There is a "blue lobster" at the Natural History Museum in London, England. The fisherman who sent it said it was caught from the east coast of Scotland. After the fishmonger bought it for about 100 RMB, he thought it was beautiful and sent it to the museum.

Experts in the museum identified this lobster as a common local species in Britain, but its color was caused by a rare genetic variation.

Coincidentally, the New England Aquarium in Boston, USA also has a strange mutant lobster. It weighs about 1 kg body, half orange and half black, and the color dividing line is just at the center line of the body. Fishermen caught the lobster 20 miles northeast of Boston.

According to experts' analysis, this is a special development result of complete cell division when lobster eggs are fertilized for the first time. However, after cell division and development, individuals often have two gender characteristics at the same time, which means that this lobster is often "hermaphrodite". According to fishery officials, the probability that lobster has such a strange body color is only one in 500,000. In the past 10 years, similar two-color lobsters have also appeared in the waters of Maine, Rhode Island and Nova Scotia in Canada.
