mouth, madreporite, suckers
a purposes of a star fish sucker is because it sucks on everything
They have special suckers on their body which cling to the rocks like suction cups.
The suckers
the nervous system
If you look beneath a starfish you will see a groove under each "arm", from the tip to the "mouth" in the centre. The grooves are lined with "feet", flexible, muscular tubes with suckers at their ends.The starfish can travel by sucking onto any convenient surface with the suckers and dragging themselves along. Actually when a starfish hatches from its egg, it also can swim or drift along in the sea water. You could call that travelling too.
Star fish don't have eye spots, or eyes, they depend on their skin to detect light.
they are called suckers on the ends of the tube feet. they are controlled by the water-vascular system in echinoderms, such as starfish.
Starfish have limbs so that they can wrap them around their prey(mostly clams,mussels, etc.) and hold onto them entil they can open the prey up and eat it.
