Moose have big-muscled bodies, but their legs are long and thin. This helps them walk through deep snow in winter and wade in ponds and lakes, where they forage for plants during spring and summer. Their average weight is 400 kilograms for a male; 350 kilograms for a female and their average length is 2.4 metres to 3.2 metres. Their average lifespan is between 15 to 20 years in the wild. Moose have been known to dive up to 5.5 metres or more to feed on plants at the bottoms of lakes.
