Antipredator adaptations

To counter predation, prey have evolved defences for use at each stage of an attack. They can try to avoid detection, such as by using camouflage and mimicry. They can detect predators and warn others of their presence. If detected, they can try to avoid being the target of an attack, for example, by signalling that they are toxic or unpalatable, by signalling that a chase would be unprofitable, or by forming groups. If they become a target, they can try to fend off the attack with defences such as armour, quills, unpalatability, or mobbing; and they can often escape an attack in progress by startling the predator, playing dead, shedding body parts such as tails, or simply fleeing.
