Protection: Perhaps one of the most crucial roles played by the turtle and tortoise skeleton is providing effective protection from predators. Their shell serves as armor shielding vulnerable body parts from potential harm.

The skeletal framework of turtles and tortoises consists mainly of bones, which are connected by joints called sutures. These sutures allow for limited movement between certain bones while maintaining stability. One example illustrating this intricate interplay can be seen in the carapace, or upper portion of the shell, where several fused ribs form a solid protective shield encasing vital organs such as the heart and lungs.Some live their whole lives at sea while others spend most of their time on land. Their bodies and skeletons have evolved in certain ways to deal with the demands and way of life that water or land offers. And if you liked this, we've got way more animal facts here! Including these cool cheetah facts and these awesome octopus facts! 1. The Name For A Group Of Tortoises Is A 'Creep' Should an area of your tortoise’s shell start to develop any whitish patches or becomes abnormally discoloured, this is a further indication of an infection. This may have arisen following a relatively minor injury.

Septicemic cutaneous ulcerative disease (SCUD) or "shell rot" causes ulceration of the shell. [48] This is caused by bacteria or fungi entering through an abrasion, and poor animal husbandry. The disease progresses to a septicemic infection causing the degradation of the liver and other organs. [49] Pyramiding [ edit ]

By recognizing these distinctive characteristics, we gain a deeper appreciation for the diverse adaptations within this fascinating group of reptiles. Moon, J. C.; McCoy, E. D.; Mushinsky, H. R.; Karl, S. A. (2006). "Multiple Paternity and Breeding System in the Gopher Tortoise, Gopherus polyphemus". Journal of Heredity. 97 (2): 150–157. doi: 10.1093/jhered/esj017. PMID 16489146. Tortoises all look pretty much the same for most of their life - only when they reach sexual maturity can you tell them apart. Female tortoises are generally smaller with shorter tails, and the bottom of their shell is usually flatter. Now you know! 13. They Are A Type Of Turtle A stem-turtle from the Middle Triassic of Germany, some 240 million years ago, Pappochelys, has more distinctly broadened ribs, T-shaped in cross-section. [35] They vary in shape along the spine. [42] Most species of tortoises lay small clutch sizes, seldom exceeding 20 eggs, and many species have clutch sizes of only 1–2 eggs. Incubation is characteristically long in most species, the average incubation period are between 100 and 160.0 days. Egg-laying typically occurs at night, after which the mother tortoise covers her clutch with sand, soil, and organic material. The eggs are left unattended, and depending on the species, take from 60 to 120 days to incubate. [11] The size of the egg depends on the size of the mother and can be estimated by examining the width of the cloacal opening between the carapace and plastron. The plastron of a female tortoise often has a noticeable V-shaped notch below the tail which facilitates passing the eggs. Upon completion of the incubation period, a fully formed hatchling uses an egg tooth to break out of its shell. It digs to the surface of the nest and begins a life of survival on its own. They are hatched with an embryonic egg sac which serves as a source of nutrition for the first three to seven days until they have the strength and mobility to find food. Juvenile tortoises often require a different balance of nutrients than adults, so may eat foods which a more mature tortoise would not. For example, the young of a strictly herbivorous species commonly will consume worms or insect larvae for additional protein. [12]
