tube feet can suck anything, but moves slow.
Using its tube feet
No, mollusks do not have tube feet. Tube feet are a feature of echinoderms, such as sea stars and sea urchins, which they use for locomotion and feeding. Mollusks typically have a muscular foot for movement instead.
Echinoderms use their tube feet by using their water vascular system, so their tube feet are basically controlled by a water pressure system. Tube feet are adapted to a different uses in the groups of echinoderms by being able to use their tube feet to attach to objects as well as for protection and the gaining their nutrients.
Echinoderms, such as seastars and sea urchins, use their tube feet to move. Tube feet have suction discs which allows the echinoderm to crawl or stick to various surfaces.

By swimming using tentacles
Sea urchins, sand dollars, and sea stars are classified in the phylum Echinodermata. They have a spiny exterior and tube feet that they use for movement and feeding.
Parapodia are paired appendages found on polychetes, or marine worms, which are used for movement. Tube feet are found on echinoderms, like sea stars, which are also used for movement.
