Invertebrate Biodiversity lab Outline
Developed By: Kelly McKinnon -Reef Type: Barrier, with spur and groove Distribution: warm tropical waters of the world, typically offshore and separated from mainland by a lagoon. Currents and waves renew nutrients to the reef, sunlight penetrates the water allowing photosynthesis to occur.
Invertebrates
-Porifera: Sponges Principal characteristics of the phylum: simple multi -cellular organisms with no true tissue layers or organs. Sessile/non mobile. Sponges
-Cnidaria: Corals and Anemones (Anthozoa), Jellyfish (Scyphozoa) and Hydroids (Hydrozoa). Principal characteristics of the phylum: radial symmetry; polyp and/or medusa stages; nematocysts (stinging cells; named for this trait). Corals (Anthozoa)
Anemones (Anthozoa)
Jellyfish (Scyphozoa)
Hydroids (Hydrozoa)
-Platyhelminthes: flat worm Phylum, Tubellarians are most marine flatworms Slow moving worms Size can range from one to five inchesCan be confused with nudibranchs (shell-less snails), but Tubellarians are flattened and leaf-like
Invertebrate Biodiversity lab Outline
-Annelida: Segmented worms, Polychaetes, Fire worms, Feather Dusters, Calcareous worms Fireworms:
Feather Dusters: fan worms, sessile Calcareous Tube Worms: sessile
-Mollusca: Marine Snails (Gastropods), Chitons, Clams, Oysters, Scallops Mussels (Bivalves), Squid and Octopus (Cephlapoda) Marine Snails: largest mollusk group, 35,000 species
Chitons: very slow moving
Bivalves: can be sessile or motile
Octopus and Squids: highly mobile -Crustacea: Shrimps (sub order Natantia, Latin swimming), Lobsters (Palinura, backwards by tail), Crabs, and Barnacles Shrimp: very mobile Crabs: True crabs and Hermit crabs
Lobsters:
Barnacles: sessile

-Echinodermata: Sea Stars (Asteroidea), Brittle and Basket Stars (Ophiuroidea) Sea Urchins (Echinoidea), and Sea Cucumbers (Holothuroidea). All echinoderms are marine organisms, with a hard internal skeleton covered by a thin skin. They exhibit radial symmetry and are non sessile. Sea Stars: slow moving non-sessile
Brittle Stars and Basket Stars: slow moving, non-sessile
Sea Urchins and Sand Dollars: slow moving
Sea Cucumbers: slow moving
-Protochordata Tunicates Tunicates: sea squirts

A couple of clams were eating chocolate bars while two fish watched. "Did you see that?" one fish said, as the clams finished their treat. "They didn't offer us a single bite!" "What do you expect?" asked the other fish. "They're two shellfish."
Yea , it’s bad so come up with a better one and we will use it in the outline!!!
