Oh, Blind Cusk Eel. You came into this world without eyes, you’ve traded in scales for slippery gelatinous skin, and you live 2,000 to 6,000 metres below the surface. You are the junk of the ocean (in more ways than one), but we love you all the same.
Most likely to: continually bonk its head on the ocean floor, just trying to find a friend.
