Why don't deer freeze to death in winter?
White-tailed deer adjust their metabolic rate, home range, and food supply in the winter. During the longer summer days, deer have a higher metabolic rate to take advantage of higher quality and more abundant food supplies. During the shorter days of winter, they lower their metabolic rate and reduce their body temperature. They survive on lower quality food such as white cedar and mountain maple twigs. They need to eat 6-8 pounds of this reduced nutrition food. Deer also reduce their home range in winter. They often stay in the shelter of a conifer grove, especially at night. Studies have shown that night temperatures in these groves are up to 60 degrees warmer than out in the open. A deer's heavier winter coat, with its hollow hairs, also provides needed insulation against the cold. Deer also match their reproductive cycle to the change in the seasons. They mate in fall. During the early part of their pregnancy, which occurs during the worst of the winter, the fetus develops very slowly and requires very little from the female. During the last trimester, the spring thaw provides more and higher quality browse for the mother such as aspen, willow, and birch. The fetus then grows rapidly and is born after the snow melts.

Fish go further down than the ice. The ice usually doesn't freezeall the way to the bottom. If the fish are trapped in shallow wateror if the lake or stream freezes to the bot…tom, they will freeze.
Birds actually use several tricks to keep their legs from freezing. First they can stand on one leg and pull the other up under their feathers when one leg starts getting too …cold. And if it gets really cold, they can squat to cover both legs with breast feathers. If you see a bird doing this, they may be getting uncomfortably cold legs. Also birdsâ feet are mostly bone and tendons, so unlike mammals, they have a limited supply of nerves, blood vessels or muscles to freeze. Their feet are also covered with scales which isnât a living tissue and less susceptible to freezing. Finally, birds donât have sweat glands in their skin to produce any moisture to freeze. Heat and moisture are accumulated in sacs, transferred to the lungs and eliminated through the mouth. No moisture escaping through their feet is also the reason they donât stick to metal perches in the winter.
Frogs hibernate during winter months in all states. They burrowthemselves in the dirt and sleep until spring time.
Part of the answer is that their fur helps trap heat close to their body. Secondly, their skin is black which helps absorb rays from the Sun that do reach the north pole. And …lastly, a healthy dose of body fat provides insulation to keep their internal organs warm.
They have feathers to keep them warm and their nests aresurprisingly warm some birds even migrate to warmer countries forthe winter
During the Winter, squirrels hibernate. By hibernating, the squirrels lower their heart rate and are immune to the cold. Before hibernation, they stock up on food for the Wint…er.
The oceans are saline or salt water. This affects the temperature at which they freeze. Plain water freezes at about 0Â°C at sea level, but saline, at the concentrations nor…mally found in the ocean, freezes at close to -2Â°C. Pressure also affect freezing temperature. The deep ocean is at great pressure, so even though it can be at temperatures of -3Â°C it does not freeze. The temperature of the surface of the ocean varies from about -2Â°C to about 34Â°C depending on currents and latitude. Much of the surface of the Arctic ocean is frozen all year round, but the extent varies during summer and winter. An area of the sea around Antarctica also forms sea ice in winter each year, but much less area is permanently frozen than in the Arctic.
A dogs nose does not freeze in the winter because it contains ablood flow. It may not also freeze because there is warm air thatgoes in and out of it at all times.
GIVE THEM PLENTY OF HAY, AND AN adaquete shelter.
If you don't insulate water pipes or protect them in some way from the cold, the water inside the pipes can freeze. This causes you to be without water until the pipes warm up… enough to thaw. Also, when the water freezes, it can expand and burst the pipes which will then need to be replaced. Save yourself the aggravation of having no water and the cost of replacing pipes by insulating them. To protect pipes in an empty or unused building, you can pour anti-freeze down all drains and in the toilet to winterize them.
Rivers don't freeze in the winter because the water keeps moving and doesn't freeze.
As a deer farmer, I was wondering the same question. I have found that their think fur and hide is enough to keep them warm, eventhough they have skinny legs.
In Polar Bears
Animals such as the polar bear, penguin, walrus, etc., are adapted to cold weather by means of thick layers of body fat, in addition to very warm fur or feathers, which insula…te them from the cold.
Seals have a thick layer of fat around their bodies, plus oily, waterproof fur to help insulate them.
While squirrels may sleep in a protected area such as a hole in a tree, I'm not aware that they hibernate. I live in Northern MN and we have had overnight temps in the -23 to …-28 range the last few nights this January and the squirrels are right back under the feeders the next day. As long as there is food around, I will see squirrels daily!
because the ice on top of the water has little atoms stick to each other and sir gets grapes in side between the atoms which makes ice flot on top of the water and that preven…ts the water from freezing and also the water below is moving in rivers and oceans
Emperor Penguins do not freeze to death in the Antarctic as they are well adapted to their surrondings. A penguin doesn't freeze to death because: . It has a thick layer of… blubber or fat to keep it warm . It has black skin which is good at absorbing and keeping in heat . A penguin's Feathers are tightly compact and when a penguin 'preens' itself by putting a special oil made from a gland in its tail on it, it becomes Waterproof. . When penguins do get cold, they huddle together for warmth. To you or I it i cold in the Antarctic but to a Penguin, it is normal as it has adapted to the cold weather, just as we have adapted to our surrinding
