How do creatures survive in the deep-sea?
The term deep sea creature refers to organisms that live below the photic zone of the ocean. These creatures must survive in extremely harsh conditions, such as hundreds of bars of pressure, small amounts of oxygen, very little food, no sunlight, and constant, extreme cold.
Are there undiscovered sea creatures?
Up to a million species live in the seas, and two-thirds of those ocean-dwellers may still be undiscovered, according to a new study that also cataloged all of the known species that dwell beneath the waves.
Are there animals in the deepest part of the ocean?
Mariana hadal snailfish (Pseudoliparis swirei) have been spotted as deep as 26,831 feet, more than 5 miles below the surface, in the Mariana Trench. This habitat, called the hadal zone, lends its name to the fish. These fish may look like cute tadpoles, but they are the top predators in their habitat.
Why are deep sea creatures scary?
Why Do Deep Sea Creatures Look So Scary? Anna Rothschild of Gross Science explains how different it is at the bottom of the sea: Food can be scarce, there’s tremendous ocean pressure, and it’s dark.
What is the scariest sea creature?

How much of the ocean is unexplored?
Ocean Waves. The ocean covers more than 70 percent of Earth, and more than 80 percent of it remains unexplored.
What would happen to a human body at the bottom of the ocean?
The pressure from the water would push in on the person’s body, causing any space that’s filled with air to collapse. (The air would be compressed.) So, the lungs would collapse.
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.
What lives on the ocean floor?
The dominant species are crustaceans, fish and a variety of animals with soft and jelly-like bodies such as jellyfish. The deep-sea floor is covered with many mounds and depressions formed by benthic animals such as worms, mollusks, crustaceans, starfish, brittlestars, shrimps, fishes sea cucumbers and sea urchins.
How do animals see at the bottom of the ocean?
So they use echolocation. They use a clicking-style of echolocation that lets that bounces back signals so they can “see” other animals in dark waters.
How deep can humans go in the ocean?
How deep in the ocean can the human body go? That means that most people can dive up to a maximum of 60 feet safely. For most swimmers, a depth of 20 feet (6.09 metres) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 metres) when exploring underwater reefs.
What happens if you go too deep in the ocean?
As you descend, water pressure increases, and the volume of air in your body decreases. This can cause problems such as sinus pain or a ruptured eardrum. As you ascend, water pressure decreases, and the air in your lungs expands. This can make the air sacs in your lungs rupture and make it hard for you to breathe.
What’s under the ocean floor?
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.
What lives in the bottom of the Mariana Trench?
The organisms discovered in the Mariana Trench include bacteria, crustaceans, sea cucumbers, octopuses and fishes. In 2014, the deepest living fish, at the depth of 8000 meters, Mariana snailfish was discovered near Guam.
Is the ocean scarier than space?
JoAnna Wendel, science writer. “The ocean is 100 percent scarier. Space is just a bunch of rocks and like … depth.”
Are there giant monsters in the ocean?
But scientists believe the world’s oceans are still hiding giant underwater creatures which have yet to be discovered. Marine ecologists have predicted there could be as many as 18 unknown species, with body lengths greater than 1.8 metres, still swimming in the great expanses of unexplored sea.
Is there a bottom to the ocean?
The average depth of the ocean is about 3,688 meters (12,100 feet). The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam.
How much pee is in the ocean?
The volume of the Atlantic Ocean is about 350 quintillion liters. That’s 350 and 18 zeroes. If every person on earth had the average amount of pee containing the average amount of urea into the Atlantic, there’d be just 60 parts per trillion of urea in the ocean.
Why is the ocean so weird?
Down at the ocean floor, the environment is not hospitable. It is cold, except near thermal vents. In addition, it is so dark that no plants can live there, and the weight of the water far exceeds anything human bodies can handle.
Do deep sea fish have eyes?
Fish living in the deep ocean have evolved highly-sensitive eyes that can see a range of colour hues in the near-darkness. “It’s a big surprise,” says Zuzana Musilova at the University of Basel in Switzerland. “They have more sensitive eyes and can see way better than humans in lower light.”

Is there a underwater city?
Dwarka, India
Also known as the Gateway to Heaven, the city of Dwarka was, reportedly, discovered in 1988, submerged around 100 ft below the Gulf of Cambay.
Why is the ocean salty?
Ocean salt primarily comes from rocks on land and openings in the seafloor. Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks.
Why is the ocean blue?
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.
How long can the human body stay submerged in water?
Without the supply of oxygen, the body shuts down. The average person can hold their breath for around 30 seconds. For children, the length is even shorter. A person who’s in excellent health and has training for underwater emergencies can still usually hold their breath for only 2 minutes.
How do sperm whales dive so deep?
Spermaceti is the main component of sperm whale organ which allows the animal to dive so deeply. The whale is able to close off the blood supply, whereby the spermaceti cools off to the point of solidifying. The density increases, allowing the whale to dive more readily.
Can you dive down to see the Titanic?
So, can you scuba dive to the Titanic? No, you cannot scuba dive to the Titanic. The Titanic lies in 12,500 feet of ice cold Atlantic ocean and the maximum depth a human can scuba dive is between 400 to 1000 feet because of water pressure. The increasing water pressure also restricts blood flow by constricting tissue.
Has anyone touched the bottom of Mariana Trench?
The first and only time humans descended into the Challenger Deep was more than 50 years ago. In 1960, Jacques Piccard and Navy Lt. Don Walsh reached this goal in a U.S. Navy submersible, a bathyscaphe called the Trieste.
How long does it take for a body to decompose in a coffin?
If the coffin is sealed in a very wet, heavy clay ground, the body tends to last longer because the air is not getting to the deceased. If the ground is light, dry soil, decomposition is quicker. Generally speaking, a body takes 10 or 15 years to decompose to a skeleton.
How deep can a human go in the ocean without dying?
For most swimmers, a depth of 20 feet (6.09 metres) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 metres) when exploring underwater reefs. When free diving the body goes through several changes to help with acclimatisation.
Why can’t submarines go to the bottom of the ocean?
The problem for U.S. subs isn’t the temperature or pressure in these zones; it’s what is actually on the seafloor that can cause trouble for nuclear submarines. Rocks or other unseen objects can cause massive damage to the hull of a submarine, tearing up its vents, stealth cover, or steering.
How dark is it at the bottom of the ocean?
After the aphotic zone, there’s complete darkness. From 1,000 meters below the surface, all the way to the sea floor, no sunlight penetrates the darkness; and because photosynthesis can’t take place, there are no plants, either.
Why is so much of the ocean unexplored?
“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.
How do fish see underwater at night?
Fish living in the deep sea manage to navigate in complete darkness. It’s not strictly ‘seeing’ but fish have rows of pressure-sensitive organs running down each side of their body called the lateral line, which allows them to sense nearby animals from the pressure changes in the water.
Can humans survive in the Mariana Trench?
You would never make it to the bottom of the ocean without any equipment, because you would run out of oxygen, and your body would be shut down by the pressure underwater. So if you want any chance of surviving this journey, you’ll need some sort of capsule to bring you safely to the bottom.
Why is ocean so deep?
The extreme depth of the Mariana Trench and other oceanic trenches is caused by subduction – where on the boundary of two converging tectonic plates, one descends down into Earth’s mantle, creating a deep trough.
What youngest part of the ocean floor is found?
The youngest crust of the ocean floor can be found near the seafloor spreading centers or mid-ocean ridges. As the plates split apart, magma rises from below the Earth’s surface to fill in the empty void.
Does the sea has an end?
While this question appears to have a simple answer, the reality is that all the world’s waterways are connected to each other. There are no borders within the water itself, rather the names were human constructs given to different oceans in regard to around which bodies of land they flow.
Why are there straight lines on the ocean floor?
These lines are artifacts of the ocean floor mapping process. Oceanographers use sonar—sound waves—to map the ocean bottom. These sonar readings are typically taken by ships towing submersible devices that send out sound waves.
Are there monsters in the Mariana Trench?
Despite its immense distance from everywhere else, life seems to be abundant in the Trench. Recent expeditions have found myriad creatures living out their lives at the bottom of the sea-floor. Xenophyophores, amphipods, and holothurians (not the names of alien species, I promise) all call the trench home.
Is Megalodon in the Mariana Trench?

Is there anything deeper than the Mariana Trench?
The deepest place in the Atlantic is in the Puerto Rico Trench, a place called Brownson Deep at 8,378m. The expedition also confirmed the second deepest location in the Pacific, behind the Challenger Deep in the Mariana Trench. This runner-up is the Horizon Deep in the Tonga Trench with a depth of 10,816m.

Is the ocean floor hot?
No matter how warm the surface of the ocean gets, the ocean’s huge volume and deep basins keep temperatures at the bottom of the ocean at only slightly above freezing. At the abyssal zone, the part of the sea closest to the vents, it’s way too cold to even dip a pinky into the water.
How much of the ocean is unexplored?
Ocean Waves. The ocean covers more than 70 percent of Earth, and more than 80 percent of it remains unexplored.
How old are the ocean?
Joly, with Murray’s figures for rainfall, run-off, and the average composition of river water, combined with Dittmar’s analyses of oceanic salts and an estimate of the mass of the ocean, deduced an uncorrected value for the age of the ocean of 97,600,000 years.
Is it OK to poop in the ocean?
People usually recover without problems, but dehydration is a concern, and may rarely result in hospitalization. Human sewage in the ocean can cause human illnesses. causes nausea, vomiting, diarrhea, stomach pain, and sometimes fever.
Are sharks attracted to pee?
Well, we contacted the world experts from the International Shark Attack File in Florida. Like us – they found no evidence urine attracts sharks.
