Seagrass may look unassuming, but healthy oceans depend on the huge meadows that grow in temperate and tropical waters.
Far more megafauna species use coastal wetlands than we thought. And it affects the way we need to address the extinction crisis.
The sediments that accumulate beneath seagrass meadows can act as secure vaults for shipwrecks and other precious artefacts, by stopping water and oxygen from damaging the delicate timbers.
New research highlights the role of sea turtles and dugong in the dispersal of seeds and maintenance of seagrass meadows, an important marine habitat and the primary food source for both animals.
Seagrass meadows play a significant role in supporting world fishery productivity.
The 'canaries of the sea' are sending a worrying message about the health of our oceans.
