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.”

Giant Isopod

Bathynomus kensleyi

The Giant Isopod is an unsettling deep sea creature that crawls along the ocean floor scavenging for animal remains and detritus. These invertebrates are part of phenomenon known as abyssal gigantism, which is the tendency for  deep-sea dwelling invertebrates to be larger than their shallower-water counter parts. The Giant Isopod is found between 310m to 2140m in the ocean.

Cigar Comb Jelly

beroe forskalii

The Cigar Comb Jelly is a gelatinous ctenophore that is marveled by many due to its sparkling bioluminescence. It tends to elegantly float around 120 m in the ocean. It uses unique, hair-like structures called ctens to move horizontally in the ocean. It also swims in a spiral pattern before consuming zooplankton in the ocean.

Fangtooth

Anoplogaster cornuta

The Fangtooth is a ferocious predator that is found at depths between 600 m to 5000 m. It has large, needle like teeth that are used to catch prey. It also has extremely sensitive sensory canals underneath of its scales used to detect movement in the water. Furthermore, their preferred prey are crustaceans and fish.

Periphyllopsis braueri

The  Periphyllopsis braueri is a tiny, deep sea jellyfish that is only 6 cm in diameter. It is red-chocolate  in color, and it has eight gonads. Furthermore, it is found at depths between 600m to 1000m.

Fanfin Seadevil

Caulophyyne jordani

The Fanfin Seadevil is an ugly, deep fish that is covered in gnarled skin and long sensory filaments. The sensory filaments allow this species of anglerfish to detect movement in the water; this helps the Fanfin find and lure its prey. Furthermore, this deformed monstrosity can be found floating between 700m to 3000m in the ocean.

Lav Polyp

leuckartiara octona

The Lav Polypo is a jelly that comes in a variety of colors and shapes; it dwells about 200m in the deep ocean. The red mass inside its translucent bell is the jelly’s reproductive organs. Furthermore, it uses its dull, yellow tentacles can catch unsuspecting prey.

Wolftrap Angler

Thaumatichthys binghami

The Wolftrap Angler is slightly different from many other species of anglers. It has its bioluminescent lure located inside of its mouth instead of connected  to its body. Even though it is intimidating up close, it is only nine centimeters in size. It is found in the deep ocean at 2432m.

Pink Helmet

Aglantha digitale

The Pink Helmet is a mini hydromedusa that comes in a variety of vibrant colors. The tiny jelly is only 4 cm in size and is found towards the surface of the ocean. The purple and blue hues we see in its bell are caused by a phenomenon known as iridescence, when light strikes the jelly’s thin tissue at different angles  (similar to what we see in a soap bubbles). It also has orange pigmentation near its mouth; this pigmentation helps attract prey and mask luminescence. Furthermore, females tend to be more colorful than males.

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.
