias.
