Question

Do sea urchins eat seaweed?

Answer 1

Yes, sea urchins are known to eat seaweed. They are herbivores and feed primarily on different types of algae and seaweed. Sea urchins use their sharp teeth-like structures, called "Aristotle's lantern," to scrape and graze on the surfaces of rocks, coral, and other underwater structures where seaweed grows. They play an essential role in maintaining the balance of marine ecosystems by controlling the growth of seaweed populations.
