This four-page article from the Office of Naval Research is a great introduction to the characteristics, adaptation, and current research about this endangered species, which first appeared in the Triassic Period. Scientists are testing the effect of man-made sounds on green turtle behavior. Concluding the information is a brief quiz, including a question about how green turtles got their name.
