What percent of the worlds oceans are shallow seas And how much marine life lives there?

Shallow seas, defined as coastal waters up to 200 meters deep, account for approximately 7% of the world's oceans. These areas are incredibly important for marine biodiversity, supporting an estimated 90% of all marine life.

The wide range of habitats found in shallow seas, such as coral reefs, mangrove forests, seagrass meadows, and sandy beaches, provides a diverse range of food and shelter options for marine organisms. These areas are vital breeding grounds for many fish species, and support countless other forms of marine life, including sea turtles, dolphins, whales, and various invertebrates.

Moreover, shallow seas are highly productive ecosystems, contributing significantly to the global carbon cycle and oxygen production. They also act as natural barriers, protecting coastal areas from erosion and storm surges.

Protecting and preserving shallow seas is crucial for maintaining the health of our oceans and ensuring the survival of a vast array of marine species.
