Cornwall’s waters are rich in biodiversity due to three ocean currents mixing in the area. The blending creates a perfect environment for diverse marine life. This includes species like common dolphins, grey seals, and several jellyfish, all thriving in the warm waters during summer. Popular diving sites offer a chance to see underwater landscapes, including seagrass meadows and maerl beds that support many marine species. Protecting these habitats is crucial for maintaining biodiversity and supporting local ecosystems.
