KODACHROME NATIONALGEOGRAPHICSOCIETY Camera's Sudden Flash Freezes Startled Fish Patrolling the Ocean Floor Ultrasensitive retinas and the water's faint phosphorescence let some fish see at depths that render man's eyes useless. Here a foot-long rat-tailed fish (upper) with bulging eyes and triangular dorsal fin swims with an eel-like companion (Ophichtus urolophus) at 3,300 feet. Coelorhynchus kishinonyci begins life in the sunlit ocean but on maturity migrates to the depths. National Geographic Society grants helped Dr. Harold S. Edgerton design the deep-sea cameras that captured the scene.
