This strange deep sea creature was discovered in the year 2007 between Indonesia and Philippines, on the area named “Coral Triangle”. The squidworm has 10 tentacle-like appendages on its head, which are all longer than its own body. These appendages are used to collect food, which is usually a dead particulate organic material or detritus falling in the water.

They are named sea pens because of their close resemblance to the feather-like antique quill pens that were used centuries ago. These strange deep sea creatures are found on the shallow waters of Long Sound, New Zealand and are still living in colonies. They have root-like penduncles which help them to attach themselves on the seafloor. The best part about sea pens is that they have the ability to re-locate and re-attach themselves if necessary.

Chances are that you may have seen a salp in your life but you would not have known why it is named such. Salps are often seen in cold and pleasant seas. They swim individually but most often, they attach themselves to fellow salps to create and produce a long line of colony.

Since salps condense their waste products into carbon-containing pellets, they effectively remove carbon from the water surface and play an important role in carbon cycling. Isn’t this amazing?

4. Sea Pig

This may be one of the strangest looking creatures under the sea. Sea pigs have enlarged tube-like feet that look like a human leg. They feed themselves by extracting organic particles from deep-sea mud and they use their olfactory senses to find their food. They live at the very bottom of the ocean and are the most plentiful creatures down there. However, many in numbers as they are, they may face extinction because of deep-see trawler which can catch and kill 300 sea pigs in just one single move.

5. Christmas Tree Worm

Who says that there are no Christmases under the sea? Well, that notion needs to be changed once you see this weird Christmas tree worm. It is right there underwater all year round. This sea creature is named Christmas Tree Worm because they have two “crowns”, which are shaped like a Christmas tree and the worm can mean the spiral structure of this specie. This sea creature is usually found at the Great Barrier Reef’s Lizard Island and are commonly seen embedded on the heads of massive corals.

This specie is the remaining member of a lineage from 125 million years ago and is also called “living fossil”. Goblin sharks have rare contacts with humans because they live deep in the sea. Hence, they are not well known compared to the other sea creatures mentioned in this article. One distinctive feature is their long and flat snout which closely resembles a sword blade. Since this creature has minimum contact with humans, there is little information available about their lifestyle and beginnings.

7. Blobfish

At a first glance, a blobfish might scare you if you are not familiar with it. They can be found off the water coasts of mainland Australia, Tasmania and New Zealand. They are one among those strange deep sea creatures without any skeleton and muscles. The blobfish is made up of jelly-like flesh, which is less dense in water, making them to withstand the pressure deep in the sea. Blobfishes are often caught by trawling which will be the main reason for their extinction.

8. Dumbo Octopus

A basket star is actually a group of brittle stars. As most of the strange deep sea creatures in this article, a basket star also lives deep in the sea and can last up to 35 years without any external interference. A basket star has 5 arms budding from their central disk, however, each of these arms branch out again and again until they are kind of mixed-up into a basket, hence the name basket star.

22. Axolotl

Strange Deep Sea Creatures

An axolotl may look quite strange but it is very popular. They are closely related to a salamander and also called the Mexican walking fish. As a matter of fact, axolotls are already considered oen among the endangered species, as there were many attempts to breed them and release them back into the wild. Axolotl is a carnivore. It feeds on worms, insects and small fishes.

These underwater sea creatures are the strangest of their kinds. Some of you may be already familiar with them because they are commonly seen on some parts of the world while some maybe rare and most often than not, they isolate themselves and stay at the deepest part of the ocean. No matter how they look, no matter where they are, these strange sea creatures are a part of the biodiversity and ecology that lets marine life survive on their own.

Some of these creatures are already extinct or on the verge of extinction because of human interventions like deep sea trawling and divers who take a fancy on how they look and take them out of their natural habitat. Marine life is very different from our own. With this, it is better if we leave what belongs to the sea into the sea. Once we take them out from their natural habitat and put them on our huge aquariums, we are actually altering the way they live. Eventually, they die. Once they face extinction, it might greatly affect other marine lives under the sea which in turn will also affect our lives as humans. We may not experience it now, but we certainly would not want our grandchildren and their children to suffer the consequences of our actions. These creatures may look weird, strange, and at times scary, but surely they deserve to live and should be taken care of.
