International Online Article: According to Japan's "Mainichi Shimbun" reported on September 25, a hermaphrodite lobster appeared on Theoshi Island in Toba City, Mie Prefecture, Japan. According to the county's Fisheries Research Institute, this phenomenon is very rare and is caused by the interlacing of genetic information of fertilized eggs.

It is reported that the lobster was found by a hotel owner. He bought a total of 500 lobsters from the 16th to the 20th, and found one of them with its belly facing up on the evening of the 24th. When I took it out, I found that his left body was reddish brown and his right body was black. The shrimp has died, and its feet and tail have been eaten by its kind.

A researcher at the Mie Prefectural Fisheries Research Institute who has been working on lobster breeding technology for 23 years said, "It's very rare, this is the second time I've seen this lobster." As for the reason, he explains, "It is possible that when a fertilized egg splits into 2 cells, the genetic information that determines the color of the male and female and the body causes this phenomenon to occur." It is almost certain that this is a hermaphrodite lobster. ”
