For example, some make an extreme effort to see, building huge bulbous eyes that can detect even the smallest glimmer of light, while others completely forfeit any form of sight and instead rely on heightened scent and touch. As coastal and open-water fisheries become depleted, industrial fishing operations have increasingly turned to exploiting deep sea species. Industrial fishing now covers 55% of the ocean area (Kroodsma et al., 2018). The main method used is bottom trawling –  dragging huge nets armed with steel plates and heavy rollers across the seabed, pulverising everything in their path to catch one or two species of commercial value.

Deep Sea

• The small island republic has followed this request and has protected their black smokers.
• And finally, the deepest reaches of the ocean are found at the bottom of precipitous trenches.
• By the time the ocean returned to that region, sediment had covered the salt, isolating it from the seawater.
• The world’s oceans have roughly 300 times more area to support life an do the world’s continents.
• Deep-sea animals have had to evolve, often through unusual and unique adapations, to live, reproduce, and thrive in these unique conditions.

The snailfish boasts «a distinctive pink color and a bumpy texture,» according to the video. Because many of these “underwater islands” are located in remote surroundings, studies are continually finding previously unknown and endemic species. At the Deep Sea Conservation Coalition, we believe that protecting the deep sea starts with understanding it. The Knowledge Hub is your gateway to discovering the wonders of the deep, and learning how this hidden world is connected to all of us. Remotely operated vehicle Deep Discoverer explores the Mariana Trench at the depth of 6,000 meters (3.7 miles).

This Adorable Bumpy Snailfish Is One of Three New Species Discovered in the Deep-Sea

• In order to work, scientifically, deep sea mining must extract larger quantities.
• Packages and bags have been discovered that have apparently been on the seafloor for decades, virtually untouched by time.
• Their closest living relatives are sharks, but they branched off from the evolutionary line about 400 million years ago and are among the most primitive fish.
• Animal life at a hydrothermal vent relies on the energy produced by symbiotic bacteria.
• Fish, too, find shelter within the canyon walls, and also a good place to catch a meal.

The timeframe required for the re-establishing of communities depends highly on the size of the region in question. The possible effects of the perturbation caused by the re-entering of sediment collected together with the nodules on the zoo- and phyto-plankton as well as other Deep Sea marine organisms in surface-near water layers are not known yet. It cannot be excluded that the planktonic organisms, fish, whales and dolphins may be especially affected through this. It is now possible to also create MPAs in the open ocean and the deep sea. Other fragile ecosystems, such as the seamounts or the species rich deep sea coral reefs for example, should, following the Azoran example, be placed under protection very soon.

WHY WE ALL NEED THE DEEP

Recent scientific discoveries are revealing how important the deep ocean is to our planet. It is at the heart of Earth’s climate system, playing a central role in regulating currents and climate and storing the carbon that might otherwise cause global heating. They do so by taking great gulps of air through their blow holes when they’re at the surface. This air moves into the lungs, but as the whale dives deeper the pressure forces air into special sinuses filled with fatty oils. The air mixes up with these oils making an emulsion, so that it cannot be crushed.

And last but not least, many deep-sea organisms have large eyes, helping them pick up the tiny amounts of residual light in the water or the light signals put out by other fauna. It may be the last place you’d expect to find corals—up to 6,000 m (20,000 ft) below the ocean’s surface where the water is icy cold and completely dark. In fact, there are as many known species of deep-sea corals (also known as cold-water corals) as shallow-water species. Like shallow-water corals, deep-sea corals may exist as individual coral polyps, as diversely-shaped colonies containing many polyps of the same individual, and as reefs with many colonies made up of one or more species.

Further investigation into these unique habitats showed that many of the other creatures that live by the vents also rely on symbiotic bacteria. The yeti crab waves its arms in the water to help cultivate bacteria on tiny arm hairs which it then consumes. The Abyssopelagic extends from 13,100 to 19,700 feet (4,000-6,000 m) down to the seafloor or abyssal plain. Animals that can withstand the pressures in this depth, which can reach up to 600 times what is experienced at sea level are highly specialized.
They discovered hot vents, regions where water with more than 350°C streams out of the ocean floor and provides habitat for organisms such as bacteria and tubeworms, at 2.500 m depth close to the Galapagos Islands. The characteristics of this ecosystem are so similar to those of creatures that are sunlight dependent, that they created an entirely new field of research. Below the ocean’s surface is a mysterious world that accounts for over 95 percent of Earth’s living space—it could hide 20 Washington Monuments stacked on top of each other. As you dive down through this vast living space you notice that light starts fading rapidly.

The Challenge of Depth: Describing and Protecting Deep-Sea Species

Once damaged, deep-sea habitats can take centuries to recover, and entire deep-sea species can be lost forever before we even know they exist. The effects of the ocean system through oil mining stretches from local pollution (through sound or oil) to far past the platforms (through carbon dioxide and other toxicants). After successfully fighting against the demolition and sinking of the disused ‘Brent Spar’ Platform through environmental activists there is a European law against the destruction of the metal giants in the ocean. However, the oil industry still does their part in the problem of environmental pollution.
