Bottlenose dolphins playing with humpback whales
I’d like to introduce a paper published last year in the journal Aquatic Mammals, which reports on two separate playful and – as you’ll see – uplifting encounters between bottlenose dolphins (Tursiops truncatus) and humpback whales (Megaptera novaeangliae).
The first took place on a January afternoon off the northwest coast of Kauai, when a group of eight bottlenose dolphins met up with a pair of humpback whales. Two of the dolphins — apparently adults — approached one of the whales, first appearing to surf the pressure wave created by the whale’s head as it swam, and later taking turns lying perpendicularly across the whale’s rostrum when it surfaced to breathe. Then, while one of the dolphins lay balanced over the end of its rostrum, the whale stopped and slowly lifted the dolphin high into the air. The dolphin maintained an arched position and made no effort to escape, allowing the whale to continue lifting until it was nearly vertical in the water, at which point the dolphin slid down the whale’s rostrum, dove into the water, and porpoised back to its fellow dolphins.
