In a stunning breakthrough for UK marine biodiversity, a rare cold-water coral reef has been discovered off the southwest coast of England during the filming of Ocean with David Attenborough. At the heart of this hidden underwater world lies the pink sea fan coral (Eunicella verrucosa), a protected and slow-growing species that’s become a symbol of hope for Britain’s marine ecosystems.

Unlike the colourful tropical reefs found in sunlit, shallow waters, the UK’s cold-water coral reefs thrive in deep, dark, and frigid environments. These corals don’t rely on sunlight, making them resilient yet vulnerable ecosystems, often overlooked in mainstream conservation. The discovery of this flourishing deep-sea coral ecosystem suggests that parts of the UK seabed remain relatively untouched and may be quietly harbouring rich biodiversity.
This rare coral reef discovery also highlights the importance of marine protected areas in the UK, where reduced human disturbance allows delicate species like the pink sea fan to thrive. Found primarily in the southwest, including around Cornwall and Devon, these corals offer critical habitat for fish, crustaceans, and invertebrates.
As climate change and ocean warming pose increasing threats to marine life, protecting and understanding these hidden marine ecosystems is more urgent than ever.
