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 ...
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 ...
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 ...
e. The biological pump (or ocean carbon biological pump or marine biological carbon pump) is the ocean's biologically driven sequestration of carbon from the atmosphere and land runoff to the ocean interior and seafloor sediments. [1] In other words, it is a biologically mediated process which results in the sequestering of carbon in the deep ...
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 ...
Antarctic fishes. Antarctic fish is a common name for a variety of fish that inhabit the Southern Ocean. There are relatively few families in this region, the most species-rich being the Liparidae (snailfishes), followed by Nototheniidae (cod icefishes). [1] The latter is one of eight different families that belong to the suborder ...
