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 .
Tertiary consumers, which are sometimes also known as apex predators, are hypercarnivorous or omnivorous animals usually at the top of food chains, capable of feeding on both secondary consumers and primary consumers. Tertiary consumers are usually the largest, strongest and most aggressive animal in the local environment.
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.
Without apex predators, there is a decreased level of inter-specific competition in the food chain between mesocarnivores, allowing them to increase their scavenging options for different food. [11] As mesocarnivores are scavengers, they will eat any food that is accessible to them.

“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 ...
Shocked researchers are trying to figure out what kind of apex predator took out an 8-foot-shark as it wandered through the oceans — and they think it might have been another, bigger shark.
Apex predators reduce mesopredator populations and change mesopredator behaviors and habitat choices by preying on and intimidating mesopredators. [6] When apex predator populations decline, mesopredators can access hunting and den areas once controlled by the apex predators, essentially assuming the role of an apex predator. [2]
