Great white shark diet surprises scientists

The first-ever detailed study of the diets of great white sharks off the east Australian coast reveals this apex predator spends more time feeding close to the seabed than expected.

Is it a bird? Is it a plane? No, it's a squid

A species of oceanic squid can fly more than 30 metres (100 feet) through the air at speeds faster than Usain Bolt if it wants to escape predators, Japanese researchers said Friday.

Research shows jackdaws can recognise individual human faces

When you're prey, being able to spot and assess the threat posed by potential predators is of life-or-death importance. In a paper published today in Animal Behaviour, researchers from the University of Cambridge's Department ...

The strongest animal in the world

The world's strongest animal, the copepod, is barely 1 mm long. It shows that copepods - in relation to their size - are more than 10 times as strong as has been previously documented for any other animal.

Fish mimics octopus that mimics fish

Nature's game of intimidation and imitation comes full circle in the waters of Indonesia, where scientists have recorded for the first time an association between the black-marble jawfish (Stalix cf. histrio) and the mimic ...

Predation

In ecology, predation describes a biological interaction where a predator (an organism that is hunting) feeds on its prey (the organism that is attacked). Predators may or may not kill their prey prior to feeding on them, but the act of predation always results in the death of its prey and the eventual absorption of the prey's tissue through consumption. Other categories of consumption are herbivory (eating parts of plants) and detritivory, the consumption of dead organic material (detritus). All these consumption categories fall under the rubric of consumer-resource systems. It can often be difficult to separate our various types of feeding behaviors. For example, parasitic species prey on a host organism and then lay their eggs on it for their offspring to feed on it while it continues to live or on its decaying corpse after it has died. The key characteristic of predation however is the predator's direct impact on the prey population. On the other hand, detritivores simply eat dead organic material arising from the decay of dead individuals and have no direct impact on the "donor" organism(s).

Selective pressures imposed on one another often leads to an evolutionary arms race between prey and predator, resulting in various antipredator adaptations.

The unifying theme in all classifications of predation is the predator lowering the fitness of its prey, or put another way, it reduces its prey's chances of survival, reproduction, or both. Ways of classifying predation surveyed here include grouping by trophic level or diet, by specialization, and by the nature of the predator's interaction with prey.
