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]
However, this form of mimicry is prevalent in snakes and frogs, where chemical defense has coevolved with distinct coloration. Still, mammals have evolved Batesian mimicry systems where particularly powerful or harmful models exist. A venomous coral snake and some of its multiple nonvenomous mimic species
Müllerian mimicry was first identified in tropical butterflies that shared colourful wing patterns, but it is found in many groups of insects such as bumblebees, and other animals such as poison frogs and coral snakes. The mimicry need not be visual; for example, many snakes share auditory warning signals. Similarly, the defences involved are ...
For example, when predators avoid a mimic that imperfectly resembles a coral snake, the mimic is sufficiently protected. [ 26 ] [ 27 ] [ 28 ] Convergent evolution is an alternative explanation for why coral reef fish have come to resemble each other; [ 29 ] [ 30 ] the same applies to benthic marine invertebrates such as sponges and nudibranchs .
Batesian mimicry is a case of protective or defensive mimicry, where the mimic does best by avoiding confrontations with the signal receiver. It is a disjunct system, which means that all three parties are from different species. [ 11 ]
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 ...
Similarly, some snakes employ caudal luring (using the tail) [14] [15] or lingual luring (using the tongue) to entice small vertebrates into striking range. [16] [17] Argiope argentata and its web. Aggressive mimicry is common amongst spiders, both in luring prey and stealthily approaching predators. [18]
Rhinobothryum bovallii, commonly known as the coral mimic snake or the false tree coral, is a species of snake in the family Colubridae. The species is native to Central America and northwestern South America .
