  "summary": "The ecological radiation of organisms in diverse light environments depends, in part, on adaptive alterations within visual systems, particularly retinal photoreceptors and their visual pigments. Evidence of visual adaptation occurs across vertebrate lineages but is notably lacking in turtles, despite their complex visual system with up to eight photoreceptor cell types and five visual pigments.…",
