What do intertidal echinoderms eat?

Intertidal echinoderms, such as sea stars, sea urchins, and cucumbers, have varied diets depending on their species. Many feed on algae, small invertebrates, and detritus, while others may prey on mollusks or barnacles. They use their specialized feeding structures, like tube feet or eversible stomachs, to capture and consume their food. Overall, their diet plays a crucial role in maintaining the balance of intertidal ecosystems.
