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.
The scales of all reptiles have an epidermal component (what one sees on the surface), but many reptiles, such as crocodilians and turtles, have osteoderms underlying the epidermal scale. Such scales are more properly termed scutes. Snakes, tuataras and many lizards lack osteoderms. All reptilian scales have a dermal papilla underlying the ...
Box turtles require an enclosed outdoor location, consistent sun exposure and a varied diet. Without this, a turtle's growth can be stunted and its immune system weakened. Finding box turtles in the wild and taking them as pets, even for a short period, can have detrimental effects. Box turtles want to stay within the area where they were hatched.
The age of a growing box turtle in the wild cannot be accurately estimated by counting the growth rings on the scutes; Their growth is directly affected by the amount of food, types of food, water, illness, and more. Box turtle eggs are flexible, oblong and are (depending on the taxon) on average 2–4 cm long weighing 5-11 g.
A distinguishing characteristic of the genus is the secondary division of the abdominal scutes (the middle pair of scutes in the plastron) due to the development of the plastral hinge as the turtle matures. It eventually leads to the formation of small triangular additional scutes between the abdominal and pectoral scutes. [17]
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.
A scute (/ s k j uː t / ⓘ) or scutum (Latin: scutum; plural: scuta "shield") is a bony external plate or scale overlaid with horn, as on the shell of a turtle, the skin of crocodilians, and the feet of birds.
Like other box turtles, the Florida box turtle has a narrow and highly domed shell with a hinged plastron that allows it to close its shell tightly. However, the Florida box turtle is different in appearance from the other subspecies of Terrapene carolina. Its carapace has a distinct pattern of yellow stripes that make it easily identifiable ...
