Cloud-dwelling spiny pocket mouse (Heteromys nubicolens)

The cloud-dwelling spiny pocket mouse belongs to the genus Heteromys in the family Heteromyidae, which includes all but one of the castorimorph species of South America. Like all of South America's other non-caviomorph rodents, they arrived in the continent relatively recently as part of the Great American Interchange. The cloud-dwelling spiny pocket mouse was first described in 2006 from a few locations in Costa Rica, and it has yet to be assessed by the IUCN.
