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.
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.
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 ...
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 ...
The predatory species mediating indirect interactions between the mimic and the model is variously known as the [signal] receiver, dupe or operator. By parasitising the honest warning signal of the model, the Batesian mimic gains an advantage, without having to go to the expense of arming itself. The model, on the other hand, is disadvantaged ...
The southern giant hornet is an “aggressive predator” that preys on invertebrates such as butterflies, dragonflies, mantids and grasshoppers, as well as other wasps and geckos, the researchers ...
In communal defence, prey groups actively defend themselves by grouping together, and sometimes by attacking or mobbing a predator, rather than allowing themselves to be passive victims of predation. Mobbing is the harassing of a predator by many prey animals. Mobbing is usually done to protect the young in social colonies.
The honey badger's reverse countershading makes it conspicuous, honestly signalling its ability to defend itself through its aggressive temperament and its sharp teeth and claws. Aposematism is the advertising by an animal, whether terrestrial or marine, to potential predators that it is not worth attacking or eating. [ 1 ]
