Which zone of the water body will be richest in terms of biodiversity?
Like ponds and lakes, the ocean regions are separated into separate zones: intertidal, pelagic, abyssal, and benthic. All four zones have a great diversity of species. Some say that the ocean contains the richest diversity of species even though it contains fewer species than there are on land.
What animals live in the bathyal zone?
The bathyal zone contains sharks, squid, octopuses, and many different species of fish. This includes deep-water anglerfish, gulper eel, amphipods and dragonfish.
How deep is the Abyssopelagic zone?
The Abyssopelagic Zone (or abyssal zone) extends from 13,100 feet (4,000 meters) to 19,700 feet (6,000 meters). It is the pitch-black bottom layer of the ocean. The name (abyss) comes from a Greek word meaning “no bottom” because they thought the ocean was bottomless.
What fish live in the abyssal zone?
The species that live the abyssal zone include the black swallower, tripod fish, deep sea anglerfish, and the giant squid. These animals are able to withstand the pressures of the ocean depths which can be up to 76 megapascals or 11,000 psi.
Who has been to the hadal zone?
They are both extremely remote and dark. Only three people in history have seen them in person. Marine biologists hope to save these depths from destruction before it is too late. Much like Orpheus, they are seeking to save something precious that has been beyond the reach of humanity.
Can humans go to the hadal zone?
The entire ocean is like that, but the hadal depths have obscurity in spades. More than 98 percent of the ocean is above 6,500 meters depth, which we can reach with a fair number of human-occupied, remotely operated, and autonomous underwater vehicles.
Is underwater darkness?
It’s dark down there at the bottom of the sea—darker than you can probably even imagine! Let me explain… The ocean is very, very deep; light can only penetrate so far below the surface of the ocean. As the light energy travels through the water, the molecules in the water scatter and absorb it.
Why does water get darker the deeper you go?
In very deep water, almost all of the sun’s rays are absorbed by the water itself due to the lack of sediment and the lower amount of organic matter (like algae and jellyfish), and thus the blue appears to be darker.
Can you see underwater in the ocean?
Basically a camera lens or our eye is able to focus by refracting light rays. If we attempt to see underwater with the naked eye, we lose the ability to pre-focus an image since seawater and the liquid in our eyes have virtually the same refractive index.
