Cuttlefish: Reigning Eye-Spy champions since 160,000,000 BC đđ
Weird, wonderful and shaped like a âWâ, the wavy pupils and âeyelidsâ of a cuttlefish are designed to help even out the scattered light of a reef, revealing hidden prey. Â Cephalopod eyes contain just one kind of color-sensitive protein so as far as we know, cephalopods canât see in color. But because each color of light has a different wavelength, and each bends a little differently as it enters a cuttlefishâs eye, itâs possible for one color of light to be in focus while another is still blurry. By purposefully and rapidly focusing and blurring their vision, cephalopods can essentially differentiate between colors, and potential prey, depending on whatâs in focus!
