Abstract

Tiger salamander retinae undergo changes in photoreceptor morphology following metamorphosis from aquatic to terrestrial phases. Visual angle subtended by prey stimulus necessary to elicit a strike response was measured for both phases. Terrestrial animals responded to smaller stimuli compared to aquatic. Increased acuity may enhance survival in terrestrial environments.
