How do fishes survive in ponds even when the atmospheric temperature is well below zero degrees Celsius?

The property of water that allows fish to survive winter's freezing temperatures is that the density of ice (solid water) is less than the density of liquid water. Because of this, the surface layer of water in the lakes freezes, and floats on top of the liquid layer, thus allowing marine life to survive.

Wiki User
∙ 7y agoWater has a maximum density at 4 deg Celsius. When it cools below that the colder layer rises to the surface. If it freezes there, the water below remains in liquid form and to an extent the ice layer prevents the water below it from freezing.

How do vinegar flies survive during winter?
They don't, without the heat necessary (absolute minimum at 4.444444444 degrees Celsius/ 40 degrees Fahrenheit but death can occur at anywhere below 10 degrees Celsius/ 50 degrees Fahrenheit) they slow down and eventually cannot fly, or expend energy on reproduction.
What is the most extreme cold temp an Audad can survive?
the coldest temperature to survive is -78the coldest temperature to survive is -78
What is the coldest temperature cow can survive in?
_ 20 (minus 20 ) is how cold it has to be for a cow to freeze to death
How long can semen survive outside the body?
Normally its assumed that sperms can survive several hours outside body but, the reality is not this. The life and death of sperms depends upon various factors including temperature, environment, humidity etc. So, situation varies from place to place.
Can honeybees fly during hibernation?
In order to fly bees have to keep their body temperature above about 80 degrees Fahrenheit (28 degrees Celsius). As they fly, the flight muscles produce heat, but if the air temperature falls below about 54F (12C) the bee will lose heat faster than it can generate it, so will eventually become unable to fly. When a bee's body temperature drops below about 50F (10C) it will become comatose and eventually die. In colder weather, bees cluster together in the hive and generate heat by vibrating their flight muscles. In the centre of the cluster the temperature will be around 98F (37C). Bees on the outside of the cluster will move in as they cool.
What temperature does sperm survive in?
A sperm can survive at a temperature of between 33 to 35 degrees Celsius.
What is the coldest temperature an ant can survive?
The coldest temperature an ant can survive is said to be as low as -94 degrees Fahrenheit/-70 degrees Celsius. If exposed to freezing temperatures for long enough, an ant will die.
What temperature do frog live in?
Frogs hibernate when the temperature is less than 10 degress Celsius. They can hibernate at temperatures of -7 degrees Celsius at most and can survive in desert temperatures. The highest desert temperature is 49 degrees Celsius, so frogs can probably survive in that temperature. They have a bladder that stores water for them when in HI temperature so they can survive there. They have an ANTIFREEZE chemical element in their body so they can survive in LOW temperatures.
Can humans live in 47 degrees celsius?
47o Celsius = 116.6o Fahrenheit, so this would be a little toasty for humans, but they could survive this temperature for awhile.
Can humans survive at 55 degrees Celsius?
Not very long without water and shade. 55 degrees Celsius is 131 degrees Fahrenheit.
What is one reason a human might survive on venus?
The average surfacetemperature is about 460 degrees Celsius.
What kind of thermoregulate do eels live in?
Eels can survive out of water for at least 15 minutes, they live in the water at a temperature of 17-23 degrees celsius.
Bacteria that cause disease in humans live at what temperature?
The average temperature for a human will be the same temperature the bacteria are likely to flourish at which is about 37 degrees celsius or 98 degrees fahrenheit. However, these bacteria can often survive at a variety of temperatures around this mark, often reaching an optimum temperature a few degrees above this.
Can your body live at 80 degrees Fahrenheit?
80 degree Fahrenheit = 26.7 degree Celsius = 299.8 Kelvin If the outside temperature is as mentioned above, we can survive. This is the temperature in many places.
What temperature can the Arctic fox live in?
Arctic foxes can survive in temperatures as low as -58 degrees Fahrenheit. About -15 degrees Celsius.
What temperature will a mosquito survive in?
Mosquitoes can thrive in any hot temperature, as long as they have a water source to lay eggs in. As far as the cold, mosquitoes can no longer function if the temperature goes below 50 degrees Fahrenheit. However, it has been shown that in Canada, a female mosquito can put themselves into a hibernation and survive temperatures as low as -42 degrees Celsius.
Can your body live at 110 degrees Fahrenheit?
110 degree Fahrenheit = 43.3 degree Celsius = 316.5 Kelvin If the outside temperature is as mentioned above, we can survive. This is the temperature in many places during summer.
