because it's much warmer if the animal ends up outside the water at the wrong moment the combination of frost wet skin and cold bloodedness. will instantly kill it if you have ever swum in bad weather.
All crocodiles are tropical species that unlike alligators, are very sensitive to cold.
By allowing themselves to freeze in place, the gators can lower their body temperatures and slow their metabolisms enough to survive the freezing winter temperatures. Brumation is an innate behavior for reptiles, meaning that their bodies tell them to do it naturally, regardless of environment.
“The normal response of most other crocs when it gets really cold is to come out of the water and try to bask to get warm again.” The alligators could freeze to death if they completely leave the water on a cold day, Ross added.
The “icing” response is tied to brumation, which is basically the reptile version of a mammal's hibernation. By lowering their metabolic rates, becoming lethargic and keeping their snouts above water, alligators are able to survive brief periods of freezing weather.

It's their environmental versatility and physical efficiency that has allowed them to survive mass extinction and two ice ages.
Crocodiles have cold-blooded metabolisms, which means they were able to live for long periods of time in severe darkness, cold, and with very little food.
North American Alligators, which were once nearly extinct, are survivors and can even possibly adapt to modern climate change to survive as they have since ancient times. Cold-blooded creatures that they are, alligators can even survive in water temperatures as low as 40 degrees Fahrenheit.
Crocs typically last between 3 and 5 years with everyday wear. With proper care and less frequent wear Crocs can last for up to 10 years. If used exclusively for indoor wear they can last even longer than this.
If your Crocs seem to be a bit too snug, one way to loosen them up is to dip them in hot water. This will help to expand the material and make them a bit more comfortable. Just be careful not to leave them in the water for too long, as this can cause the material to break down.
The death roll appears to help circumvent the feeding morphology of the alligator. Shear forces generated by the spinning maneuver are predicted to increase disproportionately with alligator size, allowing dismemberment of large prey.
Did you know that the jaws of most crocodiles and alligators can be held closed with a rubber band? Their jaws close with tremendous force and sink into prey with tons of pressure (alligator = 2,980 psi [pounds per square inch] — Crocodile = 5,000 psi), but the muscles that open the jaws are weak.
It's similar to a dog panting to cool down. Crocodilians have evolved to maximize heat gain and minimize water loss. Basically, they can't sweat like we do to cool down. They evolved other methods of cooling, by opening their mouths and essentially sweating through their mouths.
"Its skin is so thick you aren't going to pierce it and its head is a solid mass of bone - there are no weak points. "The one thing you can do is get your fingers in its eyes - but with crocodiles, prevention is always better than cure."
It's just that you don't get that fishy smell you'd expect, even when you scoop a chunk of fish out of their stomach. I've often had my hand right at the esophagus, because they have a waterproof flap in the back of their mouth that you have to hold down when you put the stomach scoop in. And they don't stink.
Wearing Crocs for long periods is not advised by podiatrists. While they may provide great arch support, they are lacking in other areas of support. For example, they do not have enough cushioning at the midsole.
Crocs are made out of a material known as the CrosliteTM. The Croslite is a proprietary resin material produced by Crocs, Inc the manufacturers and distributors of the Crocs brand. The Croslite is neither entirely made of rubber nor does it contain plastic.
Crocs are made from closed-cell resin, a proprietary material that makes them waterproof, lightweight, non-marking and easy to wash. It also gives them that cushiony and comfortable feel that fans love.
Do Alligators Sleep Underwater? Although they won't always do so, alligators may doze off while underwater or partially submerged. They don't typically sleep underwater, at least not for extended periods. Alligators often keep their nostrils tilted up and out of the water to breathe, even when they doze off.
Alligators are dark colored with a broad, rounded snout and are usually found in fresh water. Crocodiles are grayish-green and prefer coastal, brackish and salt-water habitats. They have a narrow, tapered, triangular snout.
3. Like most reptiles, crocodiles are cold-blooded animals and prefer to take up residence in tropical areas close to wetlands. They cannot generate heat on their own, therefore they go into a period of long sleep (or aestivation, a similar state to hibernation) until the weather heats up again.
There are two main reasons. First, crocodiles can live for a very long time without food. Second, they lived in places that were the least affected when the asteroid hit Earth.
Yes, people just like us lived through the ice age. Since our species, Homo sapiens, emerged about 300,000 years ago in Africa, we have spread around the world. During the ice age, some populations remained in Africa and did not experience the full effects of the cold.
Crocodiles relatives are believed to have existed either before dinosaurs or right when dinosaurs first appeared! Crocodile ancestors date back 240 million years to the Triassic period, that's the same era that dinosaurs first began to flourish.
