1. Monogenetic trematodes are of fish, amphibians,
and reptiles: ectoparasites
2. Monogenetic trematodes attach to the surfaces of the , ,
, and the : gills, skin, mouth, fins
3. Digenetic trematodes are of both domestic animals ,wild
animals, and occasionally humans.: endoparasites
4. Describe the characteristics of Digenetic Trematodes: broad, leaf shaped, and flattened
5. What is the exception of digenetic trematodes' usual characteristics? Describe
them.: The schistosomes; they are long, thin, and worm-like
6. What is the hold fast organelle on digenetic trematodes?: ventral sucker
1/6
, 7. Flukes do not possess an anus; they release their digested food by regurgitat-
ing their cecal contents back into the tissues that they infect. This is called?: Fluke
puke
8. Most all flukes are hermaphroditic (male and female) except schistosomes.
True/False?: True
9. Digenetic Flukes have what type of egg: operculated eggs
10. When they contact water they hatch and become a motile stage called?: -
miracidium
11. What is it called when digenetic flukes penetrate the skin of a snail (1st
intermediate host and then develop into ?: sporocyst (holding spot/cell)
12. After a digenetic fluke develops into a sporocyst it becomes a
?: redia
