Question

Quizplus · Accepted Answer

Sea cucumbers belong to the class Holothuroidea. This is because they have a long, cylindrical body with leathery skin and tube-like feet that they use for movement. Asteroidea, Ophiuroidea, Echinoidea, and Crinoidea are all classes of echinoderms, but they do not have the same body type as sea cucumbers.
