Snails
Living on land or in the water, snails are gastropods that in some cases can grow up to 30 centimetres long (ugh). Notorious for their slime trails, researchers have found these may actually have some surprising uses, as antioxidants that can also reportedly regenerate human skin and act as all-natural wound-healers.
Adélie penguins
Forget about buying the love of your life a diamond ring. If you’re a male penguin, what you’re really interested in finding is a pebble to lay at the feet of your beloved. This gift has a practical purpose, though. The Adélie species of penguin make their nests out of pebbles and rocks, to keep the eggs inside safe from melting snows.
Emperor penguins
There’s something so joyful about the site of a bunch of penguins jumping into the air before plunging from the ocean onto the ice. Here again, penguins are eminently practical. According to BBC’s The Blue Planet, just before they make this little move “they release air bubbles from their feathers. This cuts the drag on their bodies, allowing them to double or triple their swimming speed quickly and launch into the air.”
