Pink Helmet

Aglantha digitale

The Pink Helmet is a mini hydromedusa that comes in a variety of vibrant colors. The tiny jelly is only 4 cm in size and is found towards the surface of the ocean. The purple and blue hues we see in its bell are caused by a phenomenon known as iridescence, when light strikes the jelly’s thin tissue at different angles  (similar to what we see in a soap bubbles). It also has orange pigmentation near its mouth; this pigmentation helps attract prey and mask luminescence. Furthermore, females tend to be more colorful than males.

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.

Vampire Squid

Vampyroteuthis infernalis

Even though the Vampire Squid is named after a notorious monster, this gentle creature does not live up to its name. It is only a foot long and occupies depths between 650m to 1500m in the deep ocean. Unlike other squids, it has reduced musculature and collects particles in the water column. However, it is capable of huge bursts of speeds. It uses bioluminescence to confuse both predators.

Hula Skirt Siphonophore

Physophora hydrostatica

The Hula Skirt Siphonophore a deep sea siphonophore that is found between 700 m to 1000m. It is made of a colony of hundreds tiny zooids. The top portion of the colony holds the swimming bells, which allow the colony to move. The bottom of the siphonophore holds the orange ‘hula skirt,’ which is full of stinging tentacles.

Pigbutt worm

Chaetopterus pugaporcinus

The Pigbutt worm or the flying buttocks of the sea is spotted floating between 965 m to 1300 m in the deep ocean. It is actually a polychaete (polly-keet) worm species that burrows in the ground as an adult, and floats around the ocean as a baby. The worm feeds itself : by creating a balloon of mucus; collecting particles on the mucus; and then consuming the particles. It is the rarest and thickest worm in the deep ocean, for only ten have been spotted.

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.

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.

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.
