They Have Favorite Colors

Like us, our shell-wearing reptilians are visually oriented creatures. They rely on sight to identify other members of the same species, food, and potential danger, such as predators. Sea turtles, for example, are so dependent on sight that when researchers blindfolded some of them, the animals were unable to find their way back into the water.

Research also shows that turtles not only can perceive colors, but that certain colors -- red, orange and yellow -- seem to be the most appetizing to them. When they see an object in one of those shades, they display "investigative behavior," which suggests that they're checking it out to see if they want to eat it, according to Turtles: An Extraordinary Natural History 245 Years in the Making.
