  1. Echinoderms – Spiny Skin • Echinoderms movies

  2. Echinoderms Are: • Starfish • Sea Lilies • Feather Stars • Basket Stars • Sea Urchins • Sea Cucumbers • Sand Dollars

  3. There are 5 characteristics: • Radial Symmetry • Spiny skin • Internal skeleton • Water vascular system • Tube feet

  4. The internal skeleton of an echinoderm is made of calcium carbonate bony plates that are bumpy or spiny for protection. • An echinoderm’s water vascular system is a system of canals that carry food and oxygen and remove wastes. • The water vasuclar system also helps an echinoderm move.

  5. Echinoderms have tube feet used for moving and getting food. Tube feet movie 2 Tube feet movie

  6. Reproduction • Sexual • Larva Stage Reproduction Movie

  7. 5 Class of Echinoderms • Crinoidea- Sea Lillies • Ophiuroidea- Brittle Stars • Echinoidea- Sea Urchins and Sandollars • Holothuroidea- Sea Cucumbers • Asteriodea- Starfish

  8. Crinoidea (kri-NOID-ee-uh) • sea lilies and feather stars • sessile and mobile • 5 arms extend and branch • tube feet filter feed and respire • mouth faces up

  9. Ophiuroidea (OH-fee-yoor-OID-ee-uh) • long narrow, flexible arms – move quickly basket stars

  10. Echinoidea (EK-uh-NOID-ee-uh) • sea urchins and sand dollars • endoskeleton called test • sea urchins eat by scraping algae with jaw-like Aristotle lantern • Sand Dollars live along seacoasts • short spines used for locomotion sand dollars

  11. Holothuroidea (HOH-loh-thuh-ROID-ee-uh) • Sea Cucumbers– soft body • Armless, they burrow • Tube feet around mouth Sea cucumbers movie Sea Cucumber movie 2

  12. Asteriodea (AS-tuh-ROID-ee-uh) • sea stars • 5 to many arms

  13. A starfish is able to re-grow it’s arms. • A starfish uses its tube feet to move and to open it’s food (bivalves).

  14. Digestive Gland Reproductive Gland/Gonads

  15. Starfish Eating Canals and Stomach

  16. Water Vascular System

  17. Kingdom of Animals Invertebrates • Porifera – Sponges • Flatworms – Turbellaria, Trematoda,,Cestoda • Roundworms- Nematoda • Rotifers • Mollusks – Gastropoda, Bivalves, Cephalopods • Annelida- Oligochaeta, Polychaeta, Hirudinea • Cnidarians- Hydrozoa, Scyphozoa, Anthozoa • Arthropods – Crustacians, Arachnids, Myriapods and Insects • Echinoderms – Crinoidea, Ophiuroidea, Echinoidea, Holothuroidea, Asteriodea.

  18. Invertebrate Exam • Be able to identify organisms by Phylum and Class/Order name. • Know characteristics of organisms – reproduction, eating, body plan, special features, etc. • Be able to identify structures off of dissections we have done.
