Females may store sperm for a considerable period of time before fertilizing their eggs. Eggs are released on the female's abdomen, under the tail flap, secured with a sticky material. In this location, they are preserved during embryonic development. Females carrying eggs are called "berried" because eggs are similar to round berries.

When the small larvae develop, they release the female crab under water. These small larvae can swim and take advantage of the currents of the water. When the crab becomes a little bigger it starts to return to the ground. goes.
