Seeing in the dark: eye reduction and loss in deep-sea snails

Animals live in darkness all over the world. Whether they live in caves, burrows or the ocean abyss, they share many common features such as a lack of coloration and long, slender limbs and antennae. The loss of eyesight is one of the most profound and widely-reported of these. Over 150 years ago, this phenomenon was a source of frustration for Darwin, who could not understand any disadvantage to eyesight and decided the loss of eyes must be ‘attributed wholly to disuse’.
