  1. What are the divisions of organization? Kingdom Phylum Class Order Family Genus Species

  2. Animal Phyla of the Oceans

  3. Phylum Porifera • Benthic, suspension feeders • Asymmetrical • Sexual and asexual reproduction • No tissues or organs • Osculum- large opening(s) at top • Pores for incurrent water • Collar cells (choanocytes)

  4. Ex: Sponges Coralline sponge Encrusting sponges Tubullar sponge

  5. Wonderful world of sponges • http://www.youtube.com/watch?v=BW05vMziy2o • Sponge filtering • http://www.youtube.com/watch?v=T7E1rq7zHLc

  6. Benthic or pelagic Predators, passive suspension feeders Extra and intracellular Radial symmetry Oral and aboral surface Two stages Polyp – attached to bottom (sessile) Medusa – free swimming Nematocysts - stinging cells on tentacles Phylum Cnidaria Polyp Medusa

  7. Nematocysts firing • http://www.youtube.com/watch?v=6zJiBc_N1Zk&feature=related
