The turtle shell is a shield for the ventral and dorsal parts of turtles (the order Testudines), completely enclosing all the vital organs of the turtle and in some cases even the head. [1] It is constructed of modified bony elements such as the ribs, parts of the pelvis and other bones found in most reptiles.

A carapace is a dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron.
Aquatic turtles have flatter, smoother shells that allow them to cut through the water. Sea turtles in particular have streamlined shells that reduce drag and increase stability in the open ocean. Some turtle species have pointy or spiked shells that provide extra protection from predators and camouflage against the leafy ground. The lumps of a ...
The turtle's neck and sides are brown on the tops and yellow on the sides and bottom. [9] The turtle's shell is divided into two sections: carapace and plastron. The carapace is further divided into large plates, or scutes. [20] Typically, 11 or 12 pairs of marginal scutes rim the carapace. [8]

Eastern box turtles have a high, domelike carapace and a hinged plastron that allows total shell closure. Their shell has a middorsal keel that smooths out with age. [5] The carapace can be of variable coloration but is normally brownish or black and accompanied by a yellowish or orangish radiating pattern of lines, spots, or blotches.
The succulent is made up of vines covered in green leaves with white veins, and they look exactly like turtle shells. Though small, its vines grow quickly in a sort of cascading effect, making ...
Trionyx is a genus of softshell turtles belonging to the family Trionychidae. In the past many species in the family were classified in this genus, but today T. triunguis, the African or Nile softshell turtle, is the only extant softshell still classified as Trionyx. The other species still assigned to this genus are only known from fossils.
