Rare sighting of common octopus captured on camera off Cornish coast – video

Huge numbers of octopus have been seen along Cornwall's coastline this month in what experts are describing as a 'bumper year' for sightings. Conservation officers now believe this could be evidence of an octopus population boom – an event last recorded along England’s south coast more than 70 years ago. Divers and snorkellers have reported an increase of common octopus in Cornwall, particularly around the Lizard peninsula. Despite its name, this large species of octopus is rarely seen in UK waters and has been recorded by the Cornwall Wildlife Trust just twice a year on average
