Pupil response was studied photographically in four shark species: Ginglymostoma cirratum, Carcharhinus milberti, Negaprion brevirostris, and Galeocerdo cuvieri. Constriction and dilation take place in significantly less than 1 min in three of the four species. These rates suggest that pupil control is neuromuscular in some sharks.
