Starfish. Scanning electron micrograph of the underside of a starfish (class Asteroidea),showing the mouth (centre) and the ambulacral grooves running down the centre of each of the five arms. Each arm also has hundreds of podia,minute foot-like suckers,within the groove that allow the starfish to move on the seabed in any direction. At the end of each arm is a microscopic eye (not seen),which enables the starfish to see its prey. Starfish can choose to be predators,plant-eaters or scavengers,depending on their environment | |
