Open in App
Solution
The correct option is D Earthworm
The setae and the coelomic fluid also assist in the locomotion. The body of earthworm exhibits extension, contraction and anchoring in the anterior and posterior regions during locomotion. Circular and longitudinal muscles of the body wall are useful in extension and contraction of the body. The septa mechanically isolate each segment, keeping the coelomic fluid. The hydrostatic skeleton, making such fine-tuned movements impossible.So the correct answer is 'Earthworm'.
