21st Annual Smithsonian Magazine Photo Contest Natural World
The Eyes of the Scallop

Went snorkeling in Great Salt Pond last week with my small underwater camera and discovered entire microscopic world of this bay scallop. The scallop has 200 tiny eyes lining its mantle. Each of these eyes contains tiny mirrors, which is different from how most animals, including humans, see. Our eyes use lenses (the cornea) that focus and bend the light passing through it. The light is focused into the retina, or the light-sensitive tissue layer at the back of the eye. The scallop’s tiny mirrors are made from 20 to 30 layers of crystals, and the layers themselves are made of closely tiled crystal plates, like a mosaic. Together, it makes the picture clearer, and with its 200 eyes and a double-layered retina, scallop can see peripheral and central pictures at the same time.
