Why fish don't freeze in winter?
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 prevents the water from freezing and also the water below is moving in rivers and oceans

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.
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.
To answer this question, you have to account for many variables. Excluding morphology of the lake and generalizing behavior (as well as species of fish) it is possible for fis…h to die during a freeze. Still, there are many mechanisms that allow for fish to survive these common events. Most fish adjust behaviors, by vertically migrating to allow for the change in temperature or they may migrate from the lake. Other species produce anti-freeze proteins which alter the physiology of the fish. If you need a more in-depth answer, just message me.
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.
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.
due to the anomalous expansion of water
I was learning in my science class in grade 8 that the bottom of the sea bed is warm while the top of the ocean is freezing cold. You could still die if you go to the bottom o…f the ocean, but the temperature dops its coldness a bit so that the fishes can breed. And polar bears arn't friggen fish!
the whole water doesn't freeze (if it's not one of the poles) and fish can survive under that ice in the water because they are immune to really low temperatures.
Antarctica is a continent. In Antarctic waters, which are liquid, the fish survive there because it's their natural habitat. When the sea ice freezes, the fish simply migrat…e so that they remain in liquid.
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!
The Southern Ocean is liquid under its frozen top, and theseanimals are adapted to the extreme cold, some with versions ofanti-freeze in their systems.
White-tailed deer adjust their metabolic rate, home range, and foodsupply in the winter. During the longer summer days, deer have ahigher metabolic rate to take advantage of h…igher quality and moreabundant food supplies. During the shorter days of winter, theylower their metabolic rate and reduce their body temperature. Theysurvive on lower quality food such as white cedar and mountainmaple twigs. They need to eat 6-8 pounds of this reduced nutritionfood. Deer also reduce their home range in winter. They often stay in theshelter of a conifer grove, especially at night. Studies have shownthat night temperatures in these groves are up to 60 degrees warmerthan out in the open. A deer's heavier winter coat, with its hollowhairs, also provides needed insulation against the cold. Deer also match their reproductive cycle to the change in theseasons. They mate in fall. During the early part of theirpregnancy, which occurs during the worst of the winter, the fetusdevelops very slowly and requires very little from the female.During the last trimester, the spring thaw provides more and higherquality browse for the mother such as aspen, willow, and birch. Thefetus then grows rapidly and is born after the snow melts.
When a pond freezes, the ice floats on top of the liquid water underneath. This allows fish to survive beneath the ice during the winter. The ice also acts as a layer of insul…ation, keeping the water above freezing.
