​

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
​Phylum Chordata

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.
