Seal whiskers, the secret weapon for hunting

The deep ocean is a dark place, yet deep-diving seals can easily locate their prey in that darkness. A multi-national research team has used field-based studies to better understand how seals use their whiskers in their search ...

The answer to keeping moose populations healthy? Wolves

Predators may keep prey populations healthy by acting as a selective force against genetic diseases. A new study found that wolves select adult moose based on age and osteoarthritis, a chronic disease that can be influenced ...

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.
