Pupil responses by the mirror-based eyes of scallops

Picture
The eyes of scallops demonstrate a light-evoked pupillary response
Above, the pupils of the eyes of the sea scallop Placopecten magellanicus constrict in response to the onset of light following a period of dark adaptation. We find that the pupils of scallops constrict to ~60% of their fully-dilated areas within several minutes of light exposure and dilate fully after ~45 minutes in the dark. Imaging and animation by Hayley Miller. To learn more, please see our publication in Current Biology.

Modeling the effect of the pupillary response of scallops
By limiting the effects of longitudinal spherical aberration, pupil constriction in scallops improves the angular resolution of the eye, Ray-tracing model and animation by Yakir Gagnon. To learn more, please see our publication in Current Biology.
