Beavers, otters, and muskrats also make changes for the winter. Resident of channels, ponds, and streams, beavers spend the winter in their sturdy and well-stocked lodges. Beavers usually store enough food to stay put during the chilly months of winter. Otters maintain a hole in frozen lakes through which they can do their fishing. This appears fun for the otters, but is also a useful adaptation allowing them to travel over deep snow in search of food.
Muskrats live in their lodges during the winter, but come out to forage for food.
Their winter diet consists mainly of rootstocks of water plants like cattails, arrowhead, or pondweed. Other lake and pond animals leave during winter months. Frogs, who enjoy balmy shores in the summer, may retire to dens of dried leaves and rubble for the winter. Turtles also migrate from the lake to burrows on land. Insects may bury themselves below ground and enter diaphase, a resting stage where life's activities nearly stop.
