Apex predator

For other uses, see Apex predator (disambiguation).

The lion is the world's second-largest big cat and serves as an apex land predator in Africa.[1][2]
The saltwater crocodile is the largest living reptile and the dominant predator throughout its range.[3][4]
The great white shark (bottom) is a known marine apex predator; however, the orca (killer whale, top) is known to be one as well, even towards sharks. Despite coexisting the majority of the time, confrontations may occur in stressed environments when both species compete for limited resources.

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. Food chains are often far shorter on land, usually limited to being secondary consumers – for example, wolves prey mostly upon large herbivores (primary consumers), which eat plants (primary producers). The apex predator concept is applied in wildlife management, conservation, and ecotourism.

Apex predators have a long evolutionary history, dating at least to the Cambrian period when animals such as Anomalocaris and Timorebestia dominated the seas.

Humans have for many centuries interacted with apex predators including the wolf, birds of prey, and cormorants to hunt game animals, birds, and fish respectively. More recently, humans have started interacting with apex predators in new ways. These include interactions via ecotourism, such as with the tiger shark, and through rewilding efforts, such as the proposed reintroduction of the Iberian lynx.
