What are Deep Sea creatures
The creatures which live below the photic zone are called deep-sea creatures. These creatures have adapted themselves to harsh and difficult environments. These creatures live with no direct light source, lack of oxygen, high-pressure areas, lack of food, and continuous coldness in the dark abyss ocean. To live there these creatures adapted themselves for all these conditions and more because of the hadal environments in which they live.
Today’s lists include- Giant Grenadier, Chimera, Fangtooth, Angler fish, Northern Stargazer, sarcastic fringehead, Frilled Shark, Blobfish, Blue-ringed octopus, and Goblin Shark.
They are also known as ghost sharks, ratfish, or rabbitfish. This creature lives in (8,500 ft.) deep with few occurring depths shallower than (660 ft.). They basically live in every ocean except the Arctic and Antarctica. The body type of these creatures is elongated and soft with bulky heads and a single gill opening. With a length of 4.9 ft. from head to tail, this creature resembles shark and string rays. The skin type of chimera is smooth and naked with placoid scales lacking. They can be found in black to brownish gray. For defense purposes, most chimeras have a venomous spine in front of the dorsal fin. They use these fins to “fly” through the water.
9.) Sarcastic Fringehead
These are aggressive territorial fishes that are small but have largemouth. They can reach up to 12 inches long. These are mostly scaled less and are elongated and long. They swim in a confusing dart-like movement. Sarcastic fringehead is generally brown in color. They have a tendency to hide inside shells or cervices. Some were found in man-made objects like soda cans. After the female spawns under a rock or in clam burrows, the male guards the eggs. During squid spawning season, they eat large numbers of squid eggs. When these territorial creatures wrestle, they press their distended mouths against each other. This allows them to determine which is the larger fish, which can establish dominance.
8.) Giant Grenadier
They are also known as Giant rattail and Albatrossia because they have a very large tail. It is found in North Pacific from northern Japan to the Okshotsk and Bering Seas, east to the Gulf of Alaska, and south to northern Baja California in Mexico. They are found at the depths of 140 and 3,500 m. These creatures can grow up to 2.1 m in length. They have usually greatly elongated, the pointed tails of the rattails. They are an apex predator mainly preying on squids and vampire squids. Their estimated age is 8 years with a maximum age of 17 years. Usually, male giant grenadiers are found deeper than 800 m.
7.) Northern Stargazer
These fishes are found on the Atlantic shores between the states of North Carolina and New York in the United States. These can be found in the depths of 120 feet. They have a length of 56cm with a flat forehead and a lot of body mass up front near the mouth. They are blackish and brown body with white spots which appear on there head and back. The mouth of the stargazer faces up which helps to ambush prey while hiding in the sandy bottoms. They have electric organs in the orbit at the top which generates and transmit an electric shock.
6.) Blob Fish
Smooth-head fish also known as Blobfish. It inhabits the coasts of mainland Australia and Tasmania. They are typically shorter than 30 cm. They live at depths of 600 and 1,200 m. where the pressure is 60 to 120 times greater than at sea level. This makes the gas bladders inefficient for maintaining buoyancy. The flesh of the blobfish is primarily a gelatinous mass with a density slightly less than that of water. Due to this factor these fish float above the seafloor without expending energy on swimming. The blobfish has a relative lack of muscle but this is not a disadvantage as its main food source is an edible matter that floats in front of it, such as deep-ocean crustaceans.
5.) Frilled shark
A frilled shark is considered a living fossil because of its primitive anguilliform physical traits. They have dark-brown color and a 6.6ft. long body which has dorsal, pelvic, and anal fins located towards the tail. They live on the diet of smaller sharks, bony fish, and cephalopods. Frilled sharks live near the ocean floor and swim up to feed at night at the surface of the ocean. The head of the frilled shark is broad and flat, with a short rounded snout. The jaws contain 300 trident-shaped teeth, each needle-tooth has a cusp and two cusplets.
4.) Angler Fish
They are also names bony fish due to their characteristic mode of predation. The way they use luminescent fin ray acts as a lure for other fish. The luminescence comes from symbiotic bacteria which are thought to be acquired from seawater. The usual species of angler fish which lives in the deep water have large head and bear enormous crescent-shaped mouths full of long fang-like teeth angled inward for efficient prey. Most adult female certified anglerfish have a luminescent organ called the esca at the tip of a modified dorsal ray. The organ has been hypothesized to serve the obvious purpose of luring prey in dark, deep-sea environments. However, it also serves to call males’ attention to the female to facilitate mating.
They are named after their disproportionately large teeth and unapproachable visage. They are small in size and are harmless to humans. The eyes are relatively small, set high on road. The entire head is a brown to black and is strongly compressed laterally, deep anteriorly and progressively more slender towards the tail. Fins are small, simple, and spineless. It is said that the largest teeth of any animal in the ocean is of fangtooth proportionate to body size. They are so large that they can never close there mouths. Juveniles are different – unlike the adults, they possess long spines on the head and pre operculum, larger eyes, a functional gas bladder, long and slender gill rakes, much smaller and depressible teeth, and are a light grey color.
2.) Blue-ringed octopus
Blue-ringed octopuses are one of the world’s most venomous marine animals. Despite their small size of 12-20 cm. They have a relatively docile nature and they are dangerous to humans if provoked. They have a lifespan of approximately 2 years, depending upon nutrition factors, temperature, and the intensity of light in their habitat. These creatures usually live in cervices while displaying effective camouflage patterns with their dermal chromatophore cells. Just like all the other octopuses they can change their color easily, which helps them to hide into much smaller cervices. When provoked they quickly change color to bright yellow with each of the 50-60 rings flashing bright iridescent blue within a third of a second as an aposematic warning display. The rings contain multi-layer light reflectors called iridophores. These are arranged to reflect blue-green light in a wide viewing direction.
1.) Goblin Shark
These creatures are rare species of deep-sea sharks. Goblin sharks are one of the species which are considered living fossils. Some researchers believe that these sharks can live at the depths of 330 ft. These fishes can sense the electric field produced by nearby prey. Which it can snatch up by rapidly extending its jaws. Goblin sharks have a long and flat snout, resembling a blade. The proportional length of the snout decreases with age. The eyes are small and black lacking protective coverings. The goblin shark has a re-opening and re-closing pattern during the strike, a behavior that has never been seen before in other sharks. This slingshot style of feeding could be an adaptation to compensate for poor swimming ability by allowing the goblin shark to catch elusive, fast prey without having to chase the prey.
