The transparent cockatoo squid, also known as the glass squid, lives in the deep dark depths of our oceans. It has adapted in many ways to help it survive down there, including: retaining ammonia to give its balloon-like body and to help it float, its bug eyes to help it take in all that darkness and polka dot spots to serve as camouflage.

Cars, Trucks and Motorbikes

Yes! There's basically a highway down there beneath the waves. A treasure trove of vehicles lies beneath the sea after a cargo ship sunk in 1941 after being bombed by two German places - these vehicles have now been at the bottom of the ocean for a whooping 73 years!

Ribbon Eels

Ribbon eels are one of the most amazing creatures that only divers can see. They are mostly found on healthy coral reefs and are identified by popping their heads out of hiding - its very rare to see one swimming freely, displaying its ribbon effect body - so, you best have a beady eye if you want to try catch sight of one!

Ancient treasures

Crossings of the sea were recorded to have taken place anywhere between 60,000-70,000 years ago! That's a lot of years for hidden treasures to find themselves on the ocean floor. The trouble is, all those years and ocean movements will have buried the treasures under layers of sea, sand and wildlife - good luck finding anything unless you're a trained diver!

Goblin Sharks

Goblin sharks are species of fish that live in the depths of the ocean - they are rarely seen but are believed to live alone. What's impressive about them is that they can actually extend their jaw three inches out of its mouth! An ideal party trick to have when you need to catch fish to survive.

In the oceans shadows lies a fish with a transparent head! Yes, you read that right! A head that is totally and completely see-through meaning they can actually look up to see if any predators are lurking. Their head has a green tinge which acts as sunglasses, allowing them to spot most prey (which have glowing underbellies).

Ancient sculptures

Deep in the ocean you can find statues riddled with coral reef and fish making their crevices their home. These statues came about through natural disaster sinking cities but also thanks to famous artists designing and creating them and then plonking them in the sea!

Blob Fish

The Blob fish has been known to be the ugliest creature on Earth. However, the Blob fish actually only look like a miserable pink lump when it has been dragged from its habitat to the surface of the water and this is down to it being in uncomfortable surroundings. When its at home, at the bottom of the sea, the Blob fish actually just looks like any other fish!

Roman cities

The ancient resort of Baiae, in the gulf of Pzzuoli was said to the the party town of the Roman era. However after volcanic activity which caused the earth to rise and fall, the city sunk about 4-6 metres under water.

Transparent Sea Cucumber

Sea pig are one of the oceans creatures that you'll never likely see if your lifetime. As the name suggests, they are similar to the land 'pig', except they have many more legs and no eyes!

The piglet squid really does look like that! I know, it's like something out of a cartoon! This little ocean dweller is found in the Pacific and Atlantic oceans. They unfortunately don't live for very long and once the mating has happened and the eggs laid, both male and female piglet squids die.

We all hear about the plastic pollution initiative about plastic entering our waters, but we rarely hear about how much of it is actually already sat at the bottom of our oceans. Amongst some of the most incredible species in the world, lies 14m tonnes of micro plastics, meaning there could be 30 times more plastic at the bottom of the ocean than we see floating at the surface.

A Fangtooth

The Fangtooth, otherwise known as the 'Ogre fish' is a bony fish that lies at tremendous depths of our oceans - they are the deepest living fish! Scientist known more about the young fish than the mature as the older they get, the further they descend to the bottom of the ocean so therefore are hard to find and to study.

Yes, that's right! Mermaids live in our oceans! Well, kind of. Mermaids are mythical creatures that have been in stories for decades and some people have even claimed seeing real-life mermaids swimming in our oceans. However, there is very little, to no evidence that mermaids actually exist, despite some stories being extremely believable.

This long-armed creature is known as the Big Fin squid - a mystery squid! and the 'daddy long legs' of the ocean world. The long, tentacles are used like a spider web to help the squid catch it prey, however seeing this in action is hard to come by as they are extremely rare to see!

These sea gooseberries really do look like little tasty delicacies bobbing around the ocean and eventually ending up on our beaches. Would you believe that these little jelly-like balls are actually incredible predators? Eating up to 10 times their bodyweight in one day! And they even like to munch on each other!

Bioluminescent Deep Sea Creatures

Many of the oceans creatures are in fact glowing! Yes, actually glowing. Like a beautiful light display hidden away for only night divers to see. Bioluminescent creatures produce their own light through a series of chemical reactions and many creatures rely on this to find prey, camouflage and to communicate.

Vampire Squid

Unlike the name suggests, Vampire squid don't actually like to feed on blood - disappointing, I know! It can turn itself inside out to avoid predators and if feeling threatened, it will glow to distract those attacking it. A cool fact is that it can regrow its limbs should an accident occur!

Fluorescent Coral

Deep beneath the surface of the sea, you can find an abundance of rainbow coral. Corals get their glow from a variety of pigments that actually act as a sunblock to their sensitive surfaces. The reason we can see the coral so brightly the deeper it is, is that the light of the corals is not polluted by sunlight - just like seeing the stars away from street light pollution.

More ocean!

Image source: universal-sci.com
One of the greatest things about the ocean is that there is still so much of it yet to be discovered: it might be shocking to read that scientists have only discovered around 5% of the ocean! The rest, especially the depths, are yet to be explored and could contain some of our worlds greatest secrets.

A cafe

Yes, a cafe! Not quite the place to get your morning cappuccino, but a place to watch sharks feed. Once a year, around 20% of the Great White shark population descend from the Californian waters to those of Hawaii. However some do not make the trip and instead stop off at the 'White shark cafe': a spot in the middle of the Pacific where they go to randomly feed!
