An unsuspecting fisherman has caught a rather scary looking giant crab off the coast of Cornwall

A fishing boat has landed the biggest crab ever found in British waters. The giant box crab is more than 3ft 3in long and normally lives on the seabed about 3km below the surface, but was caught by the fishing boat Harvest Reaper in much shallower water 80 miles west of The Isles of Scilly.

The boat’s skipper, Matthew Keast, handed the crab to Blue Reef Aquarium in Newquay when he returned to harbour. Aquarium manager David Waines described the find as “astonishing”.

“When you see him close up, he makes your flesh crawl with his long legs,” he said. “It’s like something from Alien or The Thing.”
