More Information
The stone canal is essential for the water-vascular system in echinoderms, aiding in locomotion, feeding, and gas exchange.
Tips
A common mistake is confusing the stone canal with other parts of the water vascular system, like the ring canal. Remember, the stone canal connects the madreporite to the ring canal.
