Uromys is a genus of rodents found in Melanesia and Australia. They are known as the giant naked-tailed rats. There are eleven species in the genus, with the most recent described in 2017.
The Old World rats and mice, part of the subfamily Murinae in the family Muridae, comprise at least 519 species. Members of this subfamily are called murines. In terms of species richness, this subfamily is larger than all mammal families except the Cricetidae and Muridae, and is larger than all mammal orders except the bats and the remainder of the rodents.
The bush rat or Australian bush rat is a small Australian nocturnal animal. It is an omnivore and one of the most common indigenous species of rat on the continent, found in many heathland areas of Victoria and New South Wales.
Megalomys luciae, also known as the Saint Lucia pilorie or Saint Lucia giant rice-rat, as well as several variant spellings, is an extinct rodent that lived on the island of Saint Lucia in the eastern Caribbean. It was the size of a small cat, and it had a darker belly than Megalomys desmarestii, a closely related species from Martinique, and slender claws. Some other physical features that this rodent species have are brown/ochre dorsal coloration and white soft fur patches. They have webbed hind feet, smooth heels with interdigital pads, and slender claws. Their tail is longer than the length of their whole body from head to toe, the tail contains sparse hairs and is mainly covered with epidermal scales. Their skulls are very delicate with an amphora shape. The last known specimen died in the London Zoo in 1852, after three years of captivity. It probably became extinct in the latter half of the 19th century, with the last record dating from 1881. There is a stuffed specimen in the collection of the Natural History Museum in London.
Vangunu is an island, part of the New Georgia Islands in the Solomon Islands. It is located between New Georgia and Nggatokae Island. To the north and east of the island is Marovo Lagoon. The island has an area of 509 square kilometres (197 sq mi).
The giant white-tailed rat is an Australian rodent native to tropical rainforest of north Queensland, with subspecies occurring in New Guinea and the Aru Islands. It is one of the largest rodents in Australia, reaching up to 1 kg in weight. It is grey-brown above, cream to white below, and has a long, naked tail of which the distal section is white.
Poncelet's giant rat or Poncelet's naked-tailed rat is a species of rodent in the family Muridae. It is found in Papua New Guinea and Solomon Islands.
Solomys is a genus of rodent in the family Muridae. These large rats, which are all seriously threatened, are native to the Solomon Islands.
The Florida naked-tailed rat is a poorly known and possible extinct species of rodent in the family Muridae. It was confined to the Nggela Islands in the Solomon Islands. The originally mentioned type locality Ugi Island is an erratum.
The giant naked-tailed rat is a species of rodent in the family Muridae. It is found in West Papua, Indonesia and Papua New Guinea. It lives in tropical forests, wetlands, and in degraded forests.
The masked white-tailed rat is a species of rodent in the family Muridae. It is found only in Australia, in north-east Queensland.
The king rat is a large species of rodent in the family Muridae. It is endemic to the island of Guadalcanal in the Solomon Islands. Like the two other species of rodent in Guadalcanal, it is placed in the genus Uromys. It lives in trees and is larger than Uromys porculus but smaller than Uromys imperator.
The Guadalcanal monkey-faced bat or Guadalcanal flying monkey is a megabat endemic to Solomon Islands. It is listed as an endangered species. In 2013, Bat Conservation International listed this species as one of the 35 species of its worldwide priority list of conservation.
The Great Key Island giant rat, or Great Key Island uromys is a species of rodent in the family Muridae. It is known only from Great Key Island, Indonesia.
The Vangunu giant rat, locally known as the vika, is a giant arboreal species of rodent in the family Muridae. The rat was discovered in the island of Vangunu in the Solomon Islands in 2015, after years of searching based on local stories, and described in 2017. It was identified as a new species on the basis of its skull, skeleton and a detailed DNA analysis. The single individual initially collected from a felled tree measured 46 cm long, weighed between 0.5 and 1.0 kg and had orange-brown fur. Its diet is believed to include thick-shelled nuts like ngali nuts and coconuts, and probably fruits. The species is likely to be designated critically endangered, due to the small amount of forest habitat remaining on the island and ongoing logging.
