Riley the dog is a bit of an adrenaline junkie.
How do we know this?
Because he followed his owner into an airplane... and then followed his owner out of that airplane before it landed!!
This is truly amazing.
Researchers have captured photos of wild dolphins and humpback whales off the coast of Hawaii, playing together!
A dolphin would lay on the head of a whale and the whale would lift it out of the water until the dolphin slowly slid back off the whale's head.
