Phylum Porifera
-Sponges: Do not have true tissues or organs. 3 classes: Class Calcarea Class Hexactinellida Class Demospongiae
Class Calcarea
-Calcium
Y = usual spicuole shape
Class Hexactinellida
-Silica
glasssponge
* = spicuole shape
passes light through sponge
Class Demospongiae
-Spongin
make up 80%
Phylum Cnidaria
-Nematocysts (stringers)
Class Hydrozoa
Class Scyphozoa
Class Anthozoa
Class Hydrozoa
-Hydra and Portugese Man of War
~largely in polyp stage
tell the difference between Hydrozoa and Scyphozoa
~Scyphozoa = true jellyfish, don’t have velum
~Hydrozoa Aequorea have velum
Class Scyphozoa
-True Jellyfish
No velum
largely medusa stage - Don’t see polyp stage often

-Flukes internal parasites (can be deadly) *no eyespots two suckers (anterior and mid ventral) identifiable by these suckers
Class Cestoda
-Tapeworm internal parasite have scoley (head with hooks and suckers), strobila, neck, and proglotids (mature proglotids can detach to spread eggs)
Phylum Rotifera
-Rotifers
mastex and corona
