Sea urchins reproduce by releasing eggs and sperm into the water, where fertilization occurs externally. Once fertilized, the eggs develop into larvae and eventually settle onto the ocean floor to grow into adult sea urchins. The larval stage allows for dispersion and colonization of new areas.

In the 1800s, too many sea otters were hunted for their fur. Without sea otters, fewer sea urchins were eaten. Soon, too many sea urchins were being born. Smaller fish could not survive, because sea urchins ate their supplies of kelp. These fish were food for sea stars and crabs. The sea stars and crabs began to die out.
