There is a deep sea creature that can't do anything but have sex!


The Pacific blackdragon haunts the depths of the ocean, its black snake-like body lit up by photophores along its belly.

When it opens its mouth, it reveals a set of long, dagger-sharp teeth. Hanging off the lower jaw is a barbel tipped by a glowing lure that can be moved to entice prey to venture within reach.

The Pacific blackdragon is black on the inside as well as the outside, its black stomach preventing light from swallowed bioluminescent prey shining out. Male Pacific blackdragons are only about a quarter the size of the females, and males can’t do anything but mate.

The young fish are similar in shape to the adults, but their eyes stick out on very long stalks. The stalks are absorbed as the fish grows and the eyes eventually come to lie in their sockets.
