Fangtooth

Anoplogaster cornuta

The Fangtooth is a ferocious predator that is found at depths between 600 m to 5000 m. It has large, needle like teeth that are used to catch prey. It also has extremely sensitive sensory canals underneath of its scales used to detect movement in the water. Furthermore, their preferred prey are crustaceans and fish.

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.

Black-devil anglerfish

Melanoncetus johnsoni

The Black-devil anglerfish is a skilled predator that lurks in the darkness. It uses a bioluminescent organ, a top its head, to lure unsuspecting prey into its jaws. Even though these fish are terrifying to look at, they are about the size of a grape fruit. To save energy, they remain immobile in the water, yet they can detect even the slightest vibrations. Since finding a mate is hard at this depth, male fish will attach themselves to a female and slowly dissolve into her tissue; so she is able to use the sperm the male provides at any time. In addition, this is the fish that tried to eat Marlin and Dory in “Finding Nemo.”

Googly-eyed glass squid

Teuthowenia pellucida

The Googly eyed squid is a rare oddity that is found in the southern hemisphere. It has a large, spherical head that is filled with water and teeny, tiny tentacles that help propel it through the water. If it comes across a predator, it deflates its head and draws its tentacles into its cavity. On the other hand, it may also fill the cavity with water to increase its size, and intimidate the predator. If all fails, it will ink and try to escape through the darkness. Furthermore, baby squids can be found at the surface (0-600m); then slowly migrate downwards as they mature into adults (1600-2500m).

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.

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.

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.

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!

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.

Blacksnout Seasnail

Paralipparis copei copei

The Blacksnout Seasnail may not look like a snail, but it does have a slimy, gelatinous substance that covers its body. It can be found at depths between 200 m to 1692 m, and adults grow up to be 17 cm in size (approximately 6.5 in). It also has an elongated body that resembles an eel. Furthermore, it can be seen rolling itself in a loop; this behavior is a defensive posture that makes it appear like a jelly. In the darkness, predators tend to avoid the Blacksnout Seasnail because its often mistaken as a hunter due to its appearance and behavior.

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)

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.)

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.

Sea Angel

Cliopsis krohni

The Sea Angel is a tiny snail that is only 4 cm in length and found at depths as deep as 1500 m. Even though it is small, it is a viscous predator. It hunts other midwater snails using a structure called a radula. Unlike other snails, the Sea Angel’s mouth is located on top of its head. It also uses swimming “wings” to propel through the water.

Spookfish

Winteria telescopa

The Spookfish’s eyes act as a telescope and are designed to maximize light in the deep ocean. Its eyes contain rod cells that help distinguish between ambient light and bioluminescent light. This adaptation helps avoid predators and catch prey.

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.

Alexander Semenov Continues to Photograph the Earth’s Most Fragile Marine Wildlife Near the Arctic Circle

Is it bad that I just... I just wanna be some sort of mermaid that can go from the shallows to the deepest parts of the unexplored ocean? Like, I've looked at pictures of the ocean where you can't see the bottom and I just... I just really wanna be some sort of mermaid and go wherever I want.
