The assumption of scarcity in vertebrate mimetic resemblances is largely limited due to human perception. Humans are hyper-perceptive to visual mimicry systems, and find these the most abundant. However, olfactory, biochemical, and even electroreceptive forms of mimicry are likely to be much more common than currently accounted for. [1] [30] [31]
Batesian mimicry stands in contrast to other forms such as aggressive mimicry, where the mimic profits from interactions with the signal receiver. One such case of this is in fireflies , where females of one species mimic the mating signals of another species, deceiving males to come close enough for them to eat.
Mimicry is an evolved resemblance between an organism and another object, often an organism of another species. Mimicry may evolve between different species, or between individuals of the same species. Often, mimicry functions to protect from predators. [11] Mimicry systems have three basic roles: a mimic, a model, and a dupe.
Some harmless milk snake (Lampropeltis triangulum) subspecies, the moderately toxic false coral snakes (genus Erythrolamprus), and the deadly coral snakes (genus Micrurus) all have a red background color with black and either white or yellow rings. Over 115 species or some 18% of snakes in the New World are within this mimicry system. [10]
Aggressive mimicry stands in semantic contrast with defensive mimicry, where it is the prey that acts as a mimic, with predators being duped. Defensive mimicry includes the well-known Batesian and Müllerian forms of mimicry, where the mimic shares outward characteristics with an aposematic or harmful model. In Batesian mimicry, the mimic is ...
Most of these octopuses use Batesian mimicry, selecting an organism repulsive to predators as a model. [33] [34] In Müllerian mimicry, two or more aposematic forms share the same warning signals, [27] [35] as in viceroy and monarch butterflies. Birds avoid eating both species because their wing patterns honestly signal their unpleasant taste. [28]
Deception in animals is the voluntary or involuntary transmission of misinformation by one animal to another, of the same or different species, in a way that misleads the other animal. The psychology scholar Robert Mitchell identifies four levels of deception in animals.
The mechanism is found in both vertebrates such as fishes and snakes, and insects such as hairstreak butterflies. Automimicry has sometimes been put to military use. The A-10 Thunderbolt (Warthog) was often painted with a false canopy on its underside, imitating itself, while the armoured recovery vehicle variant of the Churchill tank had a ...
