Where is the carapace of a turtle?

The carapace is the dorsal (back), convex part of the shell structure of a turtle, consisting of the animal's ossified ribs fused with the dermal bone. The spine and expanded ribs are fused through ossification to dermal plates beneath the skin to form a hard shell.

What is carapace crab?

What is a carapace on a spider?

Carapace: A hardened plate (sclerite) covering the upper (dorsal) portion of the cephalothorax; see also Carapace. Carpoblem: The principal tibial apophysis on the male pedipalp; also just called the tibial apophysis.

What is carapace length?

Carapace length is the straight line measurement from the rear of the eye socket parallel to the center line of the carapace to the posterior edge of the carapace. ... Carapace length is defined as the length between the posterior mid-dorsal margin to the posterior-most part of the eye-stalk orbit.

Is a turtle an endoskeleton?

Like their aquatic cousins, the turtles, tortoises are shielded from predators by a shell. The top part of the shell is the carapace, the underside is the plastron, and the two are connected by the bridge. The tortoise has both an endoskeleton and an exoskeleton. ... Tortoises are generally reclusive and shy.

Do beetles have a carapace?

What bones comprise the turtle carapace?

Anatomy of Turtle and Tortoise Shells

The carapace is the fusion of about 50 bones - the ribs and vertebrae. The plastron is the fusion of bones including the clavicles (collar bones), bones between the clavicles, and portions of the ribs. A bony bridge joins the carapace and the plastron along the side of the turtle.
