I tried an experiment to see how quickly a turtle could see another turtle. I put one of my three-toeds in the grass-it was fall and leaves were in the grass about the same color of these turtles shells. I put another turtle about 10 feet away and within 5-10 seconds the turtles saw eachother. I could barely see them! I thought their eyes must be able to see a glow off their shell!
I started to think about this when I put a baby turtle in the same pen with some adults and they right away picked up on the fact there was this new turtle in the pen-even though the baby was only 1 1/2 inches long and about 3/4 inch tall. At the time I thought shell color must be some kind of beacon for turtles, or their eyes may pick up some kind of rays off the shell-like being able to see in ultra violet. Has anyone noticed this in their turtles?
