Urchin

     About the Urchin    The urchins have needles on them so they can easily protect themselves from other predators and it is really painful so the predetor will probably just run and see the doctor. How can you tell if the Sea Urchin is a girl or a boy well the the urchin is half boy and half girl so you tell these facts to everybody.   What the Urchin eats people might ask well the urchin eats algae,Invertabrates, mussels , sponges, brittle stars, and crinoids . But the most favorite food of the Urchin is the sea otter and wolf eels. Urchins don't care about there babies or they keep them in there spines.Sea Urchins sometimes don't care about there babies because they just let them go freely in the ocean so the other animals can eat it. The Sea Urchins have accually have been here for a long time.  So long time that they have been here sense the Ordovcian period. They have almost been extinct in the palezoic era.
