Give a general explanation and two examples. This word implies that the answer to the question involves some sort of mechanistic explanation. That said, the general explanation should relate antipredator behavior to the sensory mechanism used by the predator to search for prey. For example, some antipredator behaviors, such as crypsis, are effective against predators that hunt using visual cues. These behaviors would not be effective against predators that hunt using some other sensory mechanism, such as ultrasound.
Moths use cryptic coloration to hide from birds.
Many predators attack the head of the prey in order to kill it quickly, so many prey have patterns or structures that make some posterior or distal part of the body look like the head, to misdirect attack. This takes advantage of the visual system of the predator. Hairstreaks and other butterflies have eyespots and false antennae on the wing margins. Some snakes and lizards have false heads on the ends of their tails or coil up with their head protected and their tail exposed and waving as though it were a head. Many other examples possible.
