Answer 2

Hey Mate ⭐⭐⭐

Here's ur answer ⤵⤵⤵

phylum - platyhelminthes

3 classes are

Turbellaria

Trematoda

Cestoda

Turbellaria

The Turbellaria are one of the traditional sub-divisions of the phylum Platyhelminthes, and include all the sub-groups that are not exclusively parasitic.

Trematoda

Trematoda is a class within the phylum Platyhelminthes. It includes two groups of parasitic flatworms, known as flukes. They are internal parasites of molluscs and vertebrates. Most trematodes have a complex life cycle with at least two hosts. The primary host, where the flukes sexually reproduce, is a vertebrate.

Cestoda

Cestoda is a class of parasitic worms in the flatworm phylum. Most of the species—and the best-known—are those in the subclass Eucestoda; they are ribbonlike worms as adults, known as tapeworms.
