When winter arrives, we pull out sweaters, mufflers, and our warmest jackets. But animals cannot go shopping or open a cupboard. Yet, they survive temperatures so cold that your ice cream would shiver. Nature has given them incredible winter jackets. Let's take a fun trip through the wild and peek into how animals stay warm in winter.Penguin: Waterproof coat and teamwork

Penguins are the winter superheroes of the Southern Ocean. Their home is so cold that even the wind can freeze water. But penguins walk around like they are wearing the warmest raincoats ever made. Their feathers are packed tightly, overlapping like the tiles on your bathroom floor. These feathers are coated in a special oil that makes them waterproof. So even if a penguin dives into icy water, it stays warm inside its feather coat. But here is the best part. Penguins love teamwork.
