The next 9 slides contain general information about some of the
phylum and organisms

Protista
The Protista, = a kingdom of simple eukaryotic organisms, usually composed of a single cell or a colony of similar cells. Protists live in water, in moist
terrestrial habitats, and as parasites in the bodies of multicellular eukaroytes.

Protozoa- Single celled (Amoeba) Porifera- Body with pores( sponge)
Cnidaria- Tentacles/ Stinging cells (corals) Arthropods-Jointed bodies or legs (Insects)
Mollusks - animals with shells (Snails, clams) Echinoderms- spiny skinned (starfish)

Phylum Porifera - The Sponges
Name means "pore-bearing". Covered by tiny pores.

Phylum- Mollusk-Extinct Cephalopod- Belemnites • Belemnites have shell that resembles a cigar
rostrum. • The belemnites were highly successful during the
Jurassic and Cretaceous.

Ammonites
• Ammonites were among the dominant swimming invertebrates in Mesozoic seas.
• were so abundant and varied that the Mesozoic could be called the "Age of Ammonites".
