Spanish red deer in El Pardo. European bison in San Cebrián de Mudá. Male Iberian ibex Pyrenean chamois. The even-toed ungulates are ungulates whose weight is borne about equally by the third and fourth toes, rather than mostly or entirely by the third as in perissodactyls. There are about 220 artiodactyl species, including many that are of ...
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 .
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 ...
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.
A red fox (Vulpes vulpes) eating a rodent—an example of a mesocarnivoreNot to be confused with mesopredator A mesocarnivore is an animal whose diet consists of 30–70% meat with the balance consisting of non-vertebrate foods which may include insects, fungi, fruits, other plant material and any food that is available to them.

Healthy, free-flying Spanish imperial eagles are apex predators, being mostly free of natural predators themselves but they do sometimes kill each other in conflicts and rarely interspecies conflicts may too be fatal. When protected from human persecution and far from threats such as powerlines, adult mortality can be as low as 3–5.4% annually.
The golden dorado is the apex predator in its freshwater habitat. [6] They are primarily piscivores , eating a wide variety of fish, but have also been recorded feeding on large insects, crustaceans and small vertebrates (for example, rodents , lizards and birds).
