Hedgehogs are generally nocturnal. Although their eyesight is weak, other senses that help them to forage at night are more developed. Hedgehogs rely upon their strong senses of hearing and smell. The hedgehog's protruding snout is very sensitive and mobile, allowing it to search for prey through undergrowth. Hedgehogs usually forage for food, such as insects and vegetation, at night when it is more difficult for predators to see them. While sleeping during the day, these animals protect themselves from predators by assuming the curled-up position.
