Question Set: Phylum Echinodermata
  1. Explain how all echinoderms show five-sided radial symmetry when they look so different.
     
  2. How does a tube foot work? Explain using words and drawings.
     
  3. Most of the echinoderms have hard parts and spines for defense, but the sea cucumbers do not. How do sea cucumbers protect themselves from predators?
     
  4. How does the arrangement of skeletal structures differ in sea urchins, sea stars, and brittle stars? How do these differences establish the way these animals move?
     
  5. How is the skeleton of a sea urchin like the skeleton of a lobster? How is it different?
     
  6. Sea stars have no teeth, yet they eat other animals (corals, molluscs). How do they do this?
     
  7. Two powerful adductor muscles hold the shells of a clam together. Humans have trouble opening a live clam, yet a sea star can pull them apart. How do they do this?
