Squid have eyes like dinner plates
Are the two summits of mollusc evolution. From humble winkles with simple eyes through whelks to cuttlefish, this great phylum of animals has progressed through most of evolutionary time. Cuttlefish have wonderful vision to cope with their exotic colour change signals to each other, but these two huge, 10m squid relatives had to have a special adaptation-size.They are subjected to one of the great unseen predations of all time. No-one has ever witnessed the struggle between one of the two giant squid and their arch-rival, the monster of three miles deep. It is of course the giant sperm whale, from whose scars we can tell the progress of many such battles. Sonar echo-location spots the squid for the whale in the darkest depths of the ocean. The squid has a selective need to develop better and better senses too. Its answer has been the detection of huge objects in the dark, and these eyes are the tool. Mathematical calculations estimate the two large eyes could better detect a pattern of point sources from the bioluminescent microorganisms in the water at 120m. A sperm whales bulk would disturb those light sources in an unmistakeable way. The speed of the squid's jet propulsion could then evade the predator.
