Dolphins, whales and seals: the sleek, elegant, smart and powerful African mammals of the sea have more secrets than one would expect. Find out that the v-shaped blast the Southern Right whale breathes is actually condensed air. This mammal weighs up to 800 times more than an average man and can grow to be as large as 17 meters.

Seals are the only mammals that inhabit both the worlds of the sea and the land. Equivalent to a large catamaran, dolphins can race through water at incredible speeds. The human free-dive record is eight minutes. Find out how long mammals can stay under water for without surfacing for air. Did you know that land animals originated in the sea and that some eventually returned?
