How old does a Brown bear get? (age expectancy)

What is the maximal age a Brown bear reaches?

An adult Brown bear (Ursus arctos) usually gets as old as 50 years.

Brown bears are around 225 days in the womb of their mother. When born, they weight 500 grams (1.1 lbs) and measure 12.9 cm (0′ 6″). As a member of the Ursidae family (genus: Ursus), their offspring is 2 babies per pregnancy. Fully grown, they reach a bodylength of 1.49 meter (4′ 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.

The brown bear (Ursus arctos) is a bear species found across Eurasia and North America. In North America, the populations of brown bears are called grizzly bears. It is one of the largest living terrestrial members of the order Carnivora, rivaled in size only by its closest relative, the polar bear (Ursus maritimus), which is much less variable in size and slightly bigger on average. The brown bear’s range includes parts of Russia, Central Asia, China, Canada, the United States, Hokkaido, Scandinavia, the Balkans, the Picos de Europa and the Carpathian region, especially Romania, Bulgaria, Anatolia and the Caucasus. The brown bear is recognized as a national and state animal in several European countries.While the brown bear’s range has shrunk and it has faced local extinctions, it remains listed as a least concern species by the International Union for Conservation of Nature (IUCN) with a total population of approximately 200,000. As of 2012, this and the American black bear are the only bear species not classified as threatened by the IUCN. Populations that were hunted to extinction in the 19th and 20th centuries are the Atlas bear of North Africa and the Californian, Ungavan and Mexican populations of the grizzly bear of North America. Many of the populations in the southern parts of Eurasia are highly endangered as well. One of the smaller-bodied forms, the Himalayan brown bear, is critically endangered, occupying only 2% of its former range and threatened by uncontrolled poaching for its body parts. The Marsican brown bear of central Italy is one of several currently isolated populations of the Eurasian brown bear, and believed to have a population of just 50 to 60 bears.
