What is the maximal age a Yellow-bellied marmot reaches?
An adult Yellow-bellied marmot (Marmota flaviventris) usually gets as old as 8 years.
Yellow-bellied marmots are around 30 days in the womb of their mother. When born, they weight 33 grams (0.07 lbs) and measure 11.1 cm (0′ 5″). As a member of the Sciuridae family (genus: Marmota), a Yellow-bellied marmot caries out around 4 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 41.2 cm (1′ 5″).
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 yellow-bellied marmot (Marmota flaviventris), also known as the rock chuck, is a large, stout-bodied ground squirrel in the marmot genus. It is one of fourteen species of marmots, and is native to mountainous regions of southwestern Canada and western United States, including the Rocky Mountains, Sierra Nevada, and Mount Rainier in the state of Washington, typically living above 6,500 feet (2,000 m). The fur is mainly brown, with a dark bushy tail, yellow chest and white patch between the eyes, and they weigh up to approximately 5 kg (11 lb). They live in burrows in colonies of up to twenty individuals with a single dominant male. They are diurnal and feed on plant material, insects, and bird eggs. They hibernate for approximately eight months starting in September and lasting through the winter.
