The Cnidaria Mammaris or “Sea Boob” is named for its resemblance to the human breast. Endemic to the southern Pacific Ocean, the Sea Boob can grow up to 15ft wide (Bra size WWWW) and is often found in pairs. Under the surface, the Sea Boob has poisonous tentacles like those of a jellyfish that reach to the sea floor, where they entangle bottom dwellers to feed.
Sea Boobs were hunted throughout the 19th century, coveted as an aphrodisiac or just caught and squeezed for pleasure by lonely sailors. They may have played a role in the origin of the myth of mermaids as well.
