Half Male – Half Female Chesapeake Blue Crab

This crab, known as a bilateral gynandromorphism, is about 4.5 inches long and is estimated to be in its third year. It has both blue and red claws at the tip and an apron (lower abdomen) split in the middle. Typically, male gazami crabs have blue toes and a T-shaped apron, while females have a red tip and a wide apron. Gynandromorphic crabs have not been reported on the East Coast for at least 15 years. Gynandromorphism does not occur in mammals, but has been observed in lobsters, crabs, snakes, butterflies, bees, chickens and other birds.  Video, >click to read< 10:19
