The Polynesian rat is a small rodent about 15 centimeters long. It lives on Pacific islands and spread there with ancient humans.
The Polynesian rat is smaller than black and gray rats and climbs plants better. It helps spread plant seeds, but on some islands it harms local birds by eating their eggs.
