Story summary

Marine heatwaves in the United Kingdom have sparked a surge in sunfish sightings.
The heatwaves have shifted fish populations from cold-water to warm-water species, moving cold-water fish north to Scotland and increasing bass, comber, triggerfish, sardines and anchovies.
Researchers warn the UK may have lost 92% of its seagrass meadows since the 1930s.
The Seagrass Ocean Rescue project aims to restore 15% of seagrass meadows by 2030.
