tube feet are most common in echinoderms.
this is a phylum which includes animals such as sea stars and sea urchins.
echinoderms control much of the movement of their tube feet using their water vascular system.

The water canals, known as the water vascular system, includes the tube feet. When an animal like a starfish needs to move, it forces the water towards one section of it's body. This inflates the tube feet, or ampulae, with water. By redistributing this water systematically, the animal is able to move.
These tube feet have suction disks that enable the animals to crawl or attach themselves to objects. Think of a starfish "clinging" to the walls of the inside of a fish tank

The water vascular system of a starfish helps it move around by creating hydraulic pressure that powers the tube feet. These tube feet are connected to canals that run throughout the body of the starfish, allowing it to extend and contract them. By controlling the amount of water in the tube feet, the starfish can use them to grip and push off surfaces, enabling movement.
One of the functions for tube feet are for movment, and also so they can pry open their clams.
Tube feet are structures that operate like a suction cup.
One can purchase a Cartoon Animal Tube Dispenser which squeezes out toothpaste. This is the only product one can find that is available from anything called Animal Tube. The only other thing that can be found about Animal Tube is pornography.
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.
