Mimicry

In evolutionary biology, mimicry is a similarity of one species to another that protects one or both. In the case of prey species, it is a class of antipredator adaptation. This similarity can be in appearance, behaviour, sound or scent. Mimics occur in the same areas as their models.

Mimicry occurs when a group of organisms, the mimics, evolve to share perceived characteristics with another group, the models. The evolution is driven by the selective action of a signal-receiver or dupe. Birds, for example, use sight to identify palatable insects (the mimics), whilst avoiding the noxious models.

The model is usually another species, except in cases of automimicry. The deceived signal-receiver is typically another organism, such as the common predator of two species. As an interaction, mimicry is in most cases advantageous to the mimic and harmful to the receiver, but may increase, reduce or have no effect on the fitness of the model depending on the situation. The model may be hard to identify: for example, eye spots may not resemble any specific organism's eyes, and camouflage often cannot be attributed to a particular model.

Mimic (Dungeons & Dragons)

In the Dungeons & Dragons fantasy role-playing game, the mimic is a type of fictional monster. It is portrayed as being able to change its shape to disguise its body as an inanimate object, commonly a chest. The mimic has a powerful adhesive that holds fast to creatures who touch the creature, allowing the mimic to beat the creature with its powerful pseudopods. The mimic was introduced in the first edition Advanced Dungeons & Dragons game's original Monster Manual. The mimic subsequently appeared in the game's second edition and third edition. Several variants of the creature have been introduced, with a variety of abilities and sizes.

Publication history

Advanced Dungeons & Dragons 1st edition (1977-1988)

The mimic made its first appearance in the original Monster Manual (1977), by Gary Gygax. This book described mimics as "subterranean creatures which cannot stand the light of the sun. They are able to perfectly mimic stone or wood." According to the book, mimics thus pose as items such as stonework, doors, or chests; when a character or creature touches the disguised mimic, the mimic can lash out with a bludgeoning pseudopod. A mimic excretes an adhesive glue to hold fast whatever touches it. The book states that all mimics move about constantly in search of prey. Mimics are described as neutral in alignment.

Hypolimnas misippus

The Danaid Eggfly, Mimic, or Diadem (Hypolimnas misippus) is a widespread species of nymphalid butterfly. It is well known for polymorphism and mimicry. Males are blackish with distinctive white spots that are fringed in blue. Females are in multiple forms that include male like forms while others closely resemble the toxic butterflies Danaus chrysippus and Danaus plexippus. They are found across Africa, Asia, and Australia.

Description

The male has the upperwings dark velvety brownish-black. The forewing has a broad white oval spot between the veins 3 and 7. A smaller spot near the apex is also present. These spots are crossed by the black veins and bordered in iridescent blue that is visible only at certain angles. The hind wing has a larger white spot but the veins crossing it are yellowish and not as prominent as on the forewing. There are some white specks along the tornus and the margin is edged with white and black.

Mimic (film)

Mimic is an American 1997 science fiction horror film co-written and directed by Guillermo del Toro, and starring Mira Sorvino, Jeremy Northam, Josh Brolin, Charles S. Dutton and Giancarlo Giannini. It is based on a short story of the same name by Donald A. Wollheim.

Del Toro was unhappy with the film as released, especially because he did not succeed in obtaining a final cut of the film; however, his director's cut version was finally released in 2011. Mimic, whose U.S. theatrical gross was $25 million, was followed by two direct-to-video sequels, Mimic 2 (2001) and Mimic 3: Sentinel (2003), neither of them with del Toro involved.

It includes several examples of del Toro's most characteristic hallmarks. "I have a sort of a fetish for insects, clockwork, monsters, dark places, and unborn things," said del Toro, and this is evident in Mimic, where at times all are combined in long, brooding shots of dark, cluttered, muddy chaotic spaces. According to Alfonso Cuarón, del Toro's friend and colleague, "with Guillermo the shots are almost mathematical — everything is planned.”

Mimic (comics)

Mimic (Calvin Montgomery Rankin) is a fictional character appearing in comic books published by Marvel Comics. He was briefly a member of the X-Men in the 1960s, and was the first character to be added to the team after the original line-up and the first X-Man who was not a mutant.

An alternate reality version of Mimic became a popular member of the Exiles, the reality-hopping team.

Fictional character biography

Origins

Calvin Rankin was born in Passaic, New Jersey. After an accidental mixup of chemicals from his father Ronald's experiments, he gained the ability to temporarily copy the skills, physical traits, knowledge, and superpowers of any person within close range (approximately ten feet), which led people to fear him. When his father found out about this, he retreated with Calvin into a mine where he worked on a machine which, as he claimed, would make the abilities his son absorbed permanent. However, his experiments with the device caused several power outages in the vicinity; in order to hold off the mob which was tracking these disturbances, Ronald Rankin blasted the mine entrance, but he was accidentally caught and killed in the explosion, and his device sealed deep inside the mine.
