Case Based MCQs

Direction Read the following and answer the questions that follow

The water vascular system in echinoderms is a unique and defining characteristic that acts as a vital part of whole animal’s body. It consists of hundreds to thousands of tubefeets that are found in the ambulacral grooves. Due to this, this system is also called ambulacral system.
