How do whales sleep? When are they most active? The beautiful thing about cetaceans is that they can be active any time of day! Research shows whales and dolphins sleep unihemispherically: half their brain on half off. The evening shift on the water was chock full of activated common dolphins and a very friendly and reliable humpback whale. As the sunset, the frenzy continued and the humpback breached: twice!
We’ll see who clocks in tomorrow morning on the water with me and the crew of SDWW.
