Jewel Squid

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.

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.

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.

Psychedelic Medusa 

Crossota millsae

The Psychedelic Medusa is a deep-sea hydrozoan that is abundant in the North Pacific. The mini-jelly is found at depths between 1000m to 3800m, and are often observed drifting near the ocean floor. It also has an eccentric reproduction behavior uncommon in cnidarians. The females display viviparity, and carry the babies in her bell until they are ready to hatch.

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.

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.

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.

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.

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.

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.
