 Displays are classified as deimatic or aposematic by the responses of the animals that see them . Where predators are initially startled but learn to eat the displaying prey , the display is classed as deimatic , and the prey is bluffing ; where they continue to avoid the prey after tasting it , the display is taken as aposematic , meaning the prey is genuinely distasteful . However , these categories are not entirely mutually exclusive . It is possible for a behaviour to be both deimatic and aposematic , if it both startles a predator and indicates the presence of antipredator adaptations .
