The Vangunu giant rat (Uromys vika), locally known as the vika, is a giant arboreal species of rodent in the family Muridae.[1][2] The rat was discovered in the island of Vangunu in the Solomon Islands in 2015,[3] after years of searching based on local stories, and described in 2017.[4] It was identified as a new species on the basis of its skull, skeleton and a detailed DNA analysis.[1] The single individual initially collected from a felled tree (Dillenia salomonensis) measured 46 cm long, weighed between 0.5 and 1.0 kg and had orange-brown fur.[1] Its diet is believed to include thick-shelled nuts like ngali nuts and coconuts,[3] and probably fruits.[1] The species is likely to be designated critically endangered, due to the small amount of forest habitat (about 80 km2) remaining on the island and ongoing logging.[1][2]
