Black Rat
The Black Rat (Rattus rattus), also known as the ship rat, roof rat, or house rat, is a common long-tailed rodent of the stereotypical rat genus Rattus, in the subfamily Murinae.
Pronunciation
- IPA: /blæk ræt/
Etymology
The term "Black Rat" originates from the rat's dark fur, which distinguishes it from the Brown Rat. The term "rat" is derived from the Old English "ræt," which is likely borrowed from the Old High German "rato."
Description
The Black Rat is slightly smaller than the Brown Rat and has a longer tail. It is usually black to light brown in color. A typical adult Black Rat is 12.75 to 18.25 cm (5.02–7.19 in) long, not including a 15 to 22 cm (5.9–8.7 in) tail.
Behavior
Black Rats are generalist omnivores. They are serious pests to farmers as they eat a wide range of agricultural crops. They are nocturnal and are agile climbers, often inhabiting trees and roof spaces.
Habitat
Black Rats originated in tropical Asia and have spread through the Near East in Roman times before spreading throughout Europe. They are now found worldwide, particularly in urban areas and on ships.
