Three-clawed Crab

The crab is believed to have a genetic mutation

A "mutant" crab with three pincers has been picked up off the Cornish coast.

Fisherman Jeff Brown caught the 20cm (7.8in) edible crab three miles off Portreath and realising its rarity, handed it into a Newquay aquarium.

The crab, christened Claudette by the Blue Reef aquarium staff, will be quarantined for several days before going on show.

Manager David Waines said additional fully formed pincers on crabs were "incredibly rare".
