Basket Star
Gorgonocephalus caputmedusae
The Basket Star is a strange yet elegant creature that lives in the deep ocean. It resembles a flesh white ball with gnarled and swirling branches. It thrives in locations with strong currents. Its numerous arms move slowly and wrap around prey. They are one of my favorite animals from the Echinodermata phylum.

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.

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.

Scaly Dragonfish
Stomias Boa
The Scaly Dragonfish is about 32cm long and found at depths between 200 to 1500m. The long purple barbel on its chin is used to lure in prey. When the pery gets close enough, it swings its jaws forward swallowing the prey whole.

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.

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.

Pyrodinium bahamense
Pyrodinium bahamense is a tropical species of dinoflagellates that is found primarily in Atlantic Ocean waters. It prefers salinity around 20 psu and blooms when there are large amounts of nitrogen in the water. The dinoflagellate glows bright blue when agitated by motion. Furthermore, even though this plankton species is beautiful to look at, it causes seafood toxicity.

Sea elephant
Carinaria japonica
The Sea Elephant is a translucent sea snail that has a large muscular body and a tiny triangular shell. Its foot is used for crawling on the ground, and it can be transformed into a fin that is used for swimming. It is called the “sea elephant” because it has a small trunk in its mouth that is used to swallow prey. Furthermore, the Sea Elephant eats arrow worms and jellies.

Hi everyone, thank you for supporting my blog. I have gained over 500 followers and that is worth celebrating. I will try my best to post every day some of the amazing creatures that live in the deep ocean. Have a great night!
Physonect Siphonophore
Nanomia cara
The Physonect siphonophore has tiny, bubble shaped sacs that are filled with gas. The sacs are called pneumatophores and help this creature move through the deep ocean. It also has venomous tentacles that stun prey and over eighty stomachs. There are numerous amounts of these strange creatures along the east coast, and they have cause some fisheries to collapse. Furthermore, they can be found at depth between 400m to 1000m.

Sea Gooseberry
Pleurobrachia pileus
The Sea Gooseberry is a comb jelly or ctenophore that has two enormous tentacles covered with adhesive cells. When tiny crustaceans, eggs, and larvae brush against the tentacles, the prey are stuck to them. The Sea Gooseberry draws the tentacles to its mouth, and it consumes the prey. These unique organisms can be found as deep as 750 m.
Black Dragonfish
Idiacanthus atlanticus
The Black Dragonfish are needle-like fish that migrate between 500m and 2000m in the deep ocean. Females are black with 6 stripes and lack a barbel, pelvic fins, and sharp teeth. Males, on the other hand, are dark brown and have a barbel, which is the light producing structure on its chin. Furthermore, it uses bioluminescence to detect prey instead of lure 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.

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.

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.
