Melanocetus murrayi was first described by the German zoologist Albert Günther in 1887 from material dredged up from the deep on the Challenger expedition of 1872 to 1876, the first scientific attempt to research the ocean depths; it was named in honour of Sir John Murray, a British biologist who took part in the expedition and was one of the founders of the new study of oceanography.
The abyssal grenadier, Coryphaenoides armatus, is an abyssal fish of the genus Coryphaenoides, found in all the world's oceans, at depths between 800 and 5,493 metres (2,625 and 18,022 ft). [3] Its adult length is 20 to 40 centimetres (8 to 16 in), although Fishbase [2] gives lengths up to 1 metre (3 ft 3 in). The abyssal grenadier's body is ...
The rattail Coryphaenoides armatus (abyssal grenadier) on the Davidson Seamount at a depth of 2,253 metres (7,392 ft). Deep-sea species exhibit lower changes of entropy and enthalpy compared to surface level organisms, since a high pressure and low temperature environment favors negative enthalpy changes and reduced dependence on entropy-driven ...
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 ...
Abyssobrotula galatheae is a species of cusk eel in the family Ophidiidae. [1] [3] It is the deepest-living fish known; one specimen, trawled from a depth of 8,370 m (27,460 ft) in the Puerto Rico Trench in 1970, holds the record for the deepest fish ever captured. [4]
The abyssal spiderfish, Bathypterois longipes, is a species of deepsea tripod fish, a demersal fish living on the bottom of the Atlantic Ocean, ...
M. johnsonii inhabits the mesopelagic and bathypelagic zones, and is found most commonly at depths between 200 and 1,500 metres (660 and 4,920 ft). [5] Compared to other species in the genus, M. johnsonii is more likely to be found at shallower depths; 65% of recorded specimens were collected at depths of or above 1,000 metres (3,300 ft) below the surface of the water.

The abyssal zone or abyssopelagic zone is a layer of the pelagic zone of the ocean. The word abyss comes from the Greek word ἄβυσσος ( ábussos ), meaning "bottomless". [ 1 ] At depths of 4,000–6,000 m (13,000–20,000 ft), [ 2 ] this zone remains in perpetual darkness.
