An apex predator, also known as a top predator or superpredator, is a predator [a] at the top of a food chain, without natural predators of its own. [6][7] Apex predators are usually defined in terms of trophic dynamics, meaning that they occupy the highest trophic levels.

Predatory fish. A barracuda preying on a smaller fish. Predatory fish are hypercarnivorous fish that actively prey upon other fish or aquatic animals, with examples including shark, billfish, barracuda, pike / muskellunge, tuna, dolphinfish, walleye, perch and salmon. Some omnivorous fish, such as the red-bellied piranha, can occasionally also ...
In the ocean food chain, large sharks generally only have to worry about keeping orcas at bay — but a new study suggests the apex predators may have to watch out for their own.. Researchers have ...
The giant otter is an apex predator, and its population status reflects the overall health of riverine ecosystems. [57] It feeds mainly on fish, including cichlids, perch, characins (such as piranha), and catfish. [58] One full-year study of giant otter scats in Amazonian Brazil found fish present in all fecal samples.
Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. Some keystone species, such as the wolf and lion, are also apex predators. The role that a keystone species plays in its ecosystem is analogous to the role of a keystone in an arch. While the keystone is under the least pressure of any of the ...
The giant trevally is an apex predator in most of its habitats, and is known to hunt individually and in schools. The species predominantly takes various fish as prey, although crustaceans, cephalopods, and molluscs make up a considerable part of their diets in some regions.
Orcas are apex predators with a diverse diet. Individual populations often specialize in particular types of prey. This includes a variety of fish, sharks, rays, and marine mammals such as seals and other dolphins and whales. They are highly social; some populations are composed of highly stable matrilineal family groups (pods).
