Apex predators (also alpha predators or superpredators) are predators that are not preyed upon in the wild. These species are often at the end of long food chains, where they have a crucial role in maintaining and determining the health of ecosystems. Even if not dangerous to humans, they are formidable predators in their respective niches. Apex predators often have a special place in human culture and they have come to represent aspects of nature that humans find important and often appear in heraldry. The eagle ...

The Paleocene epoch (65-56 MYA) ("early dawn of the recent") is the first geologic epoch of the Palaeogene period in the modern Cenozoic era. As with most other older geologic periods, the strata that define the epoch's beginning and end are well identified, but the exact date of the end is uncertain. The Paleocene epoch immediately followed the mass extinction event at the end of the Cretaceous, known as the K-T boundary (Cretaceous - Tertiary), which marks the demise of the dinosaurs. The die-off of the dinosaurs left unfille ...

Conservation status: Lower risk (cd) The Polar Bear (Ursus maritimus), also known as White Bear or Northern Bear, is a large bear native to the Arctic. It is the largest land carnivore species. It is the apex predator within its range. It is well-adapted to its habitat: its thick blubber and fur insulate it against the cold, its white color camouflages it from its prey, and it hunts well both on land and in the water.

Many mammals are found at the site. All are small compared to modern mammals, the largest being sheep-sized. Preserved mammals include a squirrel-like primitive primate and Ptilodus; an arboreal multituberculate. The largest mammal at the site is the condylarth herbivore Phenacodus. An additional mammal fossil is Protictis, a weasel sized member of Viverridae that may have hunted on the forest floor. Reptiles are the dominate animal type preserved at Wannagan. The largest animal (~4 m in length) found at the site ...

Contrary to conventional belief, predation is not typically an indiscriminate urge to kill other living beings. When hunger is not an issue for the animal, most predators will typically not seek to attack prey since the basic need is absent and it is a waste of energy to do so. For instance, a large predator fish like a shark that is well fed in an aquarium will typically ignore the smaller fish swimming around it (while the prey fish take advantage of the fact t ...
