Solitary predator: a polar bear feeds on a bearded seal it has killed. Social predators: meat ants cooperate to feed on a cicada far larger than themselves.. Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey.
An example, which has caused much trouble in Maryland and Florida, is the snakehead fish. [ 5 ] Predatory fish such as sharks , billfish , dolphinfish and tuna form a part of the human diet and are targeted by fisheries , but they tend to concentrate significant quantities of mercury in their bodies because they are high in the food chain ...

For example, the hemipteran Arachnocoris berytoides resembles Faiditus caudatus, a spider commensal of ants. [34] In cryptic aggressive mimicry, the predator mimics an organism that its prey is indifferent to. This allows the predator to avoid detection until the prey are close enough for the predator to strike, effectively a form of camouflage.
Predation risk has long been recognized as critical in shaping behavioral decisions. For example, this predation risk is of prime importance in determining the time of evening emergence in echolocating bats. Although early access during brighter times permits easier foraging, it also leads to a higher predation risk from bat hawks and bat falcons.
Raccoons and skunks are common examples of mesopredators. Pictured is a common raccoon and a striped skunk eating cat food in an urban area.. A mesopredator is a predator that occupies a mid-ranking trophic level in a food web. [1]
Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, [4] ornithologists typically use the narrower definition followed in this page, [5] excluding many piscivorous predators such as storks, cranes, herons, gulls, skuas, penguins, and kingfishers, as well as many primarily ...
A stoat surplus killing chipmunks (Ernest Thompson Seton, 1909) Multiple sheep killed by a cougar. Surplus killing, also known as excessive killing, henhouse syndrome, [1] [2] or overkill, [3] is a common behavior exhibited by predators, in which they kill more prey than they can immediately eat and then they either cache or abandon the remainder.
