Much of the communication between predators and prey can be defined as signaling. In some animals, the best way to avoid being preyed upon is an advertisement of danger or unpalatability, or aposematism. Given the effectiveness of this, it is no surprise that many animals employ styles of mimicry to ward off predators. Some predators also use ...
Predation is a short-term interaction, in which the predator, here an osprey, kills and eats its prey. Short-term interactions, including predation and pollination, are extremely important in ecology and evolution. These are short-lived in terms of the duration of a single interaction: a predator kills and eats a prey; a pollinator transfers ...
One type is where the prey confronts its predator and the interaction ends with no feeding. Two competing predators may interact and the larger predator will prey on the smaller. Smaller organisms may prey on larger organisms. Changing population densities may trigger a role reversal. In addition, adult prey may attack juvenile predators. [1]
Coevolution includes many forms of mutualism, host-parasite, and predator-prey relationships between species, as well as competition within or between species. In many cases, the selective pressures drive an evolutionary arms race between the species involved.
Group hunting allows predators to take down larger prey, as well as prey that can outrun the predator but can be caught by an ambush. For example, lionesses (Panthera leo) hunt cooperatively for large prey such as zebra (Equus burchelli) and wildebeest (Connochaetes taurinus), with each lioness adopting particular positions in a formation.

A predator can be defined to differ from a parasitoid in that it has many prey, captured over its lifetime, where a parasitoid's larva has just one, or at least has its food supply provisioned for it on just one occasion. [1] [2] Relation of predation to other feeding strategies. There are other difficult and borderline cases.

Consumer–resource interactions are the core motif of ecological food chains or food webs, [1] and are an umbrella term for a variety of more specialized types of biological species interactions including prey-predator (see predation), host-parasite (see parasitism), plant-herbivore and victim-exploiter systems.
