It’s not exactly sleep – it is more like doze. Humpbacks are not ‘conscious breathers’, which means they have to think of breathing (just like we human beings) under water. Nevertheless, researchers believe they have the ability to switch off half of their brain to relax. The other half of their brain is thinking of breathing, being aware of predators like orcas, or taking care of the baby if it is a mother.
