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.)

Crystal Jellyfish
Aequorea victoria
The Crystal Jellyfish is a graceful, transparent jellyfish with long, thin tentacles. It has bioluminescent organs around it bell that produce a bright, green light. It tends to consume small copepods, but it has the ability to swallow other jellyfish half its size. Furthermore, this jelly is used in biological experiments to detect calcium.

Red Paper Lantern Medusa
Pandea rubra
The Red Paper Lantern resembles a floating, Japanese paper lantern in the deep sea. It has the ability to crumple and wrinkle its bright, red bell, and it is located at depths between 550m to 1200m. It has also been nicknamed the “origami jelly.”

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.

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.

Pram Bug
Phronima sedentaria
The Pram Bug is a deep sea amphipod that is located between 200 to 1000m in the ocean. It has a translucent exoskeleton and can see primarily blue light. It is also is contained in a hollowed out barrel that is used for protection and to house babies. The image above is a female pram bug carrying its young.

Black- eyed squid
Gonatus onyx
The Black-eyed Squid is roughly over one foot (35 am) and is found at depths as deep as 2500m. The female Black-eyed Squid works fiercely to protect her babies, by carrying around a patch of egg for six to nine months. When the eggs hatch, 2000 to 3000 babies are released into the ocean. However, this makes her vulnerable to predators.

Barnacle Larvae
Amphibalanus eburneus
When we think of barnacles, we think of the hard, white crustaceans that grow on the side of boats and docks. However, barnacles go through a variety life stages and metamorphosis before they spend their life on a hard surface. The image above is a barnacle larvae when it is in the cypris stage, think of it as a baby barnacle. This larvae is an example of zooplankton and spends a short period of time floating around in the water column. The second image summarizes the life cycle of a barnacle.

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.

Gulper Eel
Saccopharynx sp.
The Gulper Eel is known for its massive jaws, which are capable of swallowing prey whole. It’s stomach is also able to expand twice its size. It is found only in the deep see about 2000 to 3000 meters in depth.

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.

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.
