Dark-tailed tree rat

The dark-tailed tree rat, also called the Sundaic arboreal niviventer (Niviventer cremoriventer), is a species of rodent in the family Muridae. The Wikipedia article that serves as this entry's source says it is found on the Malay Peninsula, in Thailand and Malaysia, on some offshore islands such as the Mergui Archipelago of Myanmar, and in parts of the Malay Archipelago, including Singapore, the Anambas Islands, Sumatra, Nias, Belitung, Bangka, Java, Bali and Borneo. It might be a species complex. It is common, lives both in trees and on the ground in primary and secondary forest but not outside forests, and is threatened by the loss of those habitats, especially in lowland areas.
