The deep ocean truly is a world all its own. The term deep sea creature refers to animals that live below the photic zone of the ocean. There, the water is pitch black and cold. In addition, the water pressure is so intense that humans could not survive. As a result, the extreme environment in the deep sea has forced sea creatures that live there to evolve in order to ensure their survival. Similarly, some of the deep sea creatures look super strange to humans. These creatures must survive in extremely harsh conditions with small amounts of oxygen, very little food, no sunlight, and extreme cold. Keep reading more below about some of the scariest monsters of the deep sea.

The Scariest Monsters of the Deep Sea

Top 5 Scary Sea Monster Myths
  • Red Octopus – The Red Octopus is the most common shallow-water octopus and lives in waters off the North American West Coast. Just beneath their skin, octopuses have thousands of cells known as chromatophores that contain tiny sacs filled with either a red, orange, brown, yellow or black pigment. When the red octopus stretches or squeezes the sacs, they can rapidly change the brightness of each color. Also, red octopus have sharp beaks and will bite their victim and then spit venom on the wound. In addition, the healing process after a red octopus bite can take up to three weeks. This is one of the scariest monsters of the sea.
  • Deep Sea Blob Sculpin – The blob sculpin is a species of deep-sea fish of the family known as Psychrolutidae. The blob sculpin diet primarily consists of crustaceans, molluscs, and sea pens. It lives off the continental shelves in very deep water in the North Pacific Ocean by the coasts of Japan, the Bering Sea, and California. As far as size, the blob sculpin can grow to about 70 cm in length which is around  2 feet long.  
  • Sea Pigs Sea pigs are actually sea cucumbers that have a striking resemblance to a pig. They have translucent, pink-tinged bodies with several pairs of elongated tube feet. Sea pigs live in some of the deepest, darkest parts of the ocean and have delicate, water-filled bodies that nearly disintegrate when brought up from these extreme depths. They tend to live between 4,000 to 16,000 feet below the surface and are difficult to study since they are rarely seen.  
  • Goblin Shark – The goblin shark is a rare species of deep-sea shark that has also been referred to as a “living fossil.”  The only living species of the family Mitsukurinidae, their lineage goes back nearly 125 million years old. These pink animals can grow up to 12 feet long and weigh more than 450 pounds. They have narrow snouts and fang-like teeth, and were named after mythical goblins from Japanese folklore.  
  • Proboscis Worm  – Also known as ribbon worms, proboscis worms are very slim and only measure a few millimeters wide with relatively short, wide bodies. In terms of coloring, they have varying patterns of yellow, orange, red and green. The ribbon worm uses its proboscis when hunting by vomiting a thick and sticky substance from a feeding tube sheath above its mouth. The mucus has a neurotoxin substance in it that paralyzes its prey.  
  • Zombie Worms  – Commonly called boneworms, zombie worms, or bone-eating worms, zombie worms are known for boring into the bones of whale carcasses to reach the inside fat for sustenance. Also known as Osedax worms, they specialize in eating the hardest parts of a whale carcass: the bones. These unusual worms have no mouth nor stomach and survive entirely on the bones of fallen animals, especially whales.
  • Stonefish – Lastly, the stonefish is a genus of ray-finned fish belonging to the subfamily Synanceiidae. Stonefishes are venomous, dangerous, and even fatal to humans. In fact, the venom that is produced by stonefish is some of the most venomous in the world, and is fatal to humans. For a complete recovery, a sufficient amount of anti-venom is required quickly to reverse the effects, which include excruciating pain and swelling at the bite site.

The Ugliest Fish in the Sea – The Blobfish

The blobfish is a unique species of fish that lives deep within the ocean. As a result, it is rarely seen. Many people have compared the blobfish to Jabba the Hutt from Star Wars in terms of its appearance. Voted the world’s ugliest animal, the circulatory system of a blobfish is very similar to other deep sea species of fish with a single, closed circulatory system. As a result, blood is contained within the vessels and passes through the heart only once as it circulates throughout  the body. Additionally, blobfish don’t have any known natural predators besides humans. In fact, the most common cause of death for blobfish is getting caught in deep-sea trawling nets and rising to the surface. While the exact lifespan of blobfish is unknown, many scientists believe they may live for over 100 years because of their slow rate of growth and lack of predators.
