Shallow seas cover only 8% of earth's surface, but contain the richest, most varied maritime life: from plankton and coral (literally vital for the very existence of reefs) to birds and from various invertebrates to mammals like seals, dolphins and whales and from sea snakes to countless fish species. Their ecological interaction is greatly varied and complex, often with nearby land to, even with deserts.

David Attenborough - Narrator
Our planet's continents are fringed by shallow seas. Rarely more than 200 meters deep, they lie on the continental shelves, which may stretch sometimes for hundreds of miles before the sea floor drops into deeper, darker waters. Altogether, they constitute a mere 8% of the world's oceans, but they contain the vast majority of its marine life.
