Blacksnout Seasnail
Paralipparis copei copei
The Blacksnout Seasnail may not look like a snail, but it does have a slimy, gelatinous substance that covers its body. It can be found at depths between 200 m to 1692 m, and adults grow up to be 17 cm in size (approximately 6.5 in). It also has an elongated body that resembles an eel. Furthermore, it can be seen rolling itself in a loop; this behavior is a defensive posture that makes it appear like a jelly. In the darkness, predators tend to avoid the Blacksnout Seasnail because its often mistaken as a hunter due to its appearance and behavior.
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.

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.

Squarenose Helmetfish
Scopelogadus beanii
The Squarenose Helmetfish is found between 800m to 4000m in the ocean. It received this unique name due to its scales reminding scientists of an armored helmet worn by medieval knights. It also has unusual holes around its face, and the white strands covering its face are sensory canals.

Pigbutt worm
Chaetopterus pugaporcinus
The Pigbutt worm or the flying buttocks of the sea is spotted floating between 965 m to 1300 m in the deep 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.

Mid-water Arctic Hydrozoan
Botrynema brucei
The Mid-water Arctic Hydrozoan is a mini-jelly that is transparent with hints of blue. It thrives in freezing cold temperatures and drifts aimlessly in the Artic Ocean. Moreover, it is only 3 cm in size and floats between 900m to 2,600m.

Cockatoo Squid
Galiteuthis phyllura
The Cockatoo squid is a highly-specialized oddity of the deep ocean and found at depths between 300 to 1400 m. It is completely transparent, except for its eyes. It also has bioluminescent photophores that are directed downward: this makes it difficult for deep sea predators to see the Cockatoo Squid. It was named after the Cockatoo because it holds its tentacles above its head, resembling the bird. The Cockatoo squid can also get fairly large with adults reaching lengths of 2.7 meters (over 6 ft.)

Threadfin Snailfish
Careproctus longifilis
The Threadfin Snailfish resembles a prehistoric tadpole that is ghostly white. The holes in its face are large sensory pores that help them detect changes in the ocean. It is often found at depths between 1900 to 2997 meters.

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 Bell Jelly
Scrippsia pacifica
The Giant Belly Jelly has 256 tentacles attached to a gelatinous bell-shaped base. Like most cnidarians, the Giant Belly Jelly uses specialized stinging cells called nematocysts to catch its prey. When fish and other prey swim into its tentacles, the sensory projection on the cnidocyte (cell that holds the nematocysts) is activated. Then the nematocysts and barb are released, hitting the vulnerable prey and releasing a toxin into the prey’s body. The Giant Bell Jelly is found at 400 m in the ocean. It is related to the jellyfish, but it is categorized as a Hydrozoa (similar to the Portuguese- man-o-war)

Bioluminescence is a chemical reaction that produces light. Many deep sea animals use bioluminescence. This blog is dedicated to educating the public about the amazing creatures that thrive in the deep sea.
