Document Summary
Moose have very long legs 2m high at the shoulder. Snowshoe hares: huge hind feet, large surface area of feet. Many northern animals also have large hind feet: marten & fisher (northern weasel) Ruffed grouse grow snowshoes every autumn: grow scales on the sides of their toes and by the summer they"ve gone from being worn down. Small mammals travel through the subnivean space. White-tailed deer move to a yard (sheltered area w/ less snow & more food: browse line identifies where white-tailed deer feed in winter. Wolves also have a behavioural adaptation: travel in single file & put their feet where the one in front has already broken the snow, long legs. Otters have short legs: they slide on their bellies toboggan , mink can also use their bodies as toboggans. Animals solve the sub-zero temperature in a number of ways. But not all animals stay & face the challenges.
