How do kina feed?

Answer 1

Kina, or sea urchins, feed primarily by grazing on algae and other organic matter found on the ocean floor. They use their specialized mouthparts, called Aristotle's lantern, which consist of five teeth that can scrape and cut food. By moving across rocks and substrates, they can efficiently access their food sources. This feeding behavior plays a crucial role in controlling algal populations in marine ecosystems.
