Sea Stars are able to move their "feet" or legs by expanding them. This makes the muscles strong enough to move around on another surface this is how a sea star gets around. They also have bristles on their bottoms that allow them to grip onto rocks and other hard surfaces. Sea Stars does not move a lot, but move in order to eat and find safer shelter.

Sea Urchins move in a plethora of ways making them a surprising mobile creature. They can walk along the bottom of the ocean by using their feet, spines or even their teeth! Many urchins walk fastest on its legs, but walking with its spines could help them blend into the environment better. When urchins move off the bottom of the ocean, they kick with their feet. They often do not have the strength to kick for long so they fall back to the sand.

Sea Cucumbers are not very active animals, but when they move, they are pretty effective. Like the urchin, cucumbers have tiny feet that allow it to move along the ocean floor at a steady pace. However, if they are getting hunted by another animal, they can swim by thrusting their body back and forth in the water. Since they are so sticky, when they move they of then pick up plants and small bits of food on their body's because of the sticky tentacles.
