LESSON OF THE DAY FROM THE ANIMAL WORLD: No matter how huge you are... sleeping is a must. GOOD NIGHT, BUDDIES!!! Humpback whales are the furthest-traveling mammals on the planet, capable of journeying some 3,000 miles a year as part of their annual migration. But all that swimming sure can tucker a whale out. Whales typically sleep at night, which makes this a rare encounter — though other remarkable footage has been captured of sperm whales napping too, and as a group, no less. Unlike humans and other non-aquatic mammals, respiration is not involuntary for whales and dolphins. In order to keep from drowning as they sleep, these animals shut off half their brain at a time, allowing them to return to the surface periodically to breathe. ~ thedodo
