phylum cnidaria
(coelenterata)

more Kingdom Animalia invertebrates:
phylum annelida
phylum mollusca

phylum arthropoda
phylum echinodermata

and then there are the
Kingdom Animalia chordates:
phylum chordata

Phylum Rotifera
rotifers are microscopic, multicellular, organisms that are currently under taxonomic revision.

phylum arthropoda

Phylum Platyhelminthes

Kingdom Animalia includes
several phyla:
Phylum Porifera
Phylum Cnidaria
Phylum Platyhelminthes
Phylum Nematoda
Phylum Annelida
Phylum Arthropoda
Phylum Mollusca
Phylum Echinodermata

ALL
except members of
Phylum Chordate
are invertebrates

phylum porifera

phylum echinodermata

phylum mollusca

phylum annelida

Phylum Nematoda

14. Draw and label Dirofilaria immitis (dog heartworm), and red blood cells from a prepared slide. 40x.

15. Draw the preserved specimen of Ascaris (parasitic nematode). Draw and be able to distinguish between male and female

16. Draw encysted Trichinella in pork muscle, w.m prepared slide. 10x. Label the muscle, cyst and nematode.

17. Draw the live specimen of a free-living nematode. 10x.

Q: Why do nematodes move in a whip-like fashion?
Nematodes move by contracting their longitudinal muscles which causes their bodies to flex laterally.
