| DESCRIPTION: |
1 videocassette (15 min.) : sd., col. , 1/2 in. |
| NOTES: |
Derived from a different evolutionary path than other major invertebrate groups (molluscs, annelids, arthropods), the echinoderm line has branched into five major classes of marine animals: sea stars, sea urchins, brittle stars, sea cucumbers, and feather stars. Echinoderms begin as bilaterally symmetrical larvae that eventually develop the radial symmetry seen in the adults.. |
