Kratts' Creatures S01E14 - Planet of the Dolphin

Chris and Martin head out to look for dolphins in the Caribbean Sea. Dolphins are very intelligent and the guys are eager to meet a creature with the reputation of being so friendly to humans. On their way, the guys meet many fabulous sea creatures, including sharks and sting rays. Learning about echo-location - one way dolphins communicate - Chris and Martin finally find a pod of wild dolphins and hang out with them. They discover dolphins love playing, almost as much as they do.
