Deep-sea fish. Deep-sea fish are fish that live in the darkness below the sunlit surface waters, that is below the epipelagic or photic zone of the sea. The lanternfish is, by far, the most common deep-sea fish. Other deep-sea fishes include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, viperfish, and some species of eelpout.
A deep-sea community is any community of organisms associated by a shared habitat in the deep sea. Deep sea communities remain largely unexplored, due to the technological and logistical challenges and expense involved in visiting this remote biome. Because of the unique challenges (particularly the high barometric pressure, extremes of ...
Cyclothone is a genus containing 13 extant species of bioluminescent fish, commonly known as ' bristlemouths ' or 'bristlefishes' due to their shared characteristic of sharp, bristle-like teeth. These fishes typically grow to around 1-3 inches, though some can be larger. They are most commonly found in the mesopelagic zone of the ocean, mostly ...
A marine habitat is a habitat that supports marine life. Marine life depends in some way on the saltwater that is in the sea (the term marine comes from the Latin mare, meaning sea or ocean). A habitat is an ecological or environmental area inhabited by one or more living species. [1] The marine environment supports many kinds of these habitats.
The oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf (e.g. the neritic zone), but operationally is often referred to as beginning where the water depths drop to below 200 metres (660 ft), seaward from the coast into the open ocean with its pelagic zone. It is the region of open sea beyond the edge of ...
Krill(Euphausiids)[ 1 ] (sg.: krill) are small and exclusively marine crustaceans of the order Euphausiacea, found in all the world's oceans. [ 2 ] The name "krill" comes from the Norwegian word krill, meaning "small fry of fish", [ 3 ] which is also often attributed to species of fish. Krill are considered an important trophic level connection ...
Pseudoliparis swirei, the Mariana snailfish or Mariana hadal snailfish, is a species of snailfish found at hadal depths in the Mariana Trench in the western Pacific Ocean. [2][3][4][5] It is known from a depth range of 6,198–8,076 m (20,335–26,496 ft), [6] including a capture at 7,966 m (26,135 ft), which is possibly the record for a fish ...
Of these, 1 per cent are epipelagic, 5 per cent are pelagic, and 7 per cent are deep water. [16] Fish are found in nearly all natural aquatic environments. [23] Most fish, whether by species count or abundance, live in warmer environments with relatively stable temperatures. [17] However, some species survive temperatures up to 44.6 °C (112.3 ...
