Red sea crabs Breeding / Reproduction
At the time of mating, the superior male make a defensive "confine" around the female. The male carry these confine until she gets ready for mating. They arrive at the coast to mate and this happens at such a time that the female could produce eggs and then burrow the eggs for few days. Then the eggs are released in the sea and this takes place at some time in the new moon. When these egg hatches the young ones live as larvae for about a month in the sea. These larvae are carried away by the water currents. Thus for the survival of these larvae they must reach to their favorable habitat.
