whitemargin stargazer

Whitemargin Stargazer

Also known as Marbled Stargazer, Popeye Fish, Pop-eyed Fish, Tube-nosed Stargazer. Found singly buried in the sand with just the mouth and eyes showing, wiggling its lure to attract its prey over coastal reef flats. The name stargazer comes from the fact the eyes are positioned on top of their heads! They are usually found buried in the sand with just their heads showing waiting to ambush their unsuspecting prey as they swim passed! Stargazer possess electric organs located in a specialized pouch behind the eyes and can discharge up to 50 volts, depending on the temperature of the water at the time!

mantis shrimp

Peacock Mantis Shrimp

Found in the Indian and tropical western Pacific oceans, the peacock mantis shrimp is a candy-colored crustacean known for its ability to quickly "punch" prey with its front two appendages. According to Oceana, the international ocean preservation advocacy group, this shrimp's punch is one of the fastest movements in the animal kingdom—so much so, that it's strong enough to break an aquarium's glass wall. But no worries: They mostly only use their fists of steel to break open mollusks and dismember crabs.

Pink See-Through Fantasia

Pink See-Through Fantasia

Its name makes it sound like a piece ofsexy lingerie but don't be fooled: the pink see-through fantasia is a sea cucumber, found about 1.5 miles deep into the Celebes Sea in the western Pacific, east of Borneo. It was only discovered a little over a decade ago, back in 2007, but the curious sea cucumber has a survival tactic that points to its longtime evolution: bioluminescence to ward off predators. The pink see-through fantasia is named for its transparent skin.

spotted frogfish

Frogfish

It's so easy to miss the frogfish, because these types of anglerfish (there are over 50 species of them) are nearly identical to their surroundings—mostly coral reefs. They resemble sponges or algae-covered rocks and come in pretty much every color and texture imaginable. Some frogfish even use their camouflage not to hide, but rather, to mimic poison sea slugs. No matter their appearance, one thing all species of frogfish have in common is their strange mode of locomotion. Although they can swim, most walk along their pectoral fins, which have evolved into arm-like limbs, including a joint that resembles an elbow.

Japanese Spider Crab

Japanese Spider Crab

They have the greatest leg span of any invertebrate animal, boasting a spine-tingling length of up to 5.5 metres from claw to claw, and can weigh up to 19kg. Spider crabs can survive with up to three legs missing, and are able to grow back their missing limbs during successive.

Ribbon Eel

Ribbon Eel

Usually seen nestled into burrows around coral reefs, the ribbon eel (sometimes called the leaf-nosed moray eel) lives in Indonesian waters from East Africa, to southern Japan, Australia, and French Polynesia. The juveniles start out black, with a pale yellow strip along the fins, and as they grow, transitions to a bright blue and yellow coloring. These eels are considered "protrandic hermaphrodites,"meaning they change sex from male to female several times throughout their lives.

The frilled shark

Frilled Shark

The frilled shark, Chlamydoselachus anguineus, is one of the gnarliest looking creatures in the sea. If it looks like an ancient beast, that's because it is: the prehistoric creature's roots go back 80 million years. The frilled shark can grow to about seven feet long and is named for the frilly appearance of its gills. Although shark in name, these animals swim in a distinctly serpentine fashion, much like an eel. They mostly feed on squid, usually swallowing their prey whole.

Deep Sea Dragonfish

Deep Sea Dragonfish

Deep down in the Atlantic Ocean, at depths of up to 5,000 metres, lurks this ferocious predator. The conditions down here are extreme – there's no light, no plant life, and the environment is entirely still because it is unaffected by storms or ocean currents. To deal with this, the dragonfish uses light-producing organs called photophores to lure prey into its fang-toothed jaws.

blue christmas tree worm

Christmas Tree Worm

Scientists found this strange creature at the Great Barrier Reef's Lizard Island and named it, aptly, the Christmas tree worm. The spiral "branches" are actually the worm's breathing and feeding apparatuses, while the worm itself lives in a tube. These tree-like crowns are covered in hair-like appendages called radioles. These are used for breathing and catching prey, but they can be withdrawn if the Christmas tree worm feels threatened.

Box Crab

Box Crab

Like so many other sea creatures, the box crab is a master of disguise. In this case, the crustacean—which mostly keeps to the seabed—buries itself beneath the sand, with just its eyes protruding from the mucky depths. One of the most fascinating aspects of the box crab's life cycle is its mating habits, which literally redefine what it means to be swept off your feet. When the male box crab has found its mate, it grasps onto her with its claws and carries her around the sea floor until she molts her shell.

squidworm

The Squidworm

Researchers with the Census of Marine Zooplankton first discovered the squidworm in 2007 during a cruise in a remotely operated vehicle some 1.8 miles underwater. The funky-looking fish is named for the 10 appendages protruding from its head, which look like tentacles. The squidworm uses these to collect debris falling from the open waters above, known as "marine snow."

Atlantic Wolffish

Atlantic Wolffish

Armed with four to six fang-like teeth on its jaws, there are a further three rows of crushing teeth behind that. And if that's not enough to make you squeamish, the Wolffish's throat is scattered with serrated teeth too. The Wolffish has a long eel-like body which can reach lengths upwards of 1.5 metres.

Fangtooth Fish

Fangtooth Fish

This menacing creature is one of the deepest-living fish ever discovered. It has been recorded as far down as 5,000 metres below sea level, where the pressure is 500 times greater than that of land. The fangtooth holds another title to its name: the largest teeth of any marine species, relative to the size of its body. In fact they're so disproportionally large that the fangtooth is unable to fully close its mouth.

Giant Isopod

Giant Isopod

These guys are native to chilly, deep waters and can grow to be quite large; in 2010, a remotely operated underwater vehicle discovered a giant isopod measuring 2.5 feet. These crustaceans, which sort of resemble a massive woodworm, are carnivores and usually feed on dead animals that fall down from the ocean's surface. Despite their discovery back in 1879, these creatures mostly remain a mystery. However, it's believed that giant isopods grow so large in order to withstand the pressure at the bottom of the sea.

Pacific Viperfish

Pacific Viperfish

This deep sea dweller is the ultimate predator. Using photophores located across its dorsal spine, the Viperfish lures unwilling prey before capturing them in its long, needle-like fangs. Definitely not a creature you should be messing around with. Similar to the Fangtooth, the Viperfish's large fangs are unable to fit inside their mouth, instead they curl back on the outside, resulting in an even more monstrous appearance.

Neon Slug

Nudibranch

With over 3,000 different species on record, the nudibranch is an extremely versatile kind of sea slug. These little guys are found pretty much everywhere, in both shallow and deep waters, from the North and South poles and into the tropics. There are two distinct kinds: dorid nudibranchs, which are smooth with feather-like gills on their back to help them breathe; and aeolid nudibranchs, which breath through a different kind of organ, also located on their backs, called cerata. Because the tiny nudibranch lacks a shell, it instead protects itself with bright camouflage, meant as a warning signal. But perhaps their wildest adaptation of all is the ability to quite literally swallow, digest, and reuse stinging cells from prey.

Sea Spider

Sea Spider

There are over 1,300 known species of sea spiders lurking both in the shallows and in waters as deep as 7,000 metres and if that doesn't make you squeamish, their leg span can range from a tiny one millimetre to over 25 centimetres. The Sea Spider's proboscis allows it to suck... out of its prey.

Spiny Red Crab

Spiny Red Crab

Prowling the ocean floor at depths up to 2,400 metres are these spiny red crabs. Their fast movements, clutching claws, and armoured body make it easy for them to catch, tear, and feast on fresh prey. This species is closely related to the hermit crab, with the shell being traded in for some gnarly spikes.

Sea Angel

Sea Angel

Although they're called sea angels, these creatures are actually predatory sea snails. This particular specimen, Platybrachium antarcticum, "flies through the deep Antarctic waters hunting the shelled pteropods (another type of snail) on which it feeds," according to the Marine Census of Life. Sea angels have special parapodia, or lateral extensions of the foot, that help to propel them through the water.

Gulper Eel

Gulper Eel

The gulper eel (also referred to as the pelican eel) is named for its massive mouth and jaw, which helps them to swallow prey whole. They can grow up to six feet in length and their huge mouths allow them to hunt down meals that are larger than them. This usually happens when food is scarce—it's believed that gulper eels usually eat crustaceans and other small marine animals.

Chimaera

Chimaera

This elusive ocean floor dweller is commonly referred to as a Ghost Shark. Little is known about these Chimaeras, which were only filmed recently in their natural habitat for the first time. The odd, stitch-like lines you see on chimaeras are actually sensory organs that detect movements and vibrations in the water.

marrus orthocanna physonect siphonophore

Marrus Orthocanna

Like a multi-stage rocket, this bizarre microscopic creature, Marrus orthocanna is made up of multiple repeated units, including tentacles and multiple stomachs. Technically, they are physonect siphonophores, which are related to the Portugese man o'war. Like ants, a colony made up of many individuals has attributes resembling a single organism.

The Black Swallower

The Black Swallower

Even hearing the name of this deep-sea monster would be enough to give anyone the chills. Although it's a slender-looking beast, the black swallower has an expansive, expandable stomach that is capable of swallowing prey over twice its size and 10 times its mass. Sometimes the black swallower bites off more than it can chew, meaning that its meal may begin decomposing in its stomach before it can be digested. The resulting gases released by the decomposing body forces the black swallower to the surface, where it cannot survive.

munnopis isopod

Munnopis Isopod

A virus? An alien? Nope. It's a Munnopsis isopod crustacean, and even scientists haven't figured out more than that about this deep Southern Ocean denizen, yet. Isopods are ancient creatures (they've been on Earth, in one form or another, for 300 million years or so) with no backbones that have seven pairs of legs. On land, you might be familiar with their cousin, the pill bug.

Barreleye

Barreleye

The ocean is home to some of the most bizarre creatures on our planet. Here’s yet another another example of a creature that makes you scratch your head about just how complex and advanced mother nature can be. The deep sea Barreleye fish looks like a glass domed submarine with the front top part of its head transparent, showing off its unique eyes.

Monkfish

Monkfish

Monkfish are voracious feeders, gobbling up whatever prey happens to be available. They eat shellfish, seabirds, diving ducks, fish and even other monkfish. Females live at least 13 years and males seven years. They grow to three to 4.5 feet long. Adult Monkfish live on the seafloor, typically on sand, mud and shell habitats. They often partially bury themselves in sediment to disguise themselves in order to ambush prey.

Red-lipped Batfish

Red-lipped Batfish

This bizarre-looking fish is also known as the Galapagos batfish and can be found at the bottom of the ocean. It's named for its red lips, which make it appear to be wearing lipstick. Although the red-lipped batfish appears to have legs, its limb-like appendages are actually fins, which the creature uses to stand on and to check out its surroundings.

Armoured Snail

Armoured Snail

There's no other snail in the world armored like the Crysomallon squamiferum, which lives over hydrothermal vents deep in the Indian Ocean. It goes by quite a few other names, including the "scaly-foot gastropod," "scaly-foot snail," and even the "sea pangolin." Today, its multilayered shell structure is inspiring stronger materials, from airplane hulls to military equipment.

Bioluminescent Octopus

Bioluminescent Octopus

One of the few known octopods known to use bioluminescence (or glowing with its own light), the Stauroteuthis syrtensis octopus lives about one mile deep in the Gulf of Maine. It can position its photophores (light-emitting organs) to fool prey into swimming right into its mouth.

Flamingo Tongue Snail

Flamingo Tongue Snail

With a name like flamingo tongue snail, and the flamboyant coloration to match, you might think this Cyphoma gibbosum has a shell worthy of collecting. Not so. All of the flamingo tongue snail's color comes from the soft parts of its body, which envelop its shell. When threatened, it can retract its mantle flaps, exposing its true shell.

Sarcastic Fringehead

Sarcastic Fringehead

The Sarcastic Fringehead appears relatively harmless when it isn't provoked and actually possesses no threat to humans whatsoever. However, when this footlong fish is agitated, it will open its massive mouth in an attempt to fend off predators. It's that defense tactic that is both surprising and frightening.

Vampire Squid

Vampire Squid

Strangely enough, this form of sea life is neither a squid, nor an octopus, despite its appearance. Scientists have designated the vampire squid as a completely separate animal, even though it has eight arms and two tentacles. Again, the name can be confounding—these creatures don't suck blood and actually are pretty passive hunters, considering they're filter feeders. Instead, the name comes from the skin between its arms, which resembles a cape. Oh yeah, and this little dude lives in the pitch black waters of the mesopelagic zone.

cornfish

Coffinfish

Also known as "the sea toad," these deepwater fishes are relatives of the frogfish. These creatures have a small lure, protruding from a depression behind their eyes. Coffinfish use it to lure prey toward them, and because there is so little light at the depths where they live, it allows them to quickly attack. These fish also boast such sizable gills that they can increase their body volume by up to 30 percent upon inhaling a significant quantity of water, that would be the equivalent of a human inflating their lungs to become the size of their full abdomen—not exactly possible.

Leafy Seadragon

Leafy Seadragon

Found along the southwestern coast of Australia, the leafy seadragon, Phycodurus eques, uses its fins not only to propel itself through the water, but as camouflage to resemble a piece of drifting seaweed. Because they have pretty big heads compared to the rest of their body, leafy seadragons are able to concentrate pressure at their mouth to suck in prey. Similar to seahorses and pipefishes, the males carry around fertilized eggs. But without a special pouch, the leafy seadragon carries the eggs beneath its tail.

Stareater

Stareater

Recently found in the waters between Australia and New Zealand this is an aggressive-looking fish. Like many other deep sea predators, it has a bioluminescent red chin barbel that is used as a lure to attract small prey. An alternative name for the Stareater is Snaggletooth, which most likely refers to its sharp, needle-like teeth it uses to catch prey.

Blob Fish

Blobfish (aka Fathead)

Scientists call this fish Psychrolutes microporos, but also, more directly, "Fathead." Smithsonian Magazine even notes that the weird looking creature is largely considered the "World's Ugliest Animal." The blobfish is a pretty incredible sea dweller, surviving at depths in excess of 4,000 feet, where the pressure is 120 times higher than at the surface. And here's the thing: the blobfish is only actually ugly when it's brought up to the surface. Most fish have a swim bladder, or a sac of air inside its body to keep buoyant. When fish are removed from their typical environments, these sacs swell up, leading to the innards pushing out through the mouth. Technically, we only think of the blobfish as ugly when it's dead—so maybe think twice before pointing and laughing.

Crossota Norvegica Jellyfish

Crossota Norvegica Jellyfish

Known for its vibrant red coloring, the Crossota norvegica is a kind a jellyfish, collected from the deep Arctic Canada Basin. It lives about 2,500 meters beneath the surface, and uses ectodermal cells with nematocysts to sting prey. It's not exactly clear what these creatures feed on, but it's most likely a combination of zooplankton and phytoplankton.

Kiwa Crab

Yeti Crab

This furry-clawed crab looks so unusual that when scientists discovered it 5,000 feet deep on a hydrothermal vent south of Easter Island, they designated it not only a new genus, Kiwa, but a new family, Kiwidae—both named for the mythological Polynesian goddess of shellfish. It's likely blind and may use bacteria in its furry claws to detoxify its food.

Yellowhead Jawfish

Jawfish

Let's state the obvious: this thing looks like it's throwing up, what you're actually seeing is the strange mating process of the jawfish, a species native to coral reefs in the Caribbean Sea and western Atlantic. Beyond using their jaws to scoop up sand, the males also use their huge mouths to carry eggs until they hatch. Still, other times, their mouths are like weapons, used in jousting matches—the jawfish truly puts its money where its mouth is.

Vigtorniella Worm

Vigtorniella Worm

What do you get when a whale dies at sea? You get a feast if you're a polychaete worm like this newly discovered Vigtorniella, found a about a half mile below sea level in Sagami Bay, Japan.

Goblin Shark

Goblin Shark

Long story short: Goblin sharks look scary as hell. The super-rare creature can grow up to 15 feet in length and has the ability to thrust its whole jaw outward in order to capture prey. Fewer than 50 goblin sharks have been spotted since 1898, so if you're hoping to see one, chances are slim.

Terrible Claw Lobster

Terrible Claw Lobster

Named Dinochelus ausubeli for its "terrible or fearful" (dinos in Greek) claws (chela). T his new species of blind lobster joins a very small list of cousins in the genus Thaumastochelopsis. Only four other individuals, in two species, had been found previously, both in Australia. Scientists collected the specimen during the Aurora mission in 2007, led by the U.S. and French natural history museums, and the Philippines Bureau of Fisheries and Aquatic Resources. That second part of its name, ausubeli is also significant: It's in honor of Jesse Ausubel, a co-founder of the Census of Marine Life.

Pycnogonid Sea Spider

Pycnogonid Sea Spider

Found in the Antarctic, this male pycnogonid spider (or a distant relative of a spider, anyway) bears its own eggs. It has virtually no abdomen, yet has a leg span of about 25 centimeters, which means it's about on par, size-wise, with some of the largest spiders on land, like the Goliath Bird-Eating tarantula of South America.

Anglerfish

Anglerfish

Just like in Finding Nemo, the deep sea varieties of Anglerfish have nightmarish mouths filled with long, fanged teeth. Their characteristic mode of predation is by using a fleshy growth from their head as a fishing lure, waving it back and forth to attract pray. The jaws and bodies of Anglerfish are highly expandable, meaning they're able to swallow prey up to twice their own size.
