The distinction between aggressive mimicry and predator camouflage depends on the signal given to the prey, not easily determined. Aggressive mimicry is a form of mimicry in which predators, parasites, or parasitoids share similar signals, using a harmless model, allowing them to avoid being correctly identified by their prey or host.
Aggression can take a variety of forms, which may be expressed physically, or communicated verbally or non-verbally, including: anti-predator aggression, defensive aggression (fear-induced), predatory aggression, dominance aggression, inter-male aggression, resident-intruder aggression, maternal aggression, species-specific aggression, sex ...
Solitary predator: a polar bear feeds on a bearded seal it has killed. Social predators: meat ants cooperate to feed on a cicada far larger than themselves. Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey.
Gilbertian mimicry is bipolar, involving only two species. The potential host (or prey) drives away its parasite (or predator) by mimicking it, the reverse of host-parasite aggressive mimicry. It was coined by Pasteur as a phrase for such rare mimicry systems, [2] and is named after the American ecologist Lawrence E. Gilbert who described it in ...
