Inter-sexual mimicry (a type of automimicry, as it is within a single species) occurs when individuals of one sex in a species mimic members of the opposite sex to facilitate sneak mating. An example is the three male forms of the marine isopod Paracerceis sculpta. Alpha males are the largest and guard a harem of females. Beta males mimic ...
Batesian mimicry is a form of mimicry where a harmless species has evolved to imitate the warning signals of a harmful species directed at a predator of them both. It is named after the English naturalist Henry Walter Bates , who worked on butterflies in the rainforests of Brazil.
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 ...
Examples include many moth, butterfly, and fish species that have "eye-spots". These are large dark markings that help prey escape by causing predators to attack a false target. For example, the gray hairstreak (Strymon melinus) shows the false head at its rear; it has a better chance of surviving an attack to that part than an attack to the head.
Mimicry is an adaptation by a species, called the mimic, making it resemble something else, called the model, with the effect of deceiving another species, the dupe. The three are not always all distinct, as mimicry can for example be within a species. [3] The adaptation is to the evolutionary advantage of the mimic.
The walking leaf insects from the Indo-Pacific region resemble tree leaves in appearance and posture.In biology, mimesis (from ancient Greek μίμησις mímēsis, "imitation") [1] is a form of crypsis where living creatures mimic the form, colour and posture of their surroundings to avoid being noticed from their surroundings by predators depending on sight. [2]
For example, Batesian mimicry may occur in cheetah cubs. They replicate the appearance of a sympatric species, the honey badger ( Mellivora capensis). The honey badger has a white or silvery back with a black or brownish underbelly and grows to a body length of about three feet long and ten inches high.
Chemical mimicry (or molecular mimicry) is a type of biological mimicry involving the use of chemicals to dupe an operator. A chemical mimic dupes an operator (e.g. a predator) by showing an adaptive chemical resemblance to an object of its environment and as a consequence receives selective advantage. [ 1 ]
