Aposematism is the advertising by an animal, whether terrestrial or marine, to potential predators that it is not worth attacking or eating. [1] This unprofitability may consist of any defenses which make the prey difficult to kill and eat, such as toxicity, venom, foul taste or smell, sharp spines, or aggressive nature.

Aposematism, biological means by which a dangerous, or noxious, organism advertises its dangerous nature to a potential predator. The predator, having recognized the dangerous organism as an unfavorable prey, thereupon desists from attacking it. Learn more about aposematism in this article.

2008年6月16日 · The meaning of APOSEMATISM is the use of a signal and especially a visual signal of conspicuous markings or bright colors by an animal to warn predators that it is toxic or distasteful : warning coloration. How to use aposematism in a sentence.

2018年6月21日 · Aposematism is a well-studied topic within evolutionary biology, and aposematic signals have been found in many species across the animal kingdom. Extensive research has also been conducted documenting both learned and naïve predator responses to …

2015年5月4日 · What is aposematism? The word comes from the Greek απο (away) and σεμα (sign) and describes a strategy whereby animals warn predators about their unprofitability. It consists of two elements: a primary defence, such as distinctive colours, odours or sounds, that operates before the predator attacks; and a secondary defence, be it ...

The evolution of aposematism is considered to be a major evolutionary problem because if new aposematic forms emerged in defended cryptic populations, they would face the dual problems of rarity and conspicuousness. We argue that this commonly assumed …

2022年2月2日 · Aposematism is a mechanism by which an animal prevents an attack by its predators by signaling them to stay away. This signal is an alternative to fighting for self-defense, fleeing or camouflage. Aposematism can take different forms.

Aposematism (Greek, apo = away, sematic = sign) is the use of warning coloration to inform potential predators that an animal is poisonous, venomous, or otherwise dangerous. From: Animal Behavior (Second Edition), 2016

2017年5月8日 · Understand the concept of aposematism, where bright coloration in animals serves as a warning to predators about their toxicity or unpalatability.

2019年4月23日 · Dividing defences into these categories gives surprising new insights into the evolution of aposematism. We collate examples of defences from both invertebrates and vertebrates that are morphological, and hence obvious, or physiological and behavioural and that are hidden, and show how they are situated at different stages of the predator ...
