Shark Week (1988) : 29x10

Sharks and dolphins have shared the ocean for ages, but only recently, scientists have begun to understand the true nature of the relationship between these two masters of the sea. It's hostile, and dangerous, mainly for dolphins. Dolphins would rather eat fish and swim with humans; sharks would rather eat dolphins and anything they can sink their teeth into. Dr. Mike Heithaus and his team bring new research that may solve why sharks attack dolphins far more than we ever knew.
