[1] [2] Conditions within the deep sea are a combination of low temperatures, darkness, and high pressure. [3] The deep sea is considered the least explored Earth biome as the extreme conditions make the environment difficult to access and explore. [4] Organisms living within the deep sea have a variety of adaptations to survive in these ...
Deep sea mining operations could cause problems for the abyssal zone in the future. The talks and planning for this industry [clarification needed] are already under way. Deep sea mining could be disastrous for this extremely fragile ecosystem since there are many ecological dangers posed by mining for deep sea minerals.
In zoology, deep-sea gigantism or abyssal gigantism is the tendency for species of deep-sea dwelling animals to be larger than their shallower-water relatives across a large taxonomic range. Proposed explanations for this type of gigantism include necessary adaptation to colder temperature, food scarcity, reduced predation pressure and ...
For the deep-sea ecosystem, the death of a whale is the most important event. A dead whale can bring hundreds of tons of organic matter to the bottom. Whale fall community progresses through three stages: [32] Mobile scavenger stage: Big and mobile deep-sea animals arrive at the site almost immediately after whales fall on the bottom.
A piezophile (from Greek "piezo-" for pressure and "-phile" for loving) is an organism with optimal growth under high hydrostatic pressure, i.e., an organism that has its maximum rate of growth at a hydrostatic pressure equal to or above 10 megapascals (99 atm; 1,500 psi), when tested over all permissible temperatures.

Rhinochimera atlantica Gigantactis is a deep-sea fish with a dorsal fin whose first filament has become very long and is tipped with a bioluminescent photophore lure. Pelican eel Bigeye tuna cruise the epipelagic zone at night and the mesopelagic zone during the day. The fish of the deep-sea have evolved various adaptations to survive in this ...
Due to the scarcity of food in the deep sea environment, a majority of siphonophore species function in a sit-and-wait tactic for food. [22] The gelatinous body plan allows for flexibility when catching prey, but the gelatinous adaptations are based on habitat. [23] They swim around waiting for their long tentacles to encounter prey.
At the continental shelf edge, usually about 200 metres (660 ft) deep, the gradient greatly increases and is known as the continental slope. The continental slope drops down to the deep sea floor. The deep-sea floor is called the abyssal plain and is usually about 4,000 metres (13,000 ft) deep.
