What are the four major groups of echinoderms?
There are actually four major classes of echinoderms. These are Crinoidea, Asteroidea, Ophiuroidea, Eichionidea, Holothuroidea, and Concentricyloidea. The animals in these range from sea lilies to sea urchins.
How do echinoderms use their tube feet?
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.
What kingdom are echinoderms in?
Echinoderms are in the Animalia kingdom.
