Roof Rat

The black rat (Rattus rattus), also known as the ship rat, roof rat, house rat, is a common long-tailed rodent of the genus Rattus (rats) in the subfamily Murinae.[1] The species originated in tropical Asia and spread through the Near East in Roman times before reaching Europe by the 1st century and spreading with Europeans across the world.[citation needed]

Black rats are generalist omnivores. They are serious pests to farmers as they eat a wide range of agricultural crops.

Description

A typical adult black rat is 12.75 to 18.25 cm (5.0–7.2 in) long, not including a 15 to 22 cm (5.9–8.7 in) tail, and weighs 75 to 230 Gramms, depending on its subspecies.[3][4][5][6] Despite its name, the black rat exhibits several colour forms. It is usually black to light brown in colour with a lighter underside. In England during the 1920s, several variations were bred and shown alongside domesticated brown rats. This included an unusual green tinted variety.[7] The black rat also has a scraggly coat of black fur, and is slightly smaller than the brown (Norway) rat.
