Question

Which of the following organisms have tube feet as their locomotory organs?

• A. Jelly fish
• B. Cuttle fish
• C. Star fish
• D. Devil fish

Answer 1

The correct option is C Star fish

The water vascular system is a characteristic feature found in the echinoderms like the star fish. The system is a hydraulic system which is used by the organisms for respiration, food circulation, waste removal, excretion and locomotion. The system is composed of canals which can connect the tube feet. They can perform movement by contracting muscles and the force generated by water into the tube feet. This causes them to extend and push against the ground. The feet are then relaxed to allow the feet to retract.

Thus, the correct answer is option C.
