Glass Octopus
Vitreledonella richardi
The Glass Octopus spend its entire life in the midwater section of the ocean and found at depths between 200m to 2000m. Even though it has no protection from predators, it achieves perfect transparency. The only part of the Glass Octopus that is visible is its digestive gland. However, the digestive gland is placed vertically to minimize detection. In addition, I find this octopus to be super cute!

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)

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.

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.

Glowing sucker octopus
Stauroteuthis syrtensis
The Glowing Sucker Octopus can be found at 2500 m in the deep ocean. This unique creature has two fins that look similar to elephant ears. They move elegantly through the water by moving these fins and contracting their mantle. Evidence of this creature has only been spotted in the Atlantic Ocean.

Piglet Squid
Helicocranchia pfefferi
The Piglet Squid is a very small and delicate, transparent squid. It is found at depths between 400 to 1000 m. It has an unique siphon that is used for jet propulsion and it resembles a pig muzzle. The young piglet squids tend to live close to the surface, and steadily migrates downward as they grow. This behavior is called ontogenetic migration.

Hi everyone, I apologize for the inconsistent posting. I’ve been studying for my Chemistry Praxis. :( There will be more to come soon !
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.

Marrus orthocanna
Marrus orthocanna is a deep sea siphonophore found at depths between 400m to 2200m. It has a colony of gas-filled zooids on the top used for locomotion. It also has a long, bright orange tentacles on the bottom. Marrus orthocanna are viscous predators and consume small crustceans and copepods.

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.

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.)

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.
