Many groupers are important food fish; some are now farmed. Unlike most other fish species, which are chilled or frozen, groupers are usually sold alive in markets. [26] Many species are popular game fish for sea-angling. Some species are small enough to be kept in aquaria, though even the small species are inclined to grow rapidly. [citation ...
The giant grouper has a wide Indo-Pacific distribution, it is the most widely distributed species of grouper in the world. [5] It occurs from the Red Sea and the eastern coasts of Africa as far south as Algoa Bay in South Africa and across the Indian Ocean into the Western Pacific Ocean as far east as the Pitcairn Islands and Hawaii.
A Nassau grouper, E. striatus, ambushes its prey on Caribbean coral reefs. The Nassau grouper is a medium to large fish, growing to over a meter in length and up to 25 kg in weight. It has a thick body and large mouth, which it uses to "inhale" prey. Its color varies depending on an individual fish's circumstances and environment.
The relative use of ram and suction feeding is species dependent, but it can help determine the accuracy of prey capture. [18] The mouth aperture represents another tradeoff between the ability to capture large elusive prey with more chances of failure—large gape—or to capture smaller elusive prey with greater success—smaller gape.
The Atlantic goliath grouper was historically referred to as the "jewfish", and there are several theories as to the name's origin. A 1996 review of the term's history from its first recorded usage in 1697 concluded that the species' physical characteristics were frequently connected to "mainstay caricatures of anti-Semitic beliefs", whereas the interpretation that the fish was regarded as ...
Gulf groupers at a young age tend to prey on different types of fish and invertebrates such as crabs and shrimp. As Gulf Groupers mature, they tend to primarily prey on different fish species. Mature adults tend to hunt during dawn and dusk when the sun is not too bright on the water.
An Octopus cyanea hunts with a blacktip grouper on one side and a blue goatfish on the other. ... The researchers did not see evidence that the creatures shared prey. All the species involved are ...
The family contains about 450 species in 65 genera, including the sea basses and the groupers (subfamily Epinephelinae). Although many species are small, in some cases less than 10 cm (3.9 in), the giant grouper ( Epinephelus lanceolatus ) is one of the largest bony fishes in the world, growing to 2.7 m (8 ft 10 in) in length and 400 kg (880 lb ...
