Your group is to research an "assigned" (Kennedy's Lotto) invertebrate group.

------Sponges

------------------------Hydroids-------Jellyfish-----Sea Anemones

3. PLATYHELMINTHES- TURBELLARIA, TREMATODA, CESTODA; NEMATODA

----------------------------------------Flatworms --Free-living Flukes--Tapeworms--Roundworms

4. MOLLUSCA- GASTROPODA, BIVALVES (PELECYPODA),CEPHALOPODA

----"Soft Bodies"----Snails,slugs---------- Clams, oysters, etc...-------Octopus, squid

5. ANNELIDA- OLIGOCHAETA, POLYCHAETA, HIRUDINEA

Segmented Worms --Earthworms ----Marine worms ------Leeches

6. ARTHROPODA- CRUSTACEA, ARACHNIDA, CHILOPODA, DIPLOPODA

-----"Jointed Legs"---- Lobster, crab ----Spiders, ticks --Centipedes ------Millipedes

7. ARTHROPODA- INSECTA - Lepidoptera, Hymenoptera, Coleoptera, Odonata, etc....

----------------Insects (duh)--------Butterflies,moths- Ants, bees, wasps- Beetles- Dragonflies

8. ECHINODERMATA- ASTEROIDEA, ECHINOIDEA, OPHIUROIDEA, HOLOTHUROIDEA

-------"Spiny Skin"------------- Sea stars-------- Sea urchins------ Brittle stars------- Sea cucumbers

Using your text, in-class library, LMC, CD ROMS, and Internet sites, complete the following tasks:

One (1) person is to do the classification overview for the entire group:

1. The overall general distinguishing characteristics of the phylum.

2. The number of classes (with representatives of each) , and total number of species in each of the classes, general characteristics of each class

3. Relationships / similarities to other animal groups

4. Present 3 or more pictures of organisms representative of your group. You may use poster drawings, slides, overhead transparencies, or computer images.

All other members of your group select a class and research the following topics:

1. General physical characteristics ; representative species

2. Habitat (address)

3. Discuss the ecological niche (occupation in the environment), and manner of feeding.

4. Manner of reproduction, number of offspring, life cycle,...

5. Economic importance: as a food, crop pest, disease agent, parasite

6. Unique features: endangered species, pollution sensitive, symbiotic relationships,...

SPECIAL INSTRUCTIONS:

ORAL REPORT:

· Your grade will be determined by your presentation, not by the overall quality of the group.

· The total length of the group's presentation is to be no longer than 8 minutes.

· Each group must have at least three visual aides. (large, visible, labeled)

WRITTEN REPORT:

· Your paper should follow the above outline format using each area as a heading.

· The final write-up of all the research is due the next day after your group's presentation.

· Each paper is to be typed and two to three pages in length.

· A bibliography (typed) citing five or more references is required for each paper. They should not all be from the same type of media source.

· Double-space between lines (like this)

· Use an easy-to read font, size 10-12, NOT all capitals.
