Today I want to write about a cool little animal, the purple sea urchin.

Here are five interesting facts about them:

  1. These amazing little animals grow up to 10 cm across.
  2. They have very strong jaws on the bottom of their body that scrapes along the bottom of the sea and eats kelp.
  3. The spines on a purple sea urchin catch floating food and passes it along to the mouth.
  4. Although their spikes give them some protection, they are still eaten by sea otters, spiny lobsters, sea stars and the California sheephead.
  5. Purple sea urchins are found mainly in kelp forests in the Pacific Ocean along the west coast of North America from Mexico up to Canada where they are quite common.

I hope that you found these facts interesting and learned something new.
