Physical characteristics

Desmarest's Hutia ranges in size from 20 cm to 60 cm (8 in to 24 in). It weighs between 1 kg and 9 kg (2.2 lb to 20 lb), averaging 7 kg (15.5 lb). It has thick, coarse fur

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

Interaction with humans

Hutias were traditionally hunted for food in Cuba as their flesh was agreeable and their size meant they provided a substantial meal. In a few places they were raised in barns and used as a minor stock animal. The Wild Animals Protection Act of 1968 made it illegal to hunt or kill hutias without a permit from the Ministry of Agriculture and Fisheries

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.
