Orche Sea Star (Pisaster ochraceus) by: Mimi Ditchie
The sea star is amasterful example of using a water vascular system. This begins from the aboral madreporite, where sea water is pumped into the sea star through the stone canal to the ring canal. From there, water goes through five radial canals, finally dividing to the individual tube feet. These famous tube feet, often admired by children when washed up on beaches, consist of hollow muscular structures attached to a fluid reservoir (ampulla).
