What is the difference between deep sea creatures and those that live near the surface?

Organisms living in the deep ocean must survive in a physical environment that is radically different from ocean habitats near the sea surface. Light is virtually absent in the deep ocean, which means that deep-sea organisms cannot rely on vision for feeding, avoiding being eaten, or mating.

What are some reasons much of the ocean has not been explored?

“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.

Do you think that all ocean basins have the same physical features Why or why not?

The ocean basins constitute one of the two major topographic features of Earth’s surface, the other being the continents. Yet, they all contain certain common features such as oceanic ridges, trenches, and fracture zones and cracks, abyssal plains and hills, seamounts and guyots.

What happens when deep sea creatures are brought to the surface?

Bring a fish from depth to the surface and these gases come out of solution resulting in decompression sickness or a gas embolism. Also the density of these gases within solution changes as depth changes and messes with their breathing chemistry.

What makes the deep sea unique?

The deep-sea is defined as the part of the ocean below 200 meters depth. This environment Is considered extremely harsh with temperatures of below 5 degrees Celsius, extreme pressure (2,000 meters equals about 200 times the atmospheric pressure at sea level), and no sunlight.

Did you know about the ocean?

Our oceans cover more than 70 per cent of the Earth’s surface. With so much of the Earth’s surface taken up by ocean, it’s evident how vital these marine environments are to the planet, and how much there still is to be explored.

How would you characterize the general shape of an ocean basin?

How would you characterize the general shape of an ocean basin? Ocean basins are not bathtub-shaped. The submerged edges of continents form shelves at basin margins, and the center of a basin is often raised by a ridge.

How many sea creatures have been discovered and classified?

There is also an incredible variety of sea creatures yet to be discovered and classified. The amazing thing about sea life is the incredible biodiversity exhibited by the oceanic ecosystem. This is evident in the fact that 297 new species of sea creatures were discovered on a single volcanic rock column in the ocean.

How many species of life exist in the ocean?

In fact, we don’t even know how many species exist in the oceans. Most estimates were made before we even had any inventory of how many had been scientifically named – they have ranged from 0.3m to an astounding 100m.

Are there any odd-looking sea creatures?

Not all sea creatures are blessed with good looks. In fact, odd-looking sea creatures, like the flabby blobfish and spooky frilled shark, make up the vast majority of marine fauna.

What are the most bizarre sea creatures in the world?

Allow us to introduce you to nine of the most bizarre sea creatures lurking in the world’s oceans, from the shallows to the deep abyss. First on the list is the bobbit worm, arguably one of the most terrifying and bizarre sea creatures living within the seabed.
