What are these??

Platyhelminthes What is their main feature?? YES! That’s why their called FLATWORMS!!

Class Turbellaria - Planarians

The only free living class

Diversity Class Turbellaria - Planarians

Diversity

Class Trematoda - Flukes

Parasitic -not free living!! Sheep liver fluke Found in humans! (75mm)

Class Trematoda - Flukes Flukes are to fish what fleas are to dogs. They are very common and the leading cause of “flashing”. They are also the most common cause of ulcers, fin and tail rot and mouth rot.

Class Trematoda - Flukes Liver damage caused by flukes

Class Cestoda - Tapeworms

BIG!

Class Cestoda - Tapeworms Parasitic!

Class Cestoda - Tapeworms Adult tapeworms in small intestines - YUM!
