What are platyheminthes?
Monogenetic trematodes are found on what type of animals?
Ectoparasites of fish, amphibians, and reptiles
What are some characteristics of digenetic trematodes?
Have two intermediate hosts
(First and second intermediate hosts, and definitive host)

Where (in the body) are digenetic trematodes located?
Primarily in GI tract
Can also infect lungs and vasculature

Lung fluke in cats and dogs
What are eucestodes
Ribbon like flatworms
What are the kingdom, phylum, and class of eucestodes?
How are eucestodes frequently observed?
How do eucestodes receive their nutrients?
Absorb nutrients through their tegument (skin)
What is the intermediate host?
The animals harboring the larval stages of a parasite
What are nematodes?
Have enlongated, un segmented, cylindrical bodies

What are some characteristics of arthropods? (KNOW THIS)
Important in veterinary medicine
Serve as causal agents
Serve as intermediate hosts (helminthes, protozoans)
Serve as vectors (bacteria, viruses, spirochetes, chlamydial agents)
May produce toxins or venomous substances
May parasitize the host as adult or juvenile stages
What is the largest phylum in the animal kingdom?
Includes most of the ectoparasites seen in the veterinary profession
What are Protista?
Majority are free living
What are examples of Protista?
What are flagellates?
Have long whip like or lash like appendage that is used by a group of protozoans as means of locomotion in a fluid medium
What are amoeboa?
Have false feet
Amorphous (no real shape)
Flow along in a liquid medium
What are apicomplexans?
Most diverse and complicated
Locomotory organells are internal and not visible to the naked eye
