Two Canadian fishermen have been celebrating catching bright blue lobsters over the last few days. But how rare are these striking-looking crustaceans, asks Justin Parkinson from BBC News.
“The American lobster is usually a sort of greeny-brown, so anything bright blue would look very odd to fishermen there,” says Dr Charlie Ellis, a researcher at the UK’s National Lobster Hatchery, in Cornwall.
“But European lobsters tend to be a duller blue colour. The real sort of iridescent blue is still rare here, but the difference is that, to a European fisherman, it will seem less completely out of the ordinary than it would seem to a North American.”
Charlie Ellis thinks the probability of a lobster being bright blue may be as low as one in a few hundred thousand. But another British expert, Dr Andrew Parker of Oxford University’s zoology department, disagrees – he backs the one-in-two-million estimate.
