The next time you declare that you are “freezing to death,” spare a thought for the wood frog who gets so cold in winter that its heart stops beating – but it does not die.
Winter rest (from the German term Winterruhe) is a state of reduced activity of plants and warm-blooded animals living in extratropical regions of the world during the more hostile environmental conditions of winter. In this state, they save energy during cold weather while they have limited access to food sources.
Other animals able to survive long periods with very little or no oxygen include goldfish, red-eared sliders, wood frogs, and bar-headed geese. [37] The ability to survive hypoxic or anoxic conditions is not closely related to endotherm hibernation. Some animals can literally survive winter by freezing.
Overwintering is the process by which some organisms pass through or wait out the winter season, or pass through that period of the year when "winter" conditions (cold or sub-zero temperatures, ice, snow, limited food supplies) make normal activity or even survival difficult or near impossible. In some cases "winter" is characterized not ...

Most animals move in the direction of their head. However, there are some exceptions. Crabs move sideways, and naked mole rats, which live in tight tunnels and can move backward or forward with equal facility. Crayfish can move backward much faster than they can move forward. Gait analysis is the study of gait in humans and other animals.
Insect winter ecology describes the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds. Unlike those animals, which can generate their own heat internally ( endothermic ), insects must rely on external sources to provide their heat ...
