How old are blue whales?
Scientists have discovered that by counting the layers of a deceased whale’s waxlike earplugs, they can get a close estimate of the animal’s age. The oldest blue whale found using this method was determined to be around 110 years old. Average lifespan is estimated at around 80 to 90 years.
Was Megalodon bigger than a blue whale?
Monster-size sharks in The Meg reach lengths of 20 to 25 meters (66 to 82 feet). That’s massive, although a tad smaller than the longest known blue whales.

Dolphins and beluga whales sleep by shutting down one hemisphere of their brain at a time.

While half of the killer whale’s brain catches up on sleep, the other half controls the breathing.
