Part Male, Part Female, Fully Mysterious!

"It was unreal," Watson said. "I've never seen anything like that, and I've worked the water all my life.''
Scientists said the crab, caught May 21 near Gwynns Island in the lower bay, is an extremely rare creature called a "bilateral gynandromorph" -- that is, split between two genders -- with its right side female and its left side male.
Before turning over the crab to the scientists, Johnson and other watermen conducted their own experiment into its sex life, with bewildering results. They dropped a female crab, which was just about ready to mate, into its tank.
First, the half-and-half crab cradled the female under his legs, as a male crab would do in preparation for mating.
Then, the crab seemed to lose interest in the female and let her go, Johnson said.
Then a day later . . .
"He ate half of her," Johnson said.
"The first day, the male side was coming out, the next day, it was the female side," said Lipcius, noting that in the wild, female crabs will often eat other competing females after they have shed their shells and become vulnerable.
