Benthic fish which can bury themselves include dragonets, flatfish and stingrays. Flatfish are an order of ray-finned benthic fishes which lie flat on the ocean floor. Examples are flounder, sole, turbot, plaice, and halibut. The adult fish of many species have both eyes on one side of the head.
“The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don’t notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth’s atmosphere, the pressure would decrease to zero.
There are estimated to be 76 species of hagfish — and some live as deep as 5,500 feet below the water’s surface. Scientists estimate that there are 76 species of hagfish, which can grow to be between 16 and 40 inches long. Some live as deep as 5,600 feet below the water’s surface.
Why does deep-sea life look so strange?
At the ocean floor, creatures are living in an environment wholly different than anywhere else on the planet. This results in animals with startling body adaptations. Deep – sea creatures have soft and watery body compositions that keep them from compressing. The pressure even affects these animals on a cellular level.
What is the scariest fish ever?
6 Sea-riously Spooky Fish Species

What is the rarest sea creature?
The vaquita is the world’s rarest sea mammal and one of the most endangered animals in the world.
At what depth will water crush you?
Human beings can withstand 3 to 4 atmospheres of pressure, or 43.5 to 58 psi. Water weighs 64 pounds per cubic foot, or one atmosphere per 33 feet of depth, and presses in from all sides. The ocean’s pressure can indeed crush you.
How deep can a human dive before being crushed?
Human bone crushes at about 11159 kg per square inch. This means we’d have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.
What is a Thalassophobia?
Thalassophobia, or a fear of the ocean, is a specific phobia that can negatively affect your quality of life. If you feel you need help overcoming your fear of the ocean, a mental health professional can help.
At what depth is the ocean dark?
It is sometimes referred to as the midnight zone or the dark zone. This zone extends from 1,000 meters (3,281 feet) down to 4,000 meters (13,124 feet). Here the only visible light is that produced by the creatures themselves. The water pressure at this depth is immense, reaching 5,850 pounds per square inch.
Which ocean is not salt water?
The ice in the Arctic and Antarctica is salt free. You may want to point out the 4 major oceans including the Atlantic, Pacific, Indian, and Arctic. Remember that the limits of the oceans are arbitrary, as there is only one global ocean. Students may ask what are the smaller salty water areas called.
The ocean floor is called the abyssal plain. Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.
Why are deep sea fish not crushed by pressure?
Under pressure Fish living closer to the surface of the ocean may have a swim bladder – that’s a large organ with air in it, which helps them float up or sink down in the water. Deep sea fish don’t have these air sacs in their bodies, which means they don’t get crushed.
Why do deep sea fish look so scary?
The pressure at the bottom of the ocean is another factor in the weird appearance of the creatures there. Cartilage and low-density flesh that doesn’t collapse under high pressure is the rule, rather than bony skeletons that would snap.
Why do deep sea creatures look creepy?
Some of them may actually be a bit deformed in the pictures because their swim bladders—the gas-filled organ that helps them move up and down through the water —expanded at surface pressure, distending their bellies.
