How old does a Muskrat get? (age expectancy)

What is the maximal age a Muskrat reaches?

An adult Muskrat (Ondatra zibethicus) usually gets as old as 10 years.

Muskrats are around 27 days in the womb of their mother. When born, they weight 22 grams (0.05 lbs) and measure 5.1 cm (0′ 3″). As a member of the Muridae family (genus: Ondatra), a Muskrat caries out around 6 little ones per pregnancy, which happens around 2 times a year. Fully grown, they reach a bodylength of 27.7 cm (0′ 11″).

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.

A Muskrat gets as old as 10 years

The muskrat (Ondatra zibethicus), the only species in genus Ondatra and tribe ondatrini, is a medium-sized semiaquatic rodent native to North America and an introduced species in parts of Europe, Asia, and South America. The muskrat is found in wetlands over a wide range of climates and habitats. It has important effects on the ecology of wetlands, and is a resource of food and fur for humans.The muskrat is the largest species in the subfamily Arvicolinae, which includes 142 other species of rodents, mostly voles and lemmings. Muskrats are referred to as “rats” in a general sense because they are medium-sized rodents with an adaptable lifestyle and an omnivorous diet. They are not, however, members of the genus Rattus.
