Give your example of the adaptability of animals to get food or to defend against enemies.

Example: A hedgehog, defending himself, is able to curl up into a ball bristling with needles. Not every predator is able to overcome this obstacle and get to its prey. Needles are the hedgehog’s only defense. After all, this animal does not know how to run fast or climb a tree. Faced with danger, the hedgehog turns into a tight ball with spiky needles, begins to hiss and jump. So most predators, who do not have sharp fangs and long claws, prefer not to mess with the hedgehog.
