Meeting Abstract 108.3  Sunday, Jan. 6  Visual acuity in deep-sea fish and mollusks GAGNON, YL*; JOHNSEN, S; Duke University; Duke University 12.yakir@gmail.com The ocean can be a challenging environment for visually active animals. Downwelling light is absorbed by the water and decreases exponentially with depth. At epipelagic depths (0-200 m), targets reflect ambient light and create extended […]
