Scallops have up to 200 tiny eyes along the edge of the mantle lining their shells. The complexities of these mollusk eyes are still being unveiled. Dr. Daniel Speiser and colleagues Hayley Miller, Alexandra Kingston, and Yakir Gagnon published an article entitled "The mirror-based eyes of scallops demonstrate a light-evoked pupillary response" in the journal Current Biology. Their study reveals that scallop eyes have pupils that dilate and contract in response to light, making them far more dynamic than previously believed. Their insights into the physics of vision is further discussed in the Smithsonian Magazine here. Awesome work!
