Study: Dolphins can remain awake for two weeks straight

Researchers from the National Marine Mammal Foundation say that dolphins can stay awake for 15 days at a time.

According to the LA Times, researchers from the National Marine Mammal Foundation in San Diego, California have discovered yet another remarkable fact about dolphins. Not only do dolphins manage to stay awake, but they do so without the aid of caffeine  or Red Bull— an enviable trait.

A dolphin’s ability to keep one hemisphere of their brain awake while the other sleeps allows them to remain alert for two weeks straight. In a study published Wednesday in the journal PLoS ONE, researchers determined that breathing underwater was not the only reason dolphins needed to rest only half their brain at a time. In fact, the new research suggests that the detection of predators is equally important.
