Parasitic flatworms (like tapeworms and liver flukes) show several special features that help them survive inside hosts.

Peculiar Features

• Hooks and suckers – For firm attachment to host tissues.
• Thick resistant body wall – Protects against digestive juices of the host.
• Reduced or absent digestive system – They directly absorb pre-digested food from the host.
• High reproductive capacity – Produce a large number of eggs to ensure survival.
• Complex life cycle – Often involves multiple hosts (intermediate + final).
