These aquatic mammals can stay awake and alert for up to 14 days.

The secret lies in unihemispheric sleep, that is, in the ability of these sociable and intelligent animals to let one half of their brain sleep while the other half is awake.

The process takes place by switching between the awake part of the brain and the resting part of the brain every two hours while the dolphins are resting.

The alert part of the brain is constantly "watching" for predators such as sharks that could threaten the safety of the dolphins, but it also informs them when it's time to surface and breathe air.
