Question

Write the characteristic features of Flat worms with examples.

Answer 1

Phylum Platyhelminthes (Flat worms):
They are bilaterally symmetrical, triploblastic, acoelomate (without body cavity) animals.

• Most of them are parasitic in nature. Suckers and hooks help the animal to attach itself to the body of the host.
• Excretion occurs by specialized cells called flame cells. These worms are hermaphrodites having both male and female reproductive organs in a single individual.

Example: Liverfluke, Tapeworm.
