  1. Ophiuroidea Tyler d’Entremont, Michelle Johnson, Dana Marshall, Emma Whitley

  2. Introduction •Group of echinoderms •Brittle Stars and Basket Stars •Estimated to 2,000 species •Aquatic environments

  3. Taxonomy •Kingdom: Animalia •Phylum: Echinodermata •Subphylum: Asterozoa •Class: Ophiuroidea •Orders: Oegophiurida, Ophiurida, and Phrynophiurida

  4. Brittle Stars vs Sea Stars Brittle Stars can be distinguished from Sea Stars by their distinct body shape

  5. Anatomy and Characteristics

  6. Fun Fact Out of all echinoderms, brittle stars are the fastest.

  7. Reproduction • Spawning • Brooding • Cloning or asexual reproduction

  8. Spawning Eggs and sperm are released into the water.

  9. Brooding • Eggs fertilized in an internal chamber. • Released when at juvenile stage.

  10. Cloning • Adult method • Juvenile method

  11. Habitat •Waters from Arctic to tropics to Antarctica •Few adapted to survive in brackish waters •Basket stars mainly inhabit deep sea water

  12. Evolution Sea lilies gave rise to new Echinoderms.
