| Sea urchins are pincushion-like animals. The sea urchins have thin, sharp spines that can grow between 10 to 20 cm long. They have hundreds of tiny, tubed feet and five teeth in the middle of their back. The sea urchin's teeth continue to grow throughout it's life. They use their teeth to pull, tear and rip algae from rocks.Barcelona Aquarium,Spain |
