Major Concepts and Skills:
1. List the major characteristics of Kingdom Animalia (multicellular,
heterotrophic, eukaryotic, mobile at some point during lifetime).
2. Identify the following anatomical terms while observing a specimen:
lateral, dorsal, ventral, anterior, posterior, cross-sectional view,
longitudinal section view, radial symmetry, bilateral symmetry.
3. List the 8 major phyla of invertebrate animals and differentiate between
them by identifying their major characteristics (porifera, cnideria,
platyhelminthes, nematode, annelida, echinodermata, mollusca,
arthropoda).
4. Explain the common meanings behind the Latin names given to the 8
phyla of invertebrate animals.
5. Give examples of species belonging to the 8 phyla of invertebrates
classified within Kingdom Animalia (ie: basket sponge= Phylum Porifera).
6. Explain how a sponge obtains its food through filter-feeding and identify
the major structures involved in this process.
7. Compare the absorption capabilities of a natural sponge and a synthetic
sponge.
8. Describe the mechanisms by which cniderians sting their prey to obtain
food.
9. Differentiate between medusa and polyp forms of cniderians and give
examples of species belonging to each group.
10. Observe the asexual reproductive process of “budding” in specimens of
hydra.
11. Discuss the impact that humans, the environment, and other living things
have on the survival of coral reef biomes.
12. Differentiate between the three phyla of worms (platyhelminthes,
nematoda, annelida).
13. Observe anatomical and behavioral differences and similarities between
two common species of annelids (earthworms and leeches).
14. Classify species of Mollusks by using field guides to identify various shells.
15. Differentiate between bivalve, univalve, and cephalopod mollusks and give
examples of species belonging to each group.
16. Explain how a mollusk creates a pearl and identify the major structures
involved in this process.
17. Describe the predator- prey relationship between echinoderms and
mollusks.
18. Describe how an echinoderm goes through the process of regeneration.
19. Differentiate between the five classes classified within Phylum Arthropoda
(insecta, crustacean, chilopoda, diplopoda, arachnida).
20. Explain the metamorphosis insects go through from the larval stage to
adulthood.
21. Describe the geographical differences between the major biomes of the
world.
22. Create an imaginative “new” species of arthropod, assign it a Latin genus
and species name, describe its habitat, and describe the adaptations it
uses to survive in its unique biome.
