Coral reefs and the life they support; mysterious creatures that thrive in the deep; birds that depend on the sea: our oceans are a realm of discovery. From the shifting shorelines of the British coast to the vast depths explored in David Attenborough’s latest documentary Oceans, these books reflect the wonders and fragility of marine life. Whether documenting sea creatures, revealing scientific insights or celebrating the ocean through photography and guides for children, they invite readers to dive beneath the surface and connect with the blue planet.
