"Turtle is, in zoology, the popular name for any species of the Cheloniidæ. They may be distinguished by their long, compressed, fin-shaped, non-retractile feet, with the toes inclosed in a common skin, from which only one or two claws project. The carapace is broad and much depressed, so that when these animals are on shore, and are turned over on their backs, they cannot regain the natural position. Turtles are marine animals; their pinnate feet and light shell render them excellent swimmers. They sometimes live at a great distance from land, to which they periodically return to deposit their soft-shelled eggs in the sand."—(Charles Leonard-Stuart, 1911)
