Proechimys
Genus of mammals belonging to the spiny rat family of rodents / From Wikipedia, the free encyclopedia
Proechimys is a genus of South American spiny rats of the family Echimyidae.[1] All species of the genus are terrestrial. In the lowland Neotropical forests, Proechimys rodents are often the most abundant non-volant mammals.[2] They are recognizable by reason of their elongated heads and long rostra, large and erect ears, narrow and long hind feet, and tails always shorter than head-and-body lengths. The dorsal pelage comprises a mixture of expanded, varyingly stiffened spines (or aristiforms) — hence the vernacular name of spiny rats — and soft hairs (or setiforms).[2]
