Black- Eyed Squid

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. 

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.

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.

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.

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)

Dear ocean enthusiast and supporters,

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!

Pyrocystis fusiformis is a common plankton that produces bioluminescence. Not exactly a marine animal, but an amazing organism that produces bioluminescence. So, I thought it was worth sharing on this page. 

Pyrocystis fusiformis

Pyrocystis Fusiformis is a marine dinoflagellate that is non-motile and has a short life cycle (5-7 days). When disturbed, the dinoflagellate displays vibrant, blue bioluminescence. The bioluminescence is design to startle grazers, or cause them to glow, making them more vulnerable to predators. During the day, it uses photosynthesis to produce its own food, and it produce bioluminescence at night. Furthermore, it fixes carbon from the ocean and produces oxygen for the marine animals that live there. All in all, I find this diamond shaped plankton to be unique and beautiful.

Jewel Squid

Histioteuthis heteropsis

The Jewel Squid is covered in color-changing photophores that resemble sparkling gem stones. They also have a light-red coloration and are about 20 cm in length. They display a unique behavioral adaptation called diel migration. During the day, they stay at depths around 400-1200 m, and then surface during night (0-400m). This behavioral pattern is designed maximize feeding at night, and avoid predators during the day. The primary predator of the Jewel Squid is the Sperm Whale.

An amazing glowing ctenophore!

Bloody-belly comb jelly

Lampocteis cruentiventer

The Bloody-belly is a 16 cm ctenophore that is found at depths 700 m to 1200m. It is crimson red in color and appears black in the deep ocean. However, the jelly has the ability to emit a different color. Furthermore, it uses highly iridescent ctenes to propel through the water.

Pacific Viperfish

Chauliodus macouni

The Pacific Viperfish looks intimidating with its sharp, pointy teeth and large jaws. However, its body is small and elongated. It can be found at depths ranging from 250m to 4390m. The Pacific Viperfish long teeth are an unique adaptation designed to keep prey trapped, but it is dangerously close to its eyes. There have been instances when they have caught prey that are too large to swallow and it dies along with its last meal. The Pacific Viper also has photophores along its body and a light organ near its dorsal fin. These organs exhibit bioluminescence and help with attracting pray: as well as, communicating with mates and confuse predators. It is one of the most ferocious predators of the deep ocean.
