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]
The brightly colored, ringed patterns of snakes of the genus Erythrolamprus resemble those of sympatric coral snakes of the genus Micrurus, and it has been suggested that this is due to mimicry. Whether this is classical Batesian mimicry, classical Müllerian mimicry, a modified form of Müllerian mimicry, or no mimicry at all, remains to be ...
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.
Batesian mimicry is a form of defense that allows a harmless species to mimic the appearance of a toxic, noxious, or harmful species to protect itself from predators. By mimicking the appearance of a harmful species, a predator is less likely to attack the species due to its awareness of the signal of warning color patterns.
This type of deception seems to be prevalent in humans, [3] but this level also corresponds to the realization of higher-order intentionality. [4] Tactical or functional deception is the use of signals or displays from an animal's normal repertoire to mislead or deceive another individual. [25]
The snake marks the third animal species named after Ford. He also inspired the name of an ant, called Pheidole harrisonfordi, and a spider, Caledonia harrisonfordi. (Getty)

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 ...
