Did Crocodiles Descend From Dinosaurs?
Mar 09, · Crocodiles are built to last. Evolving around million years in the Mesozoic epoch, crocodiles have far outlived the dinosaurs. Scattered across more than 90 countries, 23 species of the Crocodylia order haunt freshwater rivers, streams and marshes. Those 23 crocodilian separate into three families: alligatoridae (alligators and caimans), crocodylidae (crocodiles) and gavialidae (). The wildernesses of our world have seemed to constantly call out to the adventurous, luring them in with the promise of thrills, adventure and an escape from modern society. It is in some people’s nature to want to go out into the wilds and live a simple life, to shuck off modern conveniences and get Read more».
CNN It's how long do bed bug bites take to heal just humans finding ways to stay warm during this week's historic temperature plunge — our animal friends are too. What happens to Denali's wood frogs in the winter? Hubbard pic. Don't forget about your furry friends during this historic arctic plunge. While wild animals can adapt, our pets can do so as easily!
Penguins stay warm through social thermal regulation, a scientific term for cuddling. And some of the strategies animal use are pretty cool pun fully intended. Animals are classified as either endotherms or ectotherms, which is another way of saying warm-blooded or cold-blooded. Endotherms regulate their body temperature by producing heat within. Birds are a good example. Ectotherms are the opposite and rely primarily on the surrounding environment to regulate body temperature.
Picture a turtle on a log basking in the sunshine on a warm day. Every animal, whether it's an endotherm or ectotherm, has a plan to survive the cold, said Justin Boyles, a thermoregulation expert and an associate professor at Southern Illinois University in Carbondale, Illinois. Some animals migrate before the season to avoid it altogether. Some conserve energy and hibernate until its source of food returns during the warmer months. And others have developed ways to just tough out the harsh conditions that sometimes hit.

What alligators do during extreme cold seems straight from a science-fiction movie. Alligators go into brumation during the cold, which is like a low-scale, short-term hibernation to conserve energy and maintain its body temperature. What's weird about that? When it gets freezing cold, an alligator will stick its nose out of the water to breathe like its snorkeling the beautiful blue waters of the Bahamas.
That is what's eerie. You may remember viral images of this alligator from a cold snap in Red bats look a lot like leaves when hanging from a tree. During the cold, a red bat will drop to the ground and cover itself with a litter of leaves like a blanket.
Given its outer appearance, it's camouflaged quite well and protected from predators. So, it can sleep peacefully. Manatees are extremely susceptible to the cold.
A sea cow can't survive in water temperature below 68 degrees Fahrenheit, according to Manatee Lagoon spokeswoman Brittany DiLoreto. When temperatures begin to drop, manatees will take a vacation to Florida — curling up in the Sunshine State's rivers and springs, and surprisingly, even the warm, clean waters of nearby power plants.
Penguins stay warm through social thermal regulation. This means Mumble from "Happy Feet" and all his friends are huddling and cuddling together to stay warm. Boyles, the thermoregulation expert, says normally vicious flying squirrels will sometimes show a softer side and huddle with others to make it through a cold snap.
But pets are different. They need help. Through hundreds and hundreds of years of domestication, most pets have lost the ability to adapt to harsh conditions like wild animals. It's important that pet owners take the necessary steps to protect their four-legged family members during the cold, especially when temperatures drop below freezing.
The Animal Humane Society of Minnesota offers the following suggestions for protecting your indoor and outdoor pets during harsh winter conditions:. During severe weather, dogs should go outside only to relieve themselves and cats should be kept indoors at all times.
Remove any ice, salt and caked mud from your pet's paws and fur immediately. Check to see if your pet's bed is in a cold or drafty area of your home. If it is, move it to a warmer location. Feed your dog reduced portions to avoid weight gain. Indoor dogs typically receive less exercise during cold weather and therefore may require fewer calories.
Outdoor pets typically need more food in cold weather because they must burn more calories to keep warm. Check your pet for frostbite, how to create an infopath form 2010 on paws and ears, and make sure your pet's water is never frozen. Clean up all antifreeze spills. One lick of the sweet-tasting fluid can be fatal to an animal. Before starting your car's engine, knock on the hood as cats have been known to climb into engine compartments for warmth.
Keep an eye out for signs that your pet is experiencing hypothermia. Symptoms include a weak pulse, dilated pupils, decreased heart rate, extreme shivering, pale or blue mucous membranes, body temperature below 95 degrees, stupor and unconsciousness.

Jan 17, · This is how alligators survive an icy winter: they stick their noses out and let the water freeze solid around them. Photo Credit: Shallotte River Swamp Park. Huffington Post, David Lohr. A viral video of alligators frozen in an icy pond at North Carolina’s Shallotte River Swamp Park has been the talk of social media, with many people wondering whether coldblooded crocodilians can survive in brutally . Nov 26, · Alligators have two options when dealing with the cold. First, alligators can excavate a den and hibernate until spring, or they can submerge themselves almost completely underwater with only their nostrils above water. This tactic is known as the “icing response”. As the surface freezes, the alligator’s upper body is trapped within the ice. Feb 20, · By lowering their metabolic rates, becoming lethargic and keeping their snouts above water, alligators are able to survive brief periods of freezing weather.
Don't worry -- this alligator is alive. During cold weather, gators stick their snouts above water to keep breathing while lowering their metabolic rates. The cold-blooded alligator, though, is getting through the week with an unusual method of survival. This week, an employee at the Oklahoma Department of Wildlife Conservation posted photos of alligators frozen in water. A grim scene, maybe -- if their snouts weren't sticking out.
Cuddling penguins and snorkeling alligators: What animals do to stay warm during extreme cold. It's called "icing," and it's how alligators breathe when submerged in freezing temperatures. While they may look dead in photos, they're surviving -- and in the middle of a fight of their lives.
Read More. What is 'icing'? 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. As cold-blooded reptiles, alligators rely on their external environments for temperature regulation, which means cold weather is not conducive to their survival. David Arbour, with the Oklahoma Department of Wildlife Conservation, posted photos of alligators icing to his Facebook page.
They can still move and are aware of things. Alligators aren't the only animals with unusual survival tactics. Animals are weathering the freezing temperatures in different ways. Take the wood frog: In the winter, they are able to literally freeze solid -- without even a heart beat -- until it's safe to thaw themselves. Red bats, on the other hand, leave their elevated roosts and hit the ground in freezing weather. They cover themselves with leaves like a blanket, comfortably camouflaged from predators.
Alligators may not be unique in their fight for survival, but you can definitely add this to the list of cool things they do.
