The Surprising Secrets of Shark Sleep
Sharks need to sleep just like other animals, but they have unique adaptations for it. Many sharks must keep swimming to get oxygen, so they can use a special type of sleep called unihemispheric slow-wave sleep. This allows one half of their brain to sleep while the other half stays aware of their surroundings. Different species of sharks have different ways of resting, like finding sheltered spots or using special muscles to breathe without moving. Understanding these habits can enrich your scuba diving experience by deepening your appreciation of these incredible animals.
