Honors Marine BiologyOctober 11, 2012Module 3: MangrovesModule 4
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.
Sponges Lab: Diagram of a SpongeFigure 4.2 page 78
Sponge Body TypesFigure 4.3
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)
