Examining the effect of tides on the oceans of the world and how sea-dwelling creatures have adapted to and taken advantage of them. Included: the largest tides in the world are seen at the Bay of Fundy; and a tidal bore is observed driving up the Amazon River. Also: sand-bubbler crabs scour the sand for microscopic food; snails surf waves into shore to look for food; and bottle-nosed dolphins herd mullet off the coast of Florida. Host: David Attenborough.
