The rough abyssal grenadier (Coryphaenoides yaquinae) is a species of deep-sea grenadier fish in the family Macrouridae. First described as a separate species in 1974, the rough abyssal grenadier was historically confused with its congener , Coryphaenoides armatus . [ 1 ]
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 ...

[2] The markers are commonly (and erroneously) believed to have been used to aid camera calibration for the US Central Intelligence Agency 's Corona spy satellite program; [ 3 ] in fact, they were used as ...
Environments in which subsurface life has been found [1]. The deep biosphere is the part of the biosphere that resides below the first few meters of the ocean's surface. It extends 10 kilometers below the continental surface and 21 kilometers below the sea surface, at temperatures that may reach beyond 120 °C (248 °F) [2] which is comparable to the maximum temperature where a metabolically ...
