The Life Cycle Female hermit crabs keep the eggs inside their shells until they are big enough. When they are ready, she releases them into the ocean. budd-eaze. com Every time the hermit crab grows, its exoskeleton doesn't so it needs to molt and grow a new one. It then needs to find a new shell to live in that fits. Some hermit crabs only live for 2 -3 months but they can live up to 15 -20 years. Hermit crabs will eat the exoskeleton that they shed to get extra calcium to help grow a new one. They hatch into a zoea larva. It grows by molting and then growing into a new exoskeleton. The claws and antennae develop during this time. crabstreetjournal. com After one more molt it becomes a hermit crab. Now it is ready to find a shell to keep it safe. http: //hermitcrabpetcare. com/wp-content/uploads/2008/ 14 http: //www. biology. duke. edu/johnsenlab/new%20 gallery
