Researchers Solve Mystery of The Sea Creature That Evolved Eyes All Over Its Shell

Posted by in categories: biotech/medical, electronics

Small, shelled, and unassuming, chitons have eyes unlike any other creature in the animal kingdom.

Some of these marine mollusks have thousands of bulbous little peepers embedded in their segmented shells, all with lenses made of a mineral called aragonite. Although tiny and primitive, these sensory organs called ocelli are thought to be capable of true vision, distinguishing shapes as well as light.

Other chiton species, however, sport smaller ‘eyespots’ that function more like individual pixels, much like the components of an insect’s or mantis shrimp’s compound eye, forming a visual sensor distributed over the chiton’s shell.
