A supremely adaptable
species, the Asian House Rat is to be found in many man-made habitats
including agricultural and wholly urban areas. It is omnivorous, feeding on
all manner of farmyard waste and food scraps. It is a fast runner, can climb
well and can jump up to 50 cm.
The fur on the dorsal side
is olive-brown, and the ventral side generally lighter. The tail is very
dark grey and nearly naked. The ears are large and the eyes jet black. Juveniles have a
relatively larger head and smaller body.
species is closely related to the European House Rat Rattus rattus, but
recent studies suggest it is a separate species. It probably occurs
throughout Southeast Asia.
