Dorsal (back) view of the four species of rodent present in New Zealand. From left to right – Norway rat, ship rat, kiore and house mouse. Note the proportional difference in tail length from that of ship rats: Norway rat tails are shorter than their body, whereas ship rat tails are the same length as the body. The photograph was taken using study skins housed at Auckland Museum.
