It has been suggested that we know more about deep space than we know about the deep oceans. After all, we know that there is no such thing as a giant squid: they are only the stuff of Medieval seafaring lore, right? Not quite. The giant squid is real, and while they may not pose an imminent danger to ships on the ocean sea, they can exceed lengths of 30 feet.<\/span><\/p>\n

However, there are plenty of other marine oddities, about which we know very little. Some are living fossils that have changed very little since prehistoric times; studying them can give scientists clues about earth’s distant past. Others are extremely rare, such as the shark that has been seen less than 50 times in over a century. Keep reading to learn more about strange sea creatures you’ll probably never see in real life, like terrifying spider crabs, giant squids, octopus, and more.

The Armored Snail Thrives In Deep-Ocean Vents<\/span><\/h2>\n
Armored snails are the stuff of legends. These creatures live in deep-ocean vents<\/a>, which are extreme environments that receive high levels of heat and chemicals from underneath the ocean floor. And their multi-layered shells probably help protect them in this intense environment.<\/span><\/p>\n

What exactly is the shell made of? For starters, the composite material and structure are unlike anything that humans have contrived. Like other organisms that live in the deep-ocean vents, armored snails are tiny, usually measuring only about four millimeters or about 0.16 inches.<\/span><\/p>\n

Scientists discovered this oddity that lives in Australia’s Great Barrier Reef. Christmas tree enthusiasts may be dismayed to see that the Christmas tree worm’s<\/a> “branches” are blue and look more like a fake plastic Christmas tree. Nevertheless, the points at the end of each bristle look like they could be Christmas tree lights.<\/span><\/p>\n

The whole “tree” isn’t the worm; the worm itself lives inside the vertical tube that resembles the Christmas tree trunk. It can recoil its “branches” at will, probably as a defensive mechanism to protect itself from its enemies. <\/span><\/p>\n
$\"Giant$
*Giant isopods look like terrifying underwater Beatles. Photo Credit: Kikujungboy CC\/Shutterstock<\/em><\/figcaption><\/figure>\n*Giant Isopods Are Sea Vultures<\/span><\/h2>\n
There are about 20 different types of giant isopods, and they are called “giant” for a reason. These underwater creatures can grow to be up to 2.5 feet in length<\/a> – just imagine one running through your kitchen in the middle of the night! They probably grow so big as an evolutionary adaptation that allows them to withstand immense underwater pressure.<\/span><\/p>\n

Giant isopods help keep the oceans clean. They feed on dead marine life, usually when it falls from closer to the surface of the ocean, thereby helping to purify the water. In other words, they do in the ocean basically what vultures do on land.<\/span><\/p>\n

Sea cucumbers are oddities in and of themselves. Far from being a marine vegetable, as the name suggests, echinoderms belong to the same animal family as sea urchins and starfish. They live on the seafloor and feed in a way similar to earthworms, basically eating dirt and then pooping it out.<\/span><\/p>\n

Portuguese Man-Of-War is a special kind of creature that isn’t one kind of creature at all; it is a collection of several animals that function together<\/a> as if they are one animal. Marrus orthocanna is a microscopic, and less well-known, version of the same thing.<\/span><\/p>\n

Fans of SpongeBob may be at least a little bit tempted to call this funny-looking creature a Squidward, but it is a squid worm. Squid worms were only discovered in 2010, during explorations off of Indonesia. They live about 3000 feet underwater.<\/a><\/span><\/p>\n

This worm pretty much rises and falls with the ocean currents that pass through, feeding on algae and plankton.

*This squid looks like it is ready to suck your blood. Photo Credit: Flickr<\/em><\/figcaption><\/figure>\n*Vampire Squids Are Real<\/span><\/h2>\n
Forget the giant squids that Medieval sailors spun long yarns about centuries ago. The vampire squid, which lives off of Monterrey, California, takes the cake here. Its eyes are terrifying enough – they are red, though they can sometimes appear blue, giving the creature the otherworldly appearance of a vampire.<\/span><\/p>\n
$\"Vampire$
*Vampire squid. Photo Credit: Flickr<\/em><\/figcaption><\/figure>\n*But even more terrifying is the talon-like appendages on the tentacles, which aren’t sharp but certainly look terrifying.

Gulper eels are aptly named – you can see in the picture how big their mouths are relative to the rest of their bodies! Like other eels, they look like underwater snakes, with long, slender body that allows them to swim freely through the ocean.<\/span><\/p>\n
$\"Umbrella$
*Umbrella mouth gulper eel. Photo Credit: Wikipedia<\/em><\/figcaption><\/figure>\n*What sets these creatures apart is that their massive mouths<\/a> can swallow prey the size of an adult human.

In the time since, the fathead has been popularly voted as the ugliest animal in the world. While these creatures may be endangered, they often turn up in the fishing nets of trawlers in the waters off of New Zealand. Due at least partly to fathead’s ugly appearance, the fisherman sees little reason to throw the fish back into the water.<\/span><\/p>\n

When animals die, there are usually scavengers that eat up the carcass before it rots. On land, vultures perform this very necessary duty. And in the sea, especially in the waters around Japan, there are Vigtorniella worms<\/a> to clean up dead marine animals. Yes, there are many kinds of sea worms, and they are not all that different from their terrestrial relatives.<\/span><\/p>\n

On land, we think of slugs as basically snails that do not have a shell. But this underwater anomaly, the golden lace nudibranch, is a type of mollusk that has a shell early in life but then sheds it.

The Armored Snail Thrives In Deep-Ocean Vents<\/span><\/h2>\n
Armored snails are the stuff of legends. These creatures live in deep-ocean vents<\/a>, which are extreme environments that receive high levels of heat and chemicals from underneath the ocean floor. And their multi-layered shells probably help protect them in this intense environment.<\/span><\/p>\n

What exactly is the shell made of? For starters, the composite material and structure are unlike anything that humans have contrived. Like other organisms that live in the deep-ocean vents, armored snails are tiny, usually measuring only about four millimeters or about 0.16 inches.<\/span><\/p>\n

There are about 20 different types of giant isopods, and they are called “giant” for a reason. These underwater creatures can grow to be up to 2.5 feet in length<\/a> – just imagine one running through your kitchen in the middle of the night! They probably grow so big as an evolutionary adaptation that allows them to withstand immense underwater pressure.<\/span><\/p>\n

Giant isopods help keep the oceans clean. They feed on dead marine life, usually when it falls from closer to the surface of the ocean, thereby helping to purify the water. In other words, they do in the ocean basically what vultures do on land.<\/span><\/p>\n
