Turtles are reptiles of the order Testudines characterized by a special bony or cartilaginous shell developed from their ribs and acting as a shield. “Turtle” may refer to the order as a whole or to fresh-water and sea-dwelling testudines. The order Testudines includes both extant and extinct species.
“Behold the turtle. He makes progress only when he sticks his neck out.” —James Bryant Conant
