The Black Rat is a common long-tailed rodent of the genus Rattus in the subfamily Murinae. The species originated in tropical Asia and spread through the Near East in Roman times before reaching Europe by the 6th century and spreading with Europeans across the world. Today it is again largely confined to warmer areas, having been supplanted by the Brown Rat in cooler regions. Despite its name, it exhibits several colour forms. It is usually black to light brown in colour with a lighter underside. A typical rat will be 15 20 cm long with a further 20 cm of tail. It is nocturnal and omnivorous, with a preference for grains and fruit. Compared to the Brown Rat, it is a poor swimmer, but more agile and a better climber, tending even to flee upwards. In a suitable environment it will breed throughout the year, with a female producing three to six litters of up to ten young. Females may regulate their production of offspring during times when food is scarce, throwing as few as only onelitter a year. R. rattus lives for about 2 3 years. Social groups of up to sixty can be formed.
