Question

Which of the following is not an adaptation of parasitic life for flatworms?

• A. Flat body
• B. Thick cuticle on body
• C. Production of eggs in great number
• D. Presence of hook

Answer 1

Answer: (A)

Flat body

• Flatworms have a flat body without any ridges or grooves. The flat body is not an adaptation to parasitic life in flatworms.
• It has a fairly thick protective covering or cuticle which is often raised into minute spines or scales. The cuticle provides greater protection to the parasites from the action of body fluids or digestive enzymes of a host.
• Flatworms produce a large number of eggs and the larvae of these flukes also reproduce within their hosts.
• Organs that helps the parasite to attach to the host tissues are well developed and these take the form of suckers, hooks etc.

So, the correct answer is option A.
