Study Guidelines for BIO 182L Final Lab ExamInvertebrates and Earthworm Dissection Lab
• Describe the distinguishing characteristics of several invertebrate phyla, including phylum Porifera,
phylum Cnidaria, phylum Platyhelminthes, phylum Annelida, phylum Mollusca, phylum Nematoda,
phylum Arthropoda, and phylum Echinodermata.
• Porifera- (sponges)- no tissues
Habitat- mostly marine
Motility- adults are sessile (immobile, attached to something), filter feeders,
Reproduction- hermaphrodites- sperm and egg is produced by same individual, asexual by
fragmentation or sexually by formation of gametes
Water transport- water enters through pores then enters central cavity (spongocoel), this is used
for eating, and removal of waste
Choanocytes- collar cells that line spongocoel and canals
• Cnidaria- (jellyfish, coral, sea anemones)
Habitat- mostly marine, either sessile or free-swimming
Body wall- diploblastic Body symmetry- radially
Digestive system- central gastrovascular cavity, one opening that is mouth and anus
Body forms- polyp or medusa
• Annelida- (earthworms, leeches)
Habitat- may be aquatic, either marine or fresh; or terrestrial; free- living and sometimes parasitic
Symmetry- bilateral symmetry
Body wall- triploblastic
Movement- longitude and circular muscles, aquatic annelids have lateral appendages, parapodia -
closed circulatory system
• Mollusca- (bivalves, cephalopods, octopuses, etc.)
Habitat- terrestrial or aquatic, marine or freshwater
Body symmetry- bilateral
Body wall- triploblastic
-unsegmented body (head, muscular foot, visceral hump, radula)
Mantle- surrounds body organs
• Arthropoda- (insects, arachnids)
Body symmetry- bilateral symmetry
Body wall- triploblastic
-exoskeleton
-body is divided between head, thorax, and abdomen
jointed appendages
Respiration- book lungs
• Echinodermata- (starfish, sea cucumber, sea urchin) -endoskeleton
Body symmetry- adults are radial, larvae are bilateral
Body wall- triploblastic
-complete digestive system
-mouth is on ventral side while anus is on dorsal side
, Reproduction- sexual, external fertilization, free swimming larva
• Identify and classify representative specimens into their respective group from the following list of
choices: Porifera, Cnidaria, Annelida, Nematoda, Platyhelminthes, Mollusca, Echinodermata,
Arthropoda, and Crustacea.
