The Polynesian Rat is similar in appearance to the Black Rat, but smaller, averaging around 12cm in body-length with a 13cm tail. Where it exists on smaller islands it tends to be smaller still.

An adept climber, the Polynesian Rat has been known to nest in trees. A nocturnal animal is one that sleeps during the day and is active at night - the opposite of the human (diurnal) schedule. ...
