Flashy red-and-black stripes on its beak are the source of this bird's nicknames: "clown of the sea" and "sea parrot." But the bold color pattern on the beak of the Atlantic puffin is only the beginning of what makes this beak so special. There are serrations on the upper mandible, so the puffin can carry more than 10 fish at once by holding them with its tongue against them.
