Alligator

Shallotte River Swamp Park

The Shekel notes that there are now big alligators in Michigan. Michigan? Isn't it a little cold for gators? As The Dodo explains, evidently not:

North Carolina’s Shallotte River Swamp Park is home to 12 alligators rescued from captivity. As the recent extreme weather system moved through the area, the water they inhabit froze over.

So, rather than allow themselves to get trapped under the ice, or risk freezing in the colder air above, the alligators did this instead.

They protruded just the tips of their noses through the surface as it iced over, allowing themselves to breathe while remaining mostly submerged.
