Most echinoderms are opportunistic feeders, meaning they will consume a variety of food sources depending on availability. Some echinoderms are herbivores, feeding on algae and plant matter, while others are carnivores, preying on small invertebrates or detritus. Very few echinoderms can be considered omnivores.
Echinoderms, such as starfish, have basal nerve ganglia that serve as a nervous system. They also have a water vascular system that acts as a circulatory system. They can reproduce, move, and digest food. Therefore, they are animals.
