The well-defined, often circular, dark pupil of most animals makes the vertebrate eye difficult to hide. Eyes are indeed considered key features for face recognition of predators, prey or conspecifics. Among fish, mechanisms for pupil camouflage are widespread: Eye masks, skin flaps, eyeshine and pupillary closure are among the adaptions that can reduce pupil conspicuousness. This project aims at understanding the role of such adaptations in the context of predator detection by presenting 3D models of scorpionfish that feature different eye types and shapes to its prey fish. More to come!
