Others have electric-blue ones. Scallops have up to 100 eyes. The square crystals grow inside the cells of the scallop’s eye, filling them up. They’ve finally reconstructed the structure of the mirror in glorious detail, confirming many of Land’s ideas, and fleshing others out. How is this related to a colour that is fast disappearing in the natural world? “Nothing checked out, and this is as good a hypothesis as any,” he says. As you can see, these eyes are very important because they let them know if there are threats approaching. The big eyes are for detecting movement, while the other 3 are for detecting light.

No, as a scallop is an invertebrate. These eyes represent a particular innovation among molluscs, relying on a concave, parabolic mirror of guanine crystals to focus and retro-reflect light instead of a lens as found in many other eye types But actually they do have eyes, and so many more that you could have ever expected. image: Wikimedia Commons You may have eaten countless scallops before now, and you might think they don’t have eyes.
