1. Coelacanth
   Goblin Shark
2. Dragonfish
   Dumbo Octopus

The Goblin Shark is considered to be the only member of an incredibly ancient line of sharks that dates back 125 million years. Not only are they weird to look at but they're also bizarre to watch when they eat as well. Their jaw actually extends out and grasps at food like a hand snatching it from the water.

1. Terrible-Claw Lobster
   Spiny Red Crab
2. Frilled Shark
   Giant Isopod

Giant isopods can grow to a size of around 19 inches in length. They aren't fished in many places although they have found their way onto menus in some Asian countries. They're also kept as pets by some people so keep that in mind if you ever want a monster bug in your house.

1. Frilled Shark
   Viperfish
2. Stargazer
   Grenadier

The frilled shark looks like a leftover from prehistoric times and can be found anywhere from 120 meters down to about 1500 meters below the surface. Their nasty, little razor-sharp teeth are trident-shaped and backward-facing to ensure that if the shark bites something it won't get away.

1. The Black Swallower
   Amphipod
2. Blue-Ringed Octopus
   Vampire Squid

You'll find the vampire squid at around 900 meters below the surface. Despite the name, they don't seem to do much bloodsucking; it's mostly the blood-red color that lends itself to the moniker as well as the hood-like web of flesh that links their tentacles.

1. Gulper Eel
   Hatchetfish
2. Anglerfish
   Wolffish

The little bobber on the top of an anglerfish's head is a modified dorsal fin. Not all anglerfish produce light with it but some do have a bioluminescent organ that is used to attract prey like bait on a fishing pole. That's how they got the name "anglers."

1. Giant Tube Worm
   Big Red Jellyfish
2. Megamouth
   Firefly Squid

The Big Red Jellyfish may not have the most clever name but it is accurate. It was discovered in 2003 and grows to a size of around 30 inches which, for a jellyfish, certainly is big. Unlike some jellies, its tentacles aren't for stinging but for grabbing food and pulling it in.

1. Giant Squid
   Lancet Fish
2. Megamouth
   Dumbo Octopus

Giant Squid can grow to over 40 feet in length, making them one of the largest creatures on Earth. Photos of the squid didn't even exist until 2004, and it would be another eight years before one was caught on video. They're thought to prey on whales, and their tentacles are outfitted with some wicked spikes to dig into flesh.

1. Giant Tube Worm
   Pacific Blackdragon
2. Gulper Eel
   Megamouth Shark

The Gulper Eel gets its name from its impressive mouth which looks like some kind of old-timey steam shovel. Thanks to the size of its jaws it's actually able to eat fish that are larger than itself.

1. Oarfish
   Barreleye
2. Firefly Squid
   Fanfin Seadevil

The oarfish effectively looks like a giant, living ribbon. There's a belief that oafish may be the source of stories about sea serpents, owing to the fact that they do beach themselves after storms sometimes, and, if they are ill, they will rise to the surface. A 30-foot-long snakelike fish might trick people into thinking it's a monster.

1. Stargazer
   Chimaera
2. Blobfish
   Wolffish

Down between 600 meters and 1,200 meters where a blobfish lives comfortably it looks a lot like a regular fish. Unfortunately they do incredibly poorly with changes in pressure since its gelatinous flesh is only slightly more dense than water.

1. UFO Jellyfish
   Snaggletooth
2. Snipe Eel
   Coffinfish

The Coffinfish is capable of puffing itself up when threatened and is a member of the same species as the anglerfish though it obviously lacks the fun little dangler hanging in front of its face.

1. Viperfish
   Hagfish
2. Atlantic Wolf Fish
   Lanternfish

Living at depths down to 500 meters, the wolf fish is notable for its jaw full of crooked, mismatched looking teeth. It actually has a number of cone-shaped teeth in its mouth as well as molars for crushing and teeth down its throat as well.

1. Black Swallower
   Chimaera
2. Grenadier
   Sea Spider

The Chimaera is named for a mythological beast that was a mishmash of other creatures. It's also known as a rabbitfish, a ratfish and the much cooler name ghost shark. In a weird twist of biology, males have retractable sexual appendages in their foreheads.

1. Japanese Spider Crab
   Terrible-Claw Lobster
2. Sea Pig
   Coelacanth

The sea pig or scotoplane can be found at depths down to 5,000 meters. They're not exactly what you'd call gourmets since they survive by extracting organic particles out of the mud beneath them.

1. Spiny Red Crab
   Giant Isopod
2. Sea Spider
   Hagfish

The Spiny Red Crab is also called the King Crab and it's one of the most fished crabs in the world. Down on the ocean floor, they eat smaller crabs or starfish but if times are tough they'll scavenge dead animals on the ocean's floor as well.

1. Fanfin Seadevil
   Snaggletooth
2. Pacific Blackdragon
   Hatchetfish

The Pacific Blackdragon is a long, eel-like fish found at depths as low as 1,000 meters. The fish is almost all black to help it hide from the prey that it ambushes but it also has a little light on its chin to lure in unsuspecting prey. You'd figure anything that deep would know to avoid lights by now.

1. Dragonfish
   Black Swallower
2. Snipe Eel
   Giant Tube Worm

Giant tube worms are one of the strangest life forms on Earth. They can live in the harshest parts of the ocean, next to vents that release heavy amounts of toxic hydrogen sulfide into the water They feed through a process called chemosynthesis where the bacteria that fill them produce all the nutrients they need to survive.

1. Snipe Eel
   Oarfish
2. Gulper Eel
   Lancet Fish

The snipe eel can occupy a crazy range of depth from 300 meters down to as deep as 4,000 meters. They are incredibly long and whip-like and though they can be around 6 feet long they may weigh only a pound at the same time.

1. Firefly Squid
   Barreleye
2. Hagfish
   Coffinfish

The hagfish is just really unappealing to look at and, apparently, to handle. When defending itself the hagfish releases mucous from numerous glands that, when mixed with the water around it, will produce up to 20 liters of thick, suffocating slime.

1. Fanfish Seadevil
   Amphipod
2. UFO Jellyfish
   Megamouth Shark

The Fanfish Seadevil has a vast array of thin filaments that branch off of its body like hairs. These filaments are bioluminescent to attract prey to those massive jaws. Every one of these monsters you see in pictures is female as the males are remarkably tiny and have to bite into the female's underside and latch on to breed.

1. Grenadier
   wolffish
2. Lanternfish
   Viperfish

Lanternfish may not look all that remarkable but these little guys are rather surprising. Aside from their ability to produce light, hence their name, they also make up the bulk of all deep-sea biomass with some estimates saying that 65% of all deep-sea life is just lanternfish.

1. Hatchetfish
   Anglerfish
2. Blobfish
   Snaggletooth

The hatchetfish gets its name from the body shape which resembles the head of a hatchet. There are freshwater versions of the fish that exist in much shallower water while the deep sea versions can be found down to 1,500 meters

1. Fangtooth
   UFO Jellyfish
2. Coelacanth
   Lancetfish

Lancetfish are considered a bit of a nuisance animal and get caught up in commercial fishing for things like tuna. You can actually eat lancetfish and they're described as being sweet but there isn't really an industry for them.

1. Wolffish
   Fangtooth
2. Dragonfish
   Vampire Squid

The fangtooth is more mouth than anything else, which is oddly common for deep-sea fish. These are some of the deepest dwelling fish n the world and can be found all the way down to about 5,000 meters which is about 3 miles down.

1. Dumbo Octopus
   Vampire Squid
2. Blue-Ringed Octopus
   Nautilus

This incredible creature has been recorded at depths of 7,000 meters which is inhospitable to almost every other life form in the ocean and is the deepest any octopus has ever been recorded at. They're usually about a foot long though some have been recorded at upwards of 5 feet.

1. Black Swallower
   Firefly Squid
2. UFO Jellyfish
   Snipe Eel

The UFO jellyfish was filmed in the Mariana trench by researchers at the National Oceanic and Atmospheric Administration. UFO Jellyfish is actually just a colloquial description as the jellyfish was never officially named.

1. Viperfish
   Lanternfish
2. Goblin Shark
   Snaggletooth

The snaggletooth fish is another in a long line of creatures that seems to have more teeth than anything else. It also sports a tiny chin barbel that produces light to lure in prey.

1. Hagfish
   Barreleye
2. Wolffish
   Oarfish

The barreleye is definitely one of the most unusual fish in the sea. Their name comes from the fact that their eyes are actually shaped like tubes or barrels and point straight up.

1. Ghost Shark
   Marlin
2. Hatchetfish
   Grenadier

Grenadier fish are extremely common fish in the deeps probably due to the fact they reproduce like it's going out of style. A grenadier may lay up to 100,000 eggs at a time which is pretty remarkable.

1. Megamouth Shark
   Deepstaria
2. Nautilus
   Vampire Squid

Deepstaria Reticulum doesn't sound like an impressive name but this giant squid exists at a depth of around 5,000 meters. The bell portion of a jellyfish which is usually small and rounded is the massive, sheet-like portion of this jelly.

1. Vampire Squid
   Colossal Squid
2. Firefly Squid
   Sofa Shark

Sofa sharks can be found at depths of 1,400 meters. They have broad heads and round snouts along with very short dorsal fins unlike what you might expect from a shark. Essentially yeah, they do look like a sofa that can swim.

1. Giant Tube Worm
   Squidworm
2. Black Swallower
   Snipe Eel

The Squidworm was found 2,800 meters below the surface and has 10 long appendages or tentacles on its head that are each longer than its actual body. It uses these appendages like fingers to pluck little bits of food out of the water for itself.

1. Japanese Spider Crab
   Terrible-Claw Lobster
2. Yeti Crab
   Spiny Red Crab

The Yeti Crab got its nickname thanks to the weird hair all over its long arms which made researchers think of the mythical yeti or abominable snowman. Aside from the unusual hair the crab also is thought to be completely blind since it doesn't seem to have any functioning eyes.

1. Megamouth Shark
   Ghost Shark
2. Gulper Eel
   Fangtooth

The megamouth shark can grow to lengths of around 18 feet and are rarely seen by humans. They eat by opening the massive mouth that gave them the name and lazily swimming along, pulling in plankton just like whales do.

1. Anglerfish
   Viperfish
2. Devil Ray
   Snaggletooth

The viperfish is one of the most famous deep sea creatures thanks to its stunning appearance. It looks like the skeleton of a fish from Hell complete with needle-like fish and a lower jaw on a hinge that lets it open incredibly wide to bite down on prey.

1. Dragonfish
   Red Pufferfish
2. Black Swallower
   Frilled Shark

The massive pouch hanging below a black swallower is actually the fish's stomach. It's so large and able t expand to such a great size that the swallower can eat a fish twice its length and 10 times its mass. That's essentially the same as a human eating a car.

1. Coelacanth
   Rockfish
2. Spiny Sea Dog
   Lurching Tusk Fish

The Coelacanth was believed to have gone extinct literally millions of years ago and was only known through fossil records. In 1938 a living coelacanth was caught and now it's known there are a couple of species of the fish still living, even though they're extremely rare.

1. Sea Skitterer
   Spindle Crab
2. Sea Spider
   Yeti Crab

Sea Spiders are not true spiders but that probably doesn't matter if you have a fear of spiders or other multi-legged creatures. Their leg span can reach over two feet and when it comes time to eat, they stick their proboscis into prey to suck out the nutrients.

1. Firefly Squid
   Vampire Squid
2. Nautilus
   Clownfish

The firefly squid is one of the most incredible looking creatures in the world. While it normally looks like an average squid it can also activate photophores across its body to produce a remarkable pattern of blue lights.
