Black rat

The black rat (Rattus rattus), also known as the roof rat, ship rat, or house rat, is a common long-tailed rodent of the stereotypical rat genus Rattus, in the subfamily Murinae. It is a generalist omnivore that can live on a wide variety of foods. It associates extensively with humans, and most populations are synanthropic. It likely originated in the Indian subcontinent, but is now found worldwide. The black rat is black to light brown in colour with a lighter underside. It is a prominent pest to farmers because it feeds on a wide range of agricultural crops. It is sometimes kept as a pet, though most domestic rats are a subspecies of the brown rat. In parts of India, it is considered sacred and respected, notably at the Karni Mata Temple in Deshnoke.
