Oryzomys gorgasi
Oryzomys gorgasi.
Oryzomys gorgasi, also known as Gorgas's rice rat, is a rodent in the genus Oryzomys of the family Cricetidae. First collected as a living animal in 1967, it is known from only a few localities, including a freshwater swamp in the lowlands of northwestern Colombia and a mangrove islet in northwestern Venezuela. An extinct form from the island of Curaçao off Venezuela has been described as a separate species, O. curasoae, but does not differ morphologically from mainland populations. It is a medium-sized, brownish species with large, semiaquatically specialized feet. It differs from other Oryzomys species in several features of its skull. Its diet includes crustaceans, insects, and plant material, and parasitic nematodes infect it. The species is listed as "Endangered" by the IUCN due to destruction of its habitat and competition with the introduced black rat. (This article is part of a featured topic: Oryzomys.)
