The black-tailed hutia is a rare rodent with dark fur and a black tail. This animal lives only in Cuba in dense forests and mangrove thickets.
The black-tailed hutia is distinguished from other hutia species by its black tail. It is important for Cuba's nature as a plant seed disperser and part of the food chain.
