Sea Urchin

The life cycle of a sea urchin starts by spawning directly into the sea. First, the male spurts out his sperm. Then the female comes and spurts out her eggs. If the sperm and eggs touch, then a new baby sea urchin will form. After the male spurts out his sperm, more males and females come and spurt out their sperms and eggs. As a group thing there is a good chance that more baby sea urchins will Sometimes they eat bits of plants and small animals. Sea urchins have hundreds of tiny, tubed feet. They have five teeth in the middle of their back side. Sea urchins use these teeth to pull, tear and rip off algae on the rocks.These teeth continue to grow throughout the sea urchin's life.
