  • Beaver

    2025-12-05

    The beaver Castor canadensis is the largest rodent in North America and the largest rodent in the world except for the capybara of South America. An adult weighs from 16 to 32 kg and, including its 30-cm tail, a large beaver may measure 1.3 m long. Its ancestors were even larger. In the Pleistocene ice age—the era of the mastodons and the mammoths—the giant beavers that inhabited the expanses of Eurasia and North America measured just under 3 m in length, including the tail, and probably weighed 360 kg.

  • Beluga Whale

    2025-12-05

    Beluga whales have stout bodies, well-defined necks and a disproportionately small head. They have thick skins, short but broad paddle-shaped flippers, and sharp teeth. Unlike other whales, the beluga doesn’t have a dorsal fin. Belugas average 3 to 5 metres in length and weigh between 500 and 1,500 kilograms. Male whales have a marked upward curve at the top of their flippers.

  • Black Bear

    2025-12-05

    The black bear Ursus americanus is one of the most familiar wild animals in North America today. The black bear is a bulky and thickset mammal. Approximately 150 cm long and with a height at the shoulder that varies from 100 to 120 cm, an adult black bear has a moderate-sized head with a rather straight facial profile and a tapered nose with long nostrils. The ears are rounded and the eyes small. The tail is very short and inconspicuous. A black bear has feet that are well furred on which it can walk. Each foot has five curved claws, which the bear cannot sheathe, or hide. These are very strong and are used for digging and tearing out roots, stumps, and old logs when searching for food.

  • Black-Footed Ferret

    2025-12-05

    Of the three species of ferret in the world, the Black-footed ferret is the only one native to North America. They are impeccably cute: cat-like whiskers sprouting from a white muzzle, plush round ears above eyes set into a bandit’s black mask and sturdy legs in black stockings, supporting a sinuous, sandy-coloured body crowned by a black-tipped tail.

  • Blue Whale

    2025-12-05

    The blue whale has a long body with a mottled gray colour pattern that appears light blue when seen through the water. It is the largest animal ever known to exist on earth. It can weigh up to 200 tons and it approximately 80 to 100 feet in length.

  • Canada Lynx

    2025-12-05

    This secretive, hard-to-spot resident of Canada’s boreal forest is likely a descendant of the Eurasian lynx and resembles a very large domestic cat. It has a short tail, long legs, large feet and prominent ear tufts. Its winter coat is light grey and slightly mottled with long guard hairs; the under-fur is brownish, and the ear tufts and tip of the tail are black. The summer coat is much shorter than the winter coat and has a definite reddish-brown cast. The average weight of a lynx is 8 to 14 kilograms, measuring around 90 centimetres in length. The average lifespan is 15 to 20 years.

  • Caribou

    2025-12-05

    The caribou is well adapted to its environment. Its short, stocky body conserves heat, its long legs help it move through snow, and its long dense winter coat provides effective insulation, even during periods of low temperature and high wind. The muzzle and tail are short and well haired.
