Lesson Planet
Chiton are mollusks that have no face, but have many eyes made from a component found in limestone. Here is a video that introduces nine ways animals see the world, including through rock eyes like chiton. Viewers learn about a vision super power held by termites, how many colors a mantis shrimp can actually see, and all about a fish with four eyes—two above the water and two below.
