Bats use private and social information as they hunt

In the arms race between predators and prey, each evolves more and more sophisticated ways of catching or escaping from the other. Rachel Page, staff scientist at the Smithsonian Tropical Research Institute and Ximena Bernal, ...

Possums bounce back from Devils on Maria Island

The recent introduction of healthy Tasmanian Devils to Maria Island was initially bad news for the local possum population, a species blissfully ignorant of the predator's existence.

It's all a blur—why stripes hide moving prey

Scientists at Newcastle University have shown that patterns—particularly stripes which are easy to spot when an animal is still—can also help conceal speeding prey.

Bats use leaves as mirrors to find prey in the dark

On moonless nights in a tropical forest, bats slice through the inky darkness, snatching up insects resting silently on leaves—a seemingly impossible feat. New experiments at the Smithsonian Tropical Research Institute ...

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 the prey. The other main category of consumption is detritivory, the consumption of dead organic material (detritus). It can at times be difficult to separate the two feeding behaviors, for example where parasitic species prey on a host organism and then lay their eggs on it for their offspring to feed on its decaying corpse. The key characteristic of predation however is the predator's direct impact on the prey population. On the other hand, detritivores simply eat what is available and have no direct impact on the "donor" organism(s).

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