Turtle The upper shell of the turtle is called the carapace. The lower shell that encases the belly is called the plastron. The carapace and plastron are joined together on the turtle's sides by bony structures called bridges. The inner layer of a turtle's shell is made up of about 60 bones. It include parts of the backbone and the ribs, meaning the turtle cannot crawl out of its shell.

- Sea turtles are reptiles and a part of the Order Testudines which includes all turtles and tortoises. The most distinctive trait of this group is the protective shell. Like all reptiles, turtles have lungs and scaled skin. The shell is made up of two main parts: the ribs and backbone, and the dermal plates.The ribs and backbone are fused to the dermal plates on the top shell.he most distinctive trait of this group is the protective shell.

- A turtle is an animal in armor. Much of its body lies within a protective shell, which has openings for the turtle's four chunky legs, short tail, and head. When danger threatens, many turtles pull legs, tail, and head into the shell.

- The Softshell Turtles have leathery shells, a type of thick skin rather than the hard scutes that other turtles have. They stay hidden in water most of the time, and use camouflage for protection. They are also quick to bite if necessary.he Softshell Turtles have leathery shells, a type of thick skin rather than the hard scutes that other turtles have.

- On either side of the vertebrals (both left and right) there is a row of scutes, the costals. Many turtles have 4 pairs of costals, or, in other words, 4 costals on the left and 4 on the right (these are also called laterals). All around the outside of the carapace, on its margin, are the marginal scutes.

Leatherback sea turtle The leatherback sea turtle (Dermochelys coriacea), sometimes called the lute turtle or leathery turtle, is the largest of all living turtles and is the fourth-heaviest modern reptile behind three crocodilians.It is the only living species in the genus Dermochelys and family Dermochelyidae.eatherback turtles have the most hydrodynamic body design of any sea turtle, with a large, teardrop-shaped body. A large pair of front flippers powers the turtles through the water. Like other sea turtles, the leatherback has flattened fore limbs adapted for swimming in the open ocean.

Tortoises (/ˈtɔːr.təs.ᵻz/) are a family, Testudinidae, of land-dwelling reptiles in the order Testudines. 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 carapace is fused to both the vertebrae and ribcage, and tortoises are unique among vertebrates in that the pectoral and pelvic girdles are inside the ribcage rather than outside.

- Peeling is a cleaning process most common to turtles that frequently bask. Basking in the sun is a means of raising the turtle's temperature. Anything on the turtle's shell like algae reduces the turtle's ability to absorb heat and slows the turtle in water.

Plastid The plastid (Greek: πλαστός; plastós: formed, molded – plural plastids) is a major double-membrane organelle[1] found in the cells of plants, algae, and some other eukaryotic organisms. Plastids are the site of manufacture and storage of important chemical compounds used by the cell.

Chrysemys picta Painted Turtle The painted turtle has a relatively flat upper shell with red and yellow markings on a black or greenish brown background. Males mature at about 70 to 95 mm plastron (lower shell) length, usually at 3 to 5 years of age.

Shell Problems for Tortoise Keepers (* Note: Some turtles and tortoises are supposed to have soft, leathery, or rubbery shells such as the Pancake Tortoise and Soft-shell Turtles.) Very young tortoises are a bit soft or flexible so they can fit in the egg and so the shell can move as they grow. This often worries keepers, but there is a difference between a young shell and a soft shell. Young tortoise shells are springy, like they are made of a stiff plastic- the plastron may feel a bit springy for some time.

EASTERN PAINTED TURTLEChrysemys picta picta The medium-sized painted turtle can be distinguished by its dark shell, which has olive lines running across the carapace (upper shell), dividing the large scutes (scales). The margin of both the carapace and plastron (bottom shell) have black and red markings. The head, neck, and limbs have yellow stripes.

- Medium to very large turtles with a round (hatchling) to oval (adult) skin-covered flattened carapace without scutes or keeling. In the hand they feel something like wet leather. The carapace (which extends back a good deal further than in our basking species) is flexible, & the posterior lip hangs a bit in some adults. The head has fairly high-set eyes & a long, almost snorkel-like nose giving them a needle-nose or Pinnochio face.

- The Spotted Turtle is a scavenging omnivore that feeds on a variety of plant and animal life. Its diet is known to include aquatic plants, cranberries, tadpoles, salamander larvae, earthworms and numerous species of aquatic invertebrates including crayfish and snails. Prey is typically consumed underwater.any Spotted Turtle populations have become isolated or have declined or disappeared due to habitat loss, road mortality and adverse impacts to wetlands. Fortunately, the species is now protected from collection (or collection is regulated) in the states in which it occurs.

Snapping Turtle The snapping turtle is a large aquatic turtle with a big pointed head, long thick tail, and small plastron (lower shell). Upper shell may be tan, brown, or nearly black, but it is often covered with mud or algae. In young turtles, the upper shell has 3 rows of low keels, but these are less apparent in older individuals.

- Most turtles have shells like houses that they can pull their heads and limbs into. But a sea turtle can't pull into its shell at all. The shells of most kinds of sea turtles are made of bone and cartilage (the same bendable stuff your ears are made of.) These are covered with thin plates called scutes. But the leatherback's shell is different.

- The Critically Endangered hawksbill turtle (Eretmochelys imbricata) has been exploited for thousands of years as the sole source of commercial tortoiseshell. The beautiful carapace is generally streaked and marbled with amber, yellow or brown and often has a strongly serrated edge.

Medellin and Caribbean are Colombiaâs main sex tourism destinations: US According to the mayor, the increase in sex tourists in the city is due to the internationalization of the Colombia’s second largest city. Medellin saw an 87% increase in foreign visits between 2006 and 2011. The State Department maintained Colombia’s classification as top tier in terms of efforts to prevent human trafficking, but highlighted the lack of effective prosecution of child sex tourists.

Do Turtle Shells Peel? A turtle's shell is comprised of about 60 bones; the outside is layered in scutes which are plate-like scales similar to the keratin composition of fingernails. They protect the bones and cartilage of the shell underneath. Turtles do shed pieces of their shell like many other reptiles--but unlike snakes, they aren't shedding their skin. A turtle won't actually leave his shell though because it's fused to the rest of his body. A peeling shell can also indicate disease depending on the type of turtle and its health.

Turtle shell The shell of the turtle is an important study, not just because of the obvious protection it provides for the animal, but also as an identification tool, in particular with fossils as the shell is one of the likely parts of a turtle to survive fossilization.

Tortoiseshell French singing bird box with a case made out of tortoiseshell. Tortoiseshell or tortoise shell is a material produced from the shells of the larger species of tortoise and turtle, mainly the hawksbill sea turtle, which is an endangered species largely because of its exploitation for the material.

- Turtles have evolved with certain survival mechanisms, the most obvious of which is the hard shell that encompasses the turtle and protects it in times of danger. A lesser known defense is what is called sperm retention.
