Emperor Rat (Uromys imperator)

The Emperor Rat, described in 1888, was endemic to the island of Guadalcanal, Solomon Islands, the species is known from only three specimens that all were taken between 1886 and 1888.


The Emperor Rat was very large, reaching a total length of about 60 cm, including the tail. It is believed that this species inhabited the rainforests, probably being a ground-dweller and feeding on fruits and other plant material.

The species may have survived until the 1960s, since the native people at that time still knew of a large, ground-dwelling rat living in the forests. The main reason for its extinction very likely lies in the predation by introduced feral cats.
