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 ...
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.
[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 ...

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 mysid, Gnathophausia spp. Mesopelagic zooplankton have unique adaptations for the low light. Bioluminescence is a very common strategy in many zooplankton. This light production is thought to function as a form of communication between conspecifics, prey attraction, prey deterrence, and/or reproduction strategy. [8]
Deep-sea chimaera photographed by the NOAAS Okeanos Explorer.Visible on its snout are tiny pores which lead to electroreceptor cells.. Chimaeras are soft-bodied, shark-like fish with bulky heads and long, tapered tails; measured from the tail, they can grow up to 150 cm (4.9 ft) in length.
Marine deep sea polychaetes under the genus Osedax will colonize at whale falls in many different oceans, using a symbiont that can digest the bones within the carcasses (Jones et al,2007) This earned them the common name of "boneworms," and they are speculated to be a keystone species of these types of environments due to lack of organisms in ...
