Mass gatherings of spider crabs ‘not dangerous to humans’
Conservationists are urging visitors to Cornwall in England’s south to enjoy the site of mass spider crab gatherings in a bid to counter claims the crustaceans are “venomous”.
There have been sightings of hundreds of crabs grouping together in knee deep water in popular tourists spots including Newquay, St Ives, Falmouth and St Austell in recent weeks.
The natural phenomena, in which the crabs band together for protection while moulting their shell in order to grow a new exoskeleton, was spotted just once in the UK last year at Falmouth beach.
Spider crabs are most populous in the warmer waters of the Mediterranean Sea, but their numbers have been surging in UK waters in recent years.
