Lanternfish typically have a slender, compressed body covered in small, silvery deciduous cycloid scales (ctenoid in four species), a large bluntly rounded head, large elliptical to round lateral eyes (dorsolateral in Protomyctophum species), and a large terminal mouth with jaws closely set with rows of small teeth.
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 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 ...
Lanternfish account for as much as 65 percent of all deep sea fish biomass and are largely responsible for the deep scattering layer of the world's oceans.. The phantom bottom is caused by the sonar misinterpreting as the ocean floor a layer of small seagoing creatures that congregate between 1,000 and 1,500 feet (300 and 460 m) below the surface.
Narcissists tend to be excluded in social circles because of their disruptive behaviors, and if they feel left out, their arrogant and aggressive behaviors will only intensify, a new study ...
Abyssal (or submarine) fans are formed from turbidity currents. These currents begin when a geologic activity pushes sediments over the edge of a continental shelf and down the continental slope, creating an underwater landslide. A dense slurry of muds and sands speeds towards the foot of the slope, until the current slows. The decreasing ...
[11] [12] [13] [7] The integration of subsurface datasets such as 3D/4D seismic reflection, well logs, and core data as well as modern seafloor bathymetry studies, numerical forward stratigraphic modeling, and flume tank experiments are enabling improvements and more realistic development of submarine fan models across different basins.
Sharks portal; The blackbelly lanternshark or lucifer shark (Etmopterus lucifer) is a shark of the family Etmopteridae found around the world in tropical and temperate seas at depths between 150 and 1,250 meters – the mesopelagic zone. [2]
