What is the difference between liver fluke and earthworm

Flukes are principally parasites of the liver of various mammals, including humans. Capable of moving along the blood circulation, they can occur also in bile ducts, gallbladder, and liver parenchyma.

Earthworm belongs to the group annelida.

They have a true body cavity which allows true organs to be present and protected in the body structure.

They also have segmented body.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
