The deep sea angler, known also as Melanocetus johnsoni, is a grotesque-looking fish that lives in the extreme depths of the ocean. Its round body resembles a basketball, and indeed, it looks like it could easily swallow one. It has a large mouth likes with sharp, fang-like teeth. Its appearance has earned it a second name of "common black devil". Despite its ferocious appearance, the angler only reaches a maximum length of about five inches. The angler gets its name from the long, modified dorsal spine which is tipped with a light producing organ known as a photophore. Like many other deep-water fish, the angler uses this organ like a lure to attract its prey. It will flash its light on and off while waving it back and forth like a fishing pole. When the prey fish gets close enough, the angler snaps it up with its powerful jaws. A strange fact about the deep sea angler is the fact that the male is smaller and different in appearance from the female, which is pictures above. The male of the species is about the size of a finger and has small hook teeth, which it uses to attach itself to the female. Once attached, its blood vessels join with that of the female and it will spend the rest of its life joined to her like a parasite, getting all of its nourishment from her body. If the male is unable to attach to a female, it will eventually dies of starvation. The deep sea angler is found throughout the world at depths of over 3000 feet.
