Water-crisis no more!
Otters aren’t the only adorable creatures on our list. Penguins, those flightless birds that will get into fisty-cuffs with homewreckers, have a very special organ on the top of their heads that converts saltwater into fresh water. It’s known as the supraorbital gland, which can be found directly above the eyes to filter the water.
However, the saltwater they filter doesn’t come from the water it swims in. Instead, saltwater that enters a penguin’s system comes from the fish it eats. Seeing as how tiny a penguin’s body is, it only makes sense that they get rid of as much saltwater from their bodies after gorging on piles and piles of fish.
