   2. Distome

   3. Echinostome

   4. Monostome

5. About 60 miles south of the Arizona border, on the Gulf of California, is a small Mexican village (not on the map) called Cholla Bay. It is composed, in part, of Americans who, for one reason or another, have chosen to exit the US and remain obscure. There is a bar there called J.J.'s, and you can sit for hours on the patio overlooking a large estuary imbibing pitchers of Margaritas. Within the estuary are millions of snails, and resident populations of invertebrates, birds, fish, etc. You crack open some of the snails and find numerous sporocysts, and also rediae that are producing numerous furcocercous cercariae. Based on your knowledge of trematode life cycles, propose a HYPOTHETICAL (but very logical) life cycle for this trematode (10 points).

   
   

   
   

   
   

6. Within the cestodes are multiple, distinct types of attachment organs on the scolex. List four distinct types and tell how you can distinguish each from the others (2 point each, 8 points total).

   4. .

   
   

7. Diagram the complete life cycle of Dicrocoelium dendriticum. Label all stages (10 points).

   
   

   
   

8. Diagram, compare, and contrast the life cycles of typical terrestrial versus aquatic cestode life cycles (10 points).
