TRANSCRIPT

  • Honors Marine BiologyOctober 11, 2012Module 3: MangrovesModule 4

  • Class Challenge

  • QuizSara Kane from the Sarasota Bay Estuary Program spoke with our class last week.

    Write in complete sentences the significance of this program and 3 additional things that this program has accomplished since its inception in 1989.

  • MangrovesLike the salt water marsh plants, Mangroves are salt-tolerant plants.

    They cannot tolerate frost and are therefore found in the tropics and sub-tropic areas.

  • 4 Types of MangrovesThe White Mangrove

    The Red Mangrove

    The Black Mangrove

    The Buttonwood Mangrove

  • Marine Invertebrates I

    Invertebrates: Animals that do not possess a backbone.

    Vertebrates: Animals that possess a backbone.

  • Sponge SpiculeLarger and more complex sponges are beg enough to require a form of support. Some have a network of SPICULES made of calcium carbonate or silica.

    These form the skeleton of the larger sponges, supporting them so they stand upright in the water.

  • Sponge ClassificationIn order to classify sponges, a marine biologist often looks at the sponges unique spicule shape rather than looking at a sponges overall appearance.

  • SpongesSpongin: Web-like skeleton of elastic protein fibers.Amoebocytes: Cells within a sponge that produce its skeletal, perform digestion, and cell damage.Gemmule: A group of cells surrounded by a shell made of spicules.Larva: An immature stage of an animal that appears different from the adult stage.Metamorphosis: A complete morphological change from larval to adult form.

  • CnidariaAlso know as coelenterates. Contain a coel, a large body cavity.

    Jellyfish, corals, sea aneomones.

  • CnidariaHave specialized tissues that perform specific functions.

    Have the ability to move in a more intricate way than a sponge.

  • Cnidaria have a form of SymmetryThe three body types:Spherical symmetry: A body form in which any cut through the organisms center results in identical halves.Radial Symmetry: A body form in which any longitudinal cut (along the length) through the organisms central axis results in identical halves.Bilateral Symmetry: A body form in which only one longitudinal cut through the organisms center results in identical halves.

  • CnidarianCnidarians display radial symmetry, having no true head, front, or back.

    The only differentiation in these animals is that they have a side with a mouth an oral side and an opposite side an aboral side. Organisms in this phylum have one of two basic body forms: Polyp or Medusa. (figure 4.6)
