Known to be one of the largest invertebrate predators in the deep sea, the giant phantom jellyfish's typical prey consists of plankton and small fish. The S. gigantea tends to be more dominant in locations with a low productivity system, which in turn deters other predatory organisms, like fish, to high productivity systems (coastal, upwelling ...
Dunkleosteus is an extinct genus of large arthrodire ("jointed-neck") fish that existed during the Late Devonian period, about 382–358 million years ago.It was a pelagic fish inhabiting open waters, and one of the first vertebrate apex predators of any ecosystem.

[10] [11] It is known to inhabit the circumantarctic Southern Ocean. [3] It is presumed to be an ambush predator, and is likely a key prey item of the sperm whale. [12] [13] The first specimens were discovered and described in 1925. [14] In 1981, an adult specimen was discovered; in 2003, a second specimen was collected.
Adults feed in a predator-prey relationship almost exclusively on the sea butterflies of the genus Limacina: on Limacina helicina and on Limacina retroversa. [3] [8] The feeding process of Clione limacina is somewhat extraordinary. The buccal ("mouth") apparatus consists of three pairs of buccal cones. These tentacles grab the shell of Limacina ...
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 at or above 1,000 metres (3,300 ft) below the surface of the water.
