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.
Examples are chosen from mammals, insects, reptiles and marine animals, and empirical evidence from feeding experiments with toads is presented. Part 3, disguise, covers methods of mimicry that provide camouflage, as when animals resemble leaves or twigs, and markings and displays that help to deflect attack or to deceive predators with ...
