how do fish stay alive,in wildlife,during the winter?

Many survive the same way reptiles and amphibians do. They hibernate by digging into the mud and burying themselves within. Others are capable of surviving in low-temperature water. The rest migrate like birds.

Salt water fishes needs to be in salt water. And fresh water fishes needs to be in fresh water. Salt water fishes can survive in fresh water for short amount of time. It's been known to see sharks in fresh water. I think it helps remove stuff from their skin.

They don't swallow the water, per se - they simply swim and let the water flow past their gills.  As the water flows throughout the network in their gills, the oxygen that's dispersed throughout the water enters their bloodstream, thus enabling the fish to breathe underwater!\n\nThis is why when one purchases a fish tank, one has to get an oxygen supplier as well - no fish can survive in just standing water for long!

Penguins have a special patch on their body that secretes oil. They use this oil to waterproof themselves so that they are less effected by the chilly waters.\nEmperor Penguins have developed a system that allows all of them to stay warm. They all huddle in one big group, which conserves their body temp. They cycle through which penguin gets to be on the inside and which on has to be on the outside. \nPenguins also have thick layers of fat that insulate them.

It depends on the insect. Some die off leaving eggs behind to hatch next season (like the Praying Mantis). I have heard some critters replace the water in their bodies with glycerin so they don't freeze during the cold months.

Fish don't hold thier breath

No the do not sleep. Sunnies and Northerns and perch sink near the bottom, and remain somewhat dormant. Bass may actually remain active at night and can easily be caught with floating rapalas reeled slowly across the water.\n\nTake a bright flashlight and walk along the shore shining the light into the shallows, and you will be amazed at the things you can see.

some animals in winters sleep ie the whone winter they sleep n this is not actual sleep but actually they appears dead ie no motion of body .There is no movement and it takes a long time for it to wake up enough to even walk around.before hibernation \nDuring the fall, hibernating animals eat more food than usual.  Their bodies will live off their body fat as they ‘sleep’ through winter.  The animal will use up the body fat it stores and not lose any muscle.  This causes the animal to come out of hibernation thinner but still as strong as it was in the fall.

Its their feathers keeping them warm, but havent you been wondering about something else?\n\nWhy is it that ducks feet dont freeze to the ice?? Huh??? :p

It's impossible to answer. Some fish are predators, some live entirely on fruit and nuts, some fish live on mud, some live on plankton, some on microscopic algae.\n\nSome fish eat only jellyfish, or just a single species of algae and won't touch anything else. Other fis will eat anything that moves to slow whether it's a baby crocodile, a dead elephant, a lettuce leaf, slime scraped off the rocks or just a pile of mud.\n\nTo discuss the nutritional requirements of fish in even the most basic detail would take several years and result in a several books.\n\nYou will need to narrow down what fish species you are asking about to get any sensible answers.

Because fishes are cold blooded animals....sweating is a way for regulating temperature that is often employed by mammals.

They slow down dramatically. \n\nThe animal's metabolism slows so everything else in it's body slows. \n\n\nFrom source:\n  When an animal begins to hibernate, its body temperature drops very low so that it almost matches the temperature outside.   Your temperature is normally about 98.6 degrees Fahrenheit.  If you were a hibernator and it was 30 degrees outside, your body temperature would drop from 98.6 down to about 30-40 degrees. THAT’S cold! \n    The animal’s heartbeat and breathing slow down, too.  This is when that stored fat that the animal packed on in the fall comes in handy.  This stored fat lasts longer because their bodies are slowed down so much that they don’t need much energy.  This is how the animal makes it through the whole winter on the fat it has stored in its body.  This is why it's important for animals to get enough food stored in the fall.  If there is a shortage of food at that time, the animal might not live until spring when it can find its food again.

Yes. Fish that live in saltwater lose moisture from their bodies through osmosis. These fish need to drink lots of water, or they'll become dehydrated. The extra salt is then simply excreted.

In cold running water frogs can stay underwater indefinitely, certainly for many days if required. \n\nThere are several species of frogs and toads that live their entire lives underwater and never need to surface for air. Such species may go for several years without taking a breath, instead absorbing all their oxygen through their skin.

It depends on the fish...Walleye, who are extremely sensitive to light and movement, tend to prefer cloud cover and darker days.\n\nMany fish swim deeper as currents in the lake change due to weather, they do this especially around the time when the cold water from the bottom rises and the warms water sinks (early spring, late fall). Fish especially hate thunderstorms, and it nearly impossible to catch them after storms for a day or two.\n\nNot sure about ocean fish, though
