Brittle Stars

Asteroschema Ajax

Brittle stars are in the phylum Enchinodermata and are closely related to sea stars. They have long stringy arms and small podia on the bottoms of their body. They also have a hydrostatic skeleton and have a complex water vascular system. When attacked, they will abandon their arm to confuse predators and make a hasty escape. The photo above is a deep sea brittle star that lives in coral reefs.

Deep-sea white anglerfish

Haplophryne mollis

The Deep-sea white anglerfish is a ghostly white creature found at depths between 1000m to 4000m. The strange bulge between its eyes is a bioluminescent lure. The main fish above is a female and the tiny fish attached to her body are males. Since it is difficult to find mates in the deep ocean, male fish latch onto the female with hooked teeth. Even though the male fish are parasitic, they are eventually reduced to pockets of sperm that are used for reproduction. For all you fellas out there that have a rough time with the ladies, be thankful that you are at least not a bag of gonads floating through the ocean.

It is actually a polychaete (polly-keet) worm species that burrows in the ground as an adult, and floats around the ocean as a baby. The worm feeds itself : by creating a balloon of mucus; collecting particles on the mucus; and then consuming the particles. It is the rarest and thickest worm in the deep ocean, for only ten have been spotted.

Black-devil anglerfish

Melanoncetus johnsoni

The Black-devil anglerfish is a skilled predator that lurks in the darkness. It uses a bioluminescent organ, a top its head, to lure unsuspecting prey into its jaws. Even though these fish are terrifying to look at, they are about the size of a grape fruit. To save energy, they remain immobile in the water, yet they can detect even the slightest vibrations. Since finding a mate is hard at this depth, male fish will attach themselves to a female and slowly dissolve into her tissue; so she is able to use the sperm the male provides at any time. In addition, this is the fish that tried to eat Marlin and Dory in “Finding Nemo.”
