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.
Deep-sea organisms generally inhabit bathypelagic (1-4 km, 0.6-2.5 mi deep) and abyssopelagic (4-6 km, 2.5-3.7 mi deep) zones. However, characteristics of deep-sea organisms, such as bioluminescence can be seen in the mesopelagic (200-1,000 m, 650-3,300 ft deep) zone as well. The mesopelagic zone is the disphotic zone, meaning light there is ...
The evidence suggests that deep-sea hydrothermal vent viral evolutionary strategies promote prolonged host integration, favoring a form of mutualism rather than classic parasitism. [ 32 ] As hydrothermal vents outlets [ clarification needed ] for sub-seafloor material, there is also likely a connection between vent viruses and those in the crust.
• Sea snake (bottom right) Marine reptiles are reptiles which have become secondarily adapted for an aquatic or semiaquatic life in a marine environment. Only about 100 of the 12,000 extant reptile species and subspecies are classed as marine reptiles, including marine iguanas, sea snakes, sea turtles and saltwater crocodiles. [1]
From shallow waters to the deep sea, the open ocean to rivers and lakes, numerous terrestrial and marine species depend on the surface ecosystem and the organisms found there. [ 1 ] The ocean's surface acts like a skin between the atmosphere above and the water below, and hosts an ecosystem unique to this environment.
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 ...
From shallow waters to the deep sea, the open ocean to rivers and lakes, numerous terrestrial and marine species depend on the surface ecosystem and the organisms found there. [ 28 ] The ocean's surface acts like a skin between the atmosphere above and the water below, and harbours an ecosystem unique to this environment.
[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 ...
