Depends on what you mean by animal. I think Earthworms (which belong to the kingdom of animalia) are a possible candidate. As I've understood it, the common earthworm Lampito can tolerate body temperatures of about 17 Celsius, while the commercial earthworm Perionyx can tolerate body temperatures of about 9 Celsius. Source: http://jeb.biologists.org/cgi/content/abstract/59/3/655 I'm currently searching myself what the lowest temperature a mammal can tolerate is. Edit: it turns out the lowest NORMAL body temperature of any mammal is that of the giant anteater. It also has the greatest variation of normal body temperature, from 33 to 36 C.
The tardigrades or water bears belong to the kingdom animalia and can go in cryostasis. Some can tolerate temperatures very close to the absolute zero, -273 C, temperatures which on earth can only be achieved in the laboratory. However, tardigrades in cryostasis aren't functioning normally. In fact, it's arguable if they're technically alive. Through hypercapnia and hypoxia, nine cats survived to temperatures as low as 12,5 degrees, though this was in the laboratory. Source: http://ajplegacy.physiology.org/cgi/content/abstract/196/2/354

Cheese World
Antarctica??....But to me all winter's are the coldest.......
MESOSPHERE is the coldest layer of the atmosphere.
Antarctica is the coldest of Earth's continents.
The coldest recorded winter in England was the winter of 1962-1963.
The crust is the coldest geologic layer.
the coldest part is the coldest part of Jupiter
the corroboree frog are onlu live in cold climete and they live in Australia. They live in the most coldest part of Australia and they also live in NSW.
No, Neptune is the second coldest planet (Uranus is the coldest.) Mars is the coldest of the four inner planets.
Pluto is the coldest planet
Antarctica is the coldest continent.
coldest
The coldest thing is ice. The coldest country is the south pole.
Russia is the coldest country in the world. The coldest place in the world is Antarctica.
Earth's coldest biome is called the tundra.
Alaska
Antarctica??....But to me all winter's are the coldest.......
because it is in the arctic, which is the coldest place .
