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.

Batomorphi is a clade of cartilaginous fishes, commonly known as rays, this taxon is also known as the superorder Batoidea, but the 5th edition of Fishes of the World classifies it as the division Batomorphi. [2]

These delightful little angelfish are highly prized as aquarium fish, with an exorbitant price tag beyond the realms of most aquarists. A single fish has sold for $30,000.
Unlike those carnivorous fish, tilapia can feed on algae or any plant-based food. This reduces the cost of tilapia farming, reduces fishing pressure on prey species, avoids concentrating toxins that accumulate at higher levels of the food chain , and makes tilapia the preferred "aquatic chickens" of the trade.
Sea anemones and their attendant anemone fish can make attractive aquarium exhibits, and both are often harvested from the wild as adults or juveniles. [39] These fishing activities significantly impact the populations of anemones and anemone fish by drastically reducing the densities of each in exploited areas. [ 39 ]
Top row: unaffected fish; bottom row: fish preyed upon by the carnivorous alga Pfiesteria shumwayae. Predatory dinoflagellates are predatory heterotrophic or mixotrophic alveolates that derive some or most of their nutrients from digesting other organisms. About one half of dinoflagellates lack photosynthetic pigments and specialize in ...
Spotted oceanic triggerfish display plasticity in their eating habits, being considered either a carnivorous or a planktivorous fish. Upon examination, they consume smaller fish, Halobates (sea skaters), members of the order “Siphonophores,” and smaller cartilaginous fish (Senta et al., 1993).
