As described by Paine in 1966, some sea stars (e.g., Pisaster ochraceus) may prey on sea urchins, mussels, and other shellfish that have no other natural predators. [19] If the sea star is removed from the ecosystem, the mussel population explodes uncontrollably, driving out most other species. [4] These creatures need not be apex predators.
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 .
Livyatan was an apex predator, and probably had a profound impact on the structuring of Miocene marine communities. Using its large and deeply rooted teeth, it is likely to have hunted large prey near the surface, its diet probably consisting mainly of medium-sized baleen whales ranging from 7–10 m (23.0–32.8 ft) in length.

In the other corner – the most ferocious predator to ever emerge from a swampy river – the callous crocodile! Who would reign victorious if these two terrifying apex predators battled in the ring?
When populations of an apex predator decrease, populations of mesopredators in the area often increase due to decreased competition and conflict with the apex predator. [2] This is known as the mesopredator release effect , which refers to the release of mesopredators from the trophic cascade . [ 5 ]
“They are the only group of birds that achieved the role of terrestrial apex predators, evolving species that basically conquered South America during the Miocene (about 23.03 million to 5.33 ...
Piraiba, along with other large amazon catfish species, are important apex predators in the Amazon Basin. This water body serves as a central source for fisheries in South America, providing food for communities in the area. However, this species, along with several other South American catfishes, are declining in population.
