Etymology
apo- (prefix meaning ‘away from’) (from Ancient Greek ᾰ̓πό (ăpó, “from, away from”)) + semat(ic) (“acting as a sign of danger”) (from Ancient Greek σῆμα (sêma, “mark, sign, token”), from Proto-Indo-European *dʰyeh₂- (“to notice”) + -μᾰ (-mă, suffix forming neuter nouns denoting the object or result of an action, or a particular instance of an action)) + -ism. The word aposematic was coined by British evolutionary biologist Edward Bagnall Poulton (1856–1943) in The Colours of Animals (1890).
Meanings
-
An adaptation, especially a form of coloration, that warns off potential predators.
Detected prey can avoid an attack by way of warning signals (aposematism), for example, bright coloration as a sign of toxicity. […] Aposematisms offer opportunities for 'cheating' species which are not poisonous but show the same color pattern, so-called Batesian mimicry.
2008, J. M. Jeshke, C. Laforsch, R. Tollrian, “Animal Prey Defenses”, in Encyclopedia of Ecology, volumes 1 (A–C), Amsterdam: Elsevier, →ISBN, page 191, column 2:First, the selection of "red" as a releaser in courtship and social chasing indicates a secondarily evolved use of aposematic coloring. It is assumed here that aposematism in this and other red-and-black heliconiids, and their correlated development of Müllerian mimicry, occurred in evolution before the development of red as a social releaser.
1954, Zoologica: Scientific Contributions of the New York Zoological Society, New York, N.Y.: New York Zoological Society, →OCLC, page 193, column 1:For example, both toxicity and coloration may be energetically costly to produce and maintain, and some theoretical models have predicted that once a predator has learned that a prey is toxic, prey should reduce the amount of energy invested in producing an honest signal. This could in turn make aposematism evolutionarily stable, as opposed to a constant arms race between toxicity, coloration and predator perception or toxic resistance

Aposematism has thus been variously proposed in plants […] where, for example, conspicuous coloration on the tips of defensitve spines might serve to draw the attention of predators and deter them from attacking. It has been suggested also that aposematism exists in some fungi […]
