Apex predator

Apex predators (also alpha predators, superpredators, or top-level predators) are predators that, as adults, are not normally preyed upon in the wild in significant parts of their ranges. An animal can be a superpredator in some environments but not in others (e.g., the domestic cat). Some species are at the end of long food chains, where they have a crucial role in maintaining and determining the health of ecosystems, and some predators are at the end of a food chain having only three stages (grass→deer→wolf), the bare minimum for inclusion. Some, like  big cats, bears, hyenas, crocodiles, wolves and large dogs, some sharks, the Komodo dragon, and the orca, are potential man-eaters, although most of them will avoid humans. Even those not dangerous to humans (e.g., owls) are formidable predators in their niches.
