All the behavioural patterns that preserve animals from environmental challenges should be included in this chapter. Many of these, however, have already been described in the preceding chapter. Therefore, only the ethological mechanisms which maximize protection from predators will be treated. This can be achieved by several strategies, in which morphological and behavioural features concur. Various expressions have been employed by students of animal behaviour to describe them. Not surprisingly, therefore, a certain confusion of terms exists. Expressions such mimicry, protective resemblance, camouflage, masking, homochromy, concealment, crypsis, adaptive colouration, protective colouration, etc. are not always used correctly (Cloudsley-Thompson 1986). Therefore, I will give my own opinion on this matter.
