Predating definition Local x dating
The wasp larvae feed on the growing host, eventually killing it.Parasitoids make up as much as 10% of all insect species.Many have sharp claws and jaws to grip, kill, and cut up their prey.In ecology, predators are heterotrophic, getting all their energy from other organisms.Predation is a biological interaction where a predator (a hunting animal) kills and eats its prey (the organism that is attacked).Predators are adapted and often highly specialized for hunting, with acute vision, hearing, and sense of smell.When prey have a clumped (uneven) distribution, the optimal strategy for the predator is to be more specialized as the prey are more conspicuous and can be found more quickly.In size-selective predation, predators select prey of a certain size.
Many predators have acute hearing, and some such as echolocating bats hunt exclusively by active or passive use of sound.The transitive sense of moving an event to an earlier point is the proper one for "predate." "Antedate" is the correct term for occurring before something else.These terms are frequently misused even in educated writing.Predators including big cats, birds of prey, and ants share powerful jaws or claws which they use to seize and kill their prey.Some predators such as snakes and fish-eating birds like herons and cormorants swallow their prey whole; snakes can unhinge their jaws to allow them to swallow large prey, while fish-eating birds have long spear-like beaks that they use to stab and grip fast-moving and slippery prey.
Predation 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. Predator and prey adapt to each other in an evolutionary arms race, coevolving under natural selection to develop antipredator adaptations in the prey and adaptations such as stealth and aggressive mimicry that improve hunting efficiency in the predator.
