Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually).
Hyperpredation, also known as hypopredation, is when a generalist predator increases its predation pressure as a result of the introduction of a substitute prey. [1] Hyperpredation has been proven, for instance, in lab settings using two hosts and a parasitoid wasp. [2] Prey that require more handling time than they are worth in terms of ...
In the context of ecology, predation is considered to play a crucial and necessary role in ecosystems. [47] This has led some writers, such as Michael Pollan, to reject predation as being a moral problem at all, stating "predation is not a matter of morality or politics; it, also, is a matter of symbiosis". [48]

Predators need not locate their host directly: Kestrels, for instance, are able to detect the faeces and urine of their prey (which reflect ultraviolet), allowing them to identify areas where there are large numbers of voles, for example. This adaptation is essential in prey detection, as voles are quick to hide from such predators.
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.
Ambush predators usually remain motionless (sometimes hidden) and wait for prey to come within ambush distance before pouncing. Ambush predators are often camouflaged, and may be solitary. Pursuit predation becomes a better strategy than ambush predation when the predator is faster than the prey. [2] Ambush predators use many intermediate ...
