Brislemouths that consume fish prey are found in individuals ranging from 70 mm to 75 mm. [5] Bristlemouths do not have seasonal trends when it comes to their feeding habits. Bristlemouths are diel vertical migrators , therefore migrating closer to the surface waters in the nighttime in order to find more food. [ 3 ]
Populations of large predatory fish in the global oceans were estimated to be about 10% of their pre-industrial levels by 2003, [1] and they are most at risk of extinction; there was a disproportionate level of large predatory fish extinctions during the Cretaceous–Paleogene extinction event 66 million years ago.

Various carnivorans, with feliforms to the left, and caniforms to the right. Carnivora is an order of placental mammals that have specialized in primarily eating flesh. Members of this order are called carnivorans, or colloquially carnivores, though the term more properly refers to any meat-eating organisms, and some carnivoran species are omnivores or herbivores.
A piscivore (/ ˈ p ɪ s ɪ v ɔːr /) is a carnivorous animal that primarily eats fish. The name piscivore is derived from Latin piscis 'fish' and vorō 'to devour'. Piscivore is equivalent to the Greek-derived word ichthyophage, both of which mean "fish eater".
A molluscivore is a carnivorous animal that specialises in feeding on molluscs such as gastropods, bivalves, brachiopods and cephalopods.Known molluscivores include numerous predatory (and often cannibalistic) molluscs, (e.g.octopuses, murexes, decollate snails and oyster drills), arthropods such as crabs and firefly larvae, and, vertebrates such as fish, birds and mammals.

Some snappers grow up to about 1 m (3.3 ft) in length, and one specific snapper, the cubera snapper, grows up to 1.52 m (5 ft 0 in) in length. [2] Most are active carnivores, feeding on crustaceans or other fish, [3] though a few are plankton-feeders. They can be kept in aquaria, but mostly grow too fast to be popular aquarium fish. Most ...
Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million in total. Animals range in size from 8.5 millionths of a metre to 33.6 metres (110 ft) long and have complex interactions with each other and their environments, forming intricate food webs .
Fishes of the World is a standard reference for the systematics of fishes.It was first written in 1976 by the American ichthyologist Joseph S. Nelson (1937–2011). Now in its fifth edition (2016), the work is a comprehensive overview of the diversity and classification of the 30,000-plus fish species known to science.
