One behavioural adaptation that the organism displays and why it might behave this way in order to be successful?

An African Porcupine acts very fast when predators are around. They rattle when shaken, serving as a warning to potential predators. If that doesn't work, the predator may attempt to charge backwards at its predators. That's one of the behavioural adaptation that an African Porcupine displays when predators try to kill them.
