An electric-blue lobster was rescued from the lobster pot when it was discovered by a fishmonger at Billingsgate Fish Market in London.

Natural History Museum experts believe that a rare genetic variant created the lobster's unusual colour.

The rare crustacean is now settling into its new surroundings at the London Aquarium, though far from its home off the east coast of Scotland.

The stunning lobster was on sale at the fish market when it caught the eye of fishmonger, Rex Goldsmith, who said it was "the most striking blue lobster I have seen in my 30 years in the business," so he bought it and handed it over to the Natural History Museum in London.

Museum experts made a tank for the ailing lobster and it made a full recovery from its fish market ordeal.

The European lobster can theoretically live for as long as 15 years in the open seas, but due to heavy commercial fishing it rarely matures to that age.

"It's beautiful and I can't wait to take the kids to see it at the aquarium," Goldsmith enthused.
