Il modo bizzarro e totalmente scientifico in cui gli alligatori respirano l'acqua gelida

Le tempeste invernali hanno colpito gli Stati Uniti questa settimana, and many animals are struggling in the cold.

L'alligatore a sangue freddo, anche se, sta attraversando la settimana con un insolito metodo di sopravvivenza.
Questa settimana, an employee at the Oklahoma Department of Wildlife Conservation posted fotografie of alligators frozen in water. A grim scene, può essere — if their snouts weren’t sticking out.
It’s calledicing,” and it’s how alligators breathe when submerged in freezing temperatures.
    While they may look dead in photos, they’re survivingand in the middle of a fight of their lives.

    What is ‘icing’?

    Il “icingresponse 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 pagina Facebook.

    The gators won’t freeze if the water stays liquid,” he said in a comment. “Their snouts are just cartilage so freezing doesn’t hurt their snoutsThey 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 solidwithout even a heart beatuntil it’s safe to thaw themselves.
      Red bats, d'altra parte, 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.
