While many animal species possess an ability to withstand very low temperatures, the wood frog, also known by its scientific name Rana sylvatica, is the largest animal known to survive up to two-thirds of its body water being frozen.Know More
While frozen, a wood frog can stop breathing and its heart may stop beating for weeks at a time. This process of freezing and thawing out may occur multiple times over the course of a winter.
In addition to the wood frog, the tardigrade, or water bear, is a microscopic organism that can withstand temperatures as low as minus 457 degrees Fahrenheit. This animal is only 1 millimeter in length and can also survive in boiling water, high radiation environments and outer space.Learn more about Polar Bears
Provided a pond does not freeze solid and is of the appropriate depth, goldfish should be able to survive the winter. If the pond is very shallow — such as with a backyard pond — or freezes into one complete block of ice, the fish will freeze and die.Full Answer >
While several animals have evolved to survive in desert climates without the need for much water, the kangaroo rat does not need to drink any water at all. They are able to get the moisture they need from the food that they eat, so additional sources of water are unnecessary.Full Answer >
Polar bears sleep on the open ground, dig pits in gravel and sand at shorelines, or dig shallow areas in the snow or beneath protected ridges. Once inside these protective depressions, they turn their backs to the wind.Full Answer >
Fish can survive in frozen water because only the surface of the water freezes; the fish are able to live life as normal at lower depths beneath the ice. Oxygen is trapped beneath this ice layer, and fish and other creatures living in the water can live quite comfortably despite the frozen surface layer.Full Answer >
