In Pleurodires the posterior pelvis is also part of the carapace, fully fused with it. This is not the case in Cryptodires which have a floating pelvis. [2] [3] The anterior bridge strut and posterior bridge strut are part of the plastron. On the carapace are the sutures into which they insert, known as the Bridge carapace suture. [4]
Diagram of a prawn, with the carapace highlighted in red. 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.
The carapace is leathery and pliable, particularly at the sides. The central part of the carapace has a layer of solid bone beneath it, as in other turtles, but this is absent at the outer edges. Some species also have dermal bones in the plastron, but these are not attached to the bones of the shell. The light and flexible shell of these ...
Typically, a turtle has 38 scutes on the carapace and 16 on the plastron, giving them 54 in total. Carapace scutes are divided into "marginals" around the margin and "vertebrals" over the vertebral column, though the scute that overlays the neck is called the "cervical". "Pleurals" are present between the marginals and vertebrals. [20]
The generic name Sternotherus is Greek meaning hinged breast or chest, referring to the hinged plastron. [3] The trivial names, or specific epithets include: carinatus – Latin for keeled in reference to the shape of the carapace; [4] depressus – Latin for pressed down or low also referring to the shape of the carapace; [5] intermedius – Latin for intermediate, historically believed to be ...
Typically, 11 or 12 pairs of marginal scutes rim the carapace. [8] Five vertebral scutes run down the carapace's midline, while five pairs of costal scutes border them. [21] The nuchal scute is located at the base of the head. [21] The carapace connects to the plastron by three pairs of inframarginal scutes forming the bridge of the shell. [21]
Among the 14 people killed in the New Orleans attack: a warehouse manager, an account executive, an aspiring nurse and two loving parents.
A female has a carapace length of 16.5–35.6 cm (6.5–14.0 in) compared to a carapace length of 11.4–17.8 cm (4.5–7.0 in) for males. [6] Additionally, the female smooth softshell turtle is usually brown or olive-colored with irregular dark brown blotches, while the carapace of males and juveniles is a brown or grayish color with dark dots ...
