What is the maximal age a Black rat reaches?
An adult Black rat (Rattus rattus) usually gets as old as 4.17 years.
Black rats are around 23 days in the womb of their mother. When born, they weight 4 grams (0.01 lbs) and measure 4.2 cm (0′ 2″). As a member of the Muridae family (genus: Rattus), a Black rat caries out around 5 little ones per pregnancy, which happens around 3 times a year. Fully grown, they reach a bodylength of 19.4 cm (0′ 8″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
The black rat (Rattus rattus), also known as ship rat, roof rat, or house rat—is a common long-tailed rodent of the stereotypical rat genus Rattus, in the subfamily Murinae.The black rat is black to light brown in colour with a lighter underside. It is a generalist omnivore and a serious pest to farmers because it feeds on a wide range of agricultural crops. It is sometimes kept as a pet. In parts of India, it is considered sacred and respected in the Karni Mata Temple in Deshnoke.
