Mesocapromys nanus (dwarf hutia)

Wikipedia Abstract

The dwarf hutia (Mesocapromys nanus) is known only from Cuba. It was last seen in 1937. The hutias are heavily built guinea pig-like rodents with broad rounded heads. They have relatively small eyes and short rounded ears. The average tail and body length of this hutia is unknown. Some hutias have prehensile tails, meaning they are able to use them for gripping and climbing. Unlike the larger litter sizes of many other rodents, the dwarf hutia gave birth to only a single offspring.

EDGE Analysis

One of the few modern mammals to be first described from fossil remains, this species was thought to be extinct until living animals were discovered. Once widely distributed across mainland Cuba and the neighbouring Isle of Pines, by the early twentieth century the dwarf hutia was restricted to the largely inaccessible Zapata Swamp. The last individuals known to science were captured in 1937, but local reports and the discovery of tiny droppings suggest that the species may have persisted beyond this date. The species is now feared extinct, having suffered declines following the introduction of black rats and mongooses, and conversion of much of its forest habitat to sugarcane plantations.
