Apparent death is an antipredator behavior observed in a wide range of animals in which they take on the appearance of being dead to an observer. This could either be an involuntary reflex action, as in tonic immobility; or an adaptive behavior as in thanatosis, which is used both as a defense mechanism and as a form of aggressive mimicry.
