Explanation:
In case of locomotion, Echinoderms use their tube feet to move about but some sea urchins also use their spines.Starfish extend their tube feet in the intended direction of travel and grip the substance by suction,after which feet are drawn backwards.
The type of locomotion in molluscs depends on the type of food they take.Gastropods and herbivore molluscs ate the types that secrete slime and slide over it by contracting their muscular foot.Bivalves are the shelled molluscs that are not able to move(sessile).They bury themselves under the earth.when natural disasters occur they are the ones which are in danger where as others are able to swim and move away while bivalves take sometime to dig and move away.
