A Turtle's ShellA Turtle's Shell A turtle's shell consists of two layers. The inner layer is made up of bony plates and is actually part of the skeleton. Most turtles that live on land have a high, domed shell. Those that live in water have a flatter, more streamlined shell.
Leatherback Sea Turtle (Dermochelys coriaces)Leatherback Sea Turtle (Dermochelys coriaces) The largest sea turtle in the world averages 4 to 6 feet in length and weighs between 600 and 1,100 pounds. The leatherback gets its name from the fact that, instead of a hard shell, it has a leathery carapace composed of a mosaic of small bones covered by a firm rubbery skin.
European Pond Turtle (Emys orbicularis)European Pond Turtle (Emys orbicularis) Although this species exhibits variations in coloration throughout its range, there is usually some light speckling on a dark background color. It is found in southern and central Europe, into northwestern Africa and humid areas of the Middle East and Central Asia, as far east as the Aral Sea.
Ornate Box Turtle (Terrapene ornata)Ornate Box Turtle (Terrapene ornata) This turtle's shell has a fancy look to it. Each shell segment (scute) has a radiating pattern of yellow lines on a dark brown background.
