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 ...
The deep sea is broadly defined as the ocean depth where light begins to fade, at an approximate depth of 200 m (660 ft) or the point of transition from continental shelves to continental slopes. [ 1 ][ 2 ] Conditions within the deep sea are a combination of low temperatures, darkness, and high pressure. [ 3 ]
Thus a very high gas pressure of oxygen can be obtained, which can even account for the presence of gas in the swim bladders of deep sea fish like the eel, requiring a pressure of hundreds of bars. [5] Elsewhere, at a similar structure known as the 'oval window', the bladder is in contact with blood and the oxygen can diffuse back out again.
t. e. The mesopelagiczone (Greek μέσον, middle), also known as the middle pelagic or twilight zone, is the part of the pelagic zone that lies between the photic epipelagic and the aphotic bathypelagic zones. [ 1 ] It is defined by light, and begins at the depth where only 1% of incident light reaches and ends where there is no light; the ...
The adults live on the sea floor, between 100 and 2,800 m (330 and 9,190 ft) deep, [7] [8] The intense biological pressure to conserve energy within deep sea fish seems to be true across many species; most of them are long lived, have a slow rate of reproduction, growth, and aging. Furthermore, studies have shown that the Psychrolutidae species ...
Psychrolutes microporos. J. S. Nelson, 1995 [ 1 ] Psychrolutes microporos is a species of deepwater marine fish in the family Psychrolutidae, commonly known as a blobfish or fathead. It is found in the abyssal zone in waters around Australia and New Zealand. A photograph of an individual taken in 2003 has become famous on the internet.
The fish can grow to more than 30 feet long, and have large eyes and "foreboding" red spines in a crown-like cluster. Typically, these fish are deep-sea dwellers and thrive in waters that are the ...
