  3. Inside the needles of hedgehogs are hollow – they are filled only with air.
  4. The bodies of young hedgehogs protect from predators about 3 000 needles, adults – 5-6 thousand needles.
  5. In recent years, more and more hedgehogs are moving from forests to cities. Scientists attribute this to the fact that the main enemies of the hedgehogs, badgers, and owls, are not present in the city streets.

  13. During walking and running, hedgehogs step on the ground with their feet.
  14. In summer, the hearts of the hedgehogs make 180 beats per minute. In winter, when the animals hibernate, the heart rate slows down to 20-60 beats.

  17. Hedgehogs are single animals that make nests near each other but try not to intersect with other adults.
