Moose are the largest members of the deer family and one of the largest land mammals in North America. Adults may stand as tall as 2.3 m high. Males are larger than females and possess elaborate, widened antlers that can measure up to 2 meters in total width, from tip to tip. These are the largest antlers carried by any mammal, worldwide. They are shed and re-grown annually. Males range from 2.5 to 3.2 meters in total length, females from 2.4 to 3.1 meters. Males weight from 360 to 600 kg and females from 270 to 400 kg. Moose have thick, brown fur that ranges from light to almost black in color. Individual hairs are 15 to 25 cm long and hollow, resulting in excellent insulation. Moose are also distinguished by their long head with a long, flexible nose and upper lip. Moose have very long legs and a dewlap of skin on the throat.
Moose generally live in forested areas where there is snow cover in the winter, and prefer moist conditions where there are lakes, ponds, and swamps. They are found in areas with snow cover up to 60 to 70 cm in depth during the winter, although deep, crusted snow makes them vulnerable to predation by wolves. Moose are limited to cool regions because of their large bodies, inability to sweat, and the heat produced by fermentation in their gut. They cannot tolerate temperatures that exceed 27 degrees Celsius for long. In summer moose seek shade and cool themselves in ponds and streams.
I took a picture of this moose swimming in Grand Lake, NB, Canada. It came ashore in the backyard of my cottage.
