A rare sighting off Cornwall in the form of a long-snouted seahorse has been reported by a marine-biologist scuba diver working on the seagrass restoration project in Plymouth Sound.
Mark Parry, development officer of the Ocean Conservation Trust (OCT), came up with underwater video footage showing the long-snouted or spiny seahorse (Hippocampus guttulatus) in the seagrass.
The species was once common along the South Coast but largely disappeared with the destruction of the seagrass meadows that provided it with a nursery habitat.
Today the seahorses are known to exist only in isolated spots such as Studland Bay in Dorset, along with the short-snouted seahorse (Hippocampus hippocampus), the only other British species.
According to the Seahorse Trust seahorses can also be found along the UK’s west coast and all around Ireland, with some sightings on the UK east coast.
Parry told the Independent that he had never before seen a seahorse in the wild in the seven years that he had been diving in seagrass in the UK.
Work on England’s biggest seagrass-planting programme began in Plymouth Sound National Marine Park in late April.
The OCT has been leading the LIFE Recreation ReMEDIES project through which a team of diving volunteers are helping to plant 16,000 seagrass seed bags and 2200 seedling bags as a boost for the marine environment.
