1. Red Spiny Crab
This brightly-colored crustacean sports an impressive suit of spiky armor, which helps it defend itself from any predators looking to snack on a crab leg or two. What's really bizarre is that the creature shown above is actually a type of hermit crab, and has gotten rid of its own shell to live in this one!
2. Peanut Worm
The peanut worm, known by scientists as the Sipuncula, is a deep-sea worm that has a body that oddly resembles a phallus. When a peanut worm feels it is in danger, it will contract its long head inwards, which will result in it looking like a peanut. Interestingly, peanut worms are able to reproduce both asexually and sexually.
3. Cookiecutter Shark
Here's one you're probably glad you'll never encounter. This bioluminescent shark has rows of neatly-arranged serrated teeth, and preys on dolphins, big fish, and even the occasional whale. They attack their prey by latching onto them, before repeatedly biting out cookie-sized chunks of flesh. Ouch!
4. Lizard Fish
Just one look at the lizard fish is enough to make even the bravest souls among us get goosebumps. Thankfully though, they are rarely seen, and when they are spotted they are usually alone. This is because they live in places where there is very little food available, which means they have to spread themselves out far and wide in order to survive.
5. Blob Fish
This slimy creature was picked up from the depths below New South Wales. It has got very soft and slippery skin, and is known to be an ambush predator, meaning that it lies very still hidden within the sand, and strikes as soon as an unsuspecting victim passes by.
6. Faceless Fish
This weird fish has no eyes whatsoever, which is why it is commonly referred to as a faceless fish. It was first discovered over 140 years ago, during the first ever round-the-world oceanographic expedition led by the crew of the HMS Challenger.
With an oddly mesmerizing look, these creatures are fascinating to observe if you ever get the chance. Interestingly, they belong to the same group as jellyfish, anemones, coral, and other tentacled sea creatures.
8. Brittle Star
This unique type of starfish can be found in seas and oceans all over the planet, and have been spotted anywhere from Antarctica to Siberia. They are extremely mysterious creatures, and scientists have never managed to learn too much about them.
9. Giant Anemone-Sucking Sea Spiders
Don't let the name fool you, these terrifying creatures aren't spiders at all, but are actually some of the most ancient arthropods still living to this day. They are very simple creatures, and are not really much more than a set of tubes connected together. However, many of them actually have legs that glow in the dark to help them navigate and hunt in the darkest areas of the ocean.
The creature you can see above is an amphipod, which is a kind of flesh-eating crustacean. They are deep-sea scavengers and will consume anything nutritious that they encounter, no matter how big or small!
Make sure you share these fascinating creatures with your friends and family!
