During the last weeks of gestation, the female spends less time in the water and smells and scratches at the ground, indicating she is searching for a suitable place to lay her eggs. The female excavates a hole, using her hind legs, and lays her eggs in it. Incubation takes 59 to 112 days.

The other fatal danger is water getting into the body cavity before the sac is absorbed completely and while the opening has not completely healed yet. The sex of red-eared sliders is determined by the incubation temperature during critical phases of the embryos' development. Only males are produced when eggs are incubated at temperatures of , whereas females develop at warmer temperatures. Colder temperatures result in the death of the embryos.

In Australia, breeding populations have been found in New South Wales and Queensland, and individual turtles have been found in the wild in Victoria, the Australian Capital Territory and Western Australia. Red-eared slider turtles are considered a significant threat to native turtle species – they mature more quickly, grow larger, produce more offspring and are more aggressive. Numerous studies provide evidence that red-eared slider turtles can out-compete native turtles for food and nesting and basking sites. Because red-eared slider

Oregon has introduced public education on turtle awareness, safe swerving, and safely assisting turtles across the road. In the West, human-introduced bass, bullfrogs, and especially snapping turtles, have increased the predation of hatchlings. Outside the Southeast, where sliders are native, released pet red-eared slider turtles increasingly compete with painted turtles. In cities, increased urban predators (raccoons, canines, and felines) may impact painted turtles by eating their eggs. Other factors of concern for the painted turtles include over-collection from the wild, released pets introducing diseases or reducing

The diet of red-crowned roofed turtles consists entirely of water plants. They leave the water to thermoregulate by basking in the sun on rocks, logs, and sandbanks. Adult females lay eggs in March and April. The eggs are long by wide. Clutch size varies from 11 to 30 eggs. The large "Batagur" turtles are probably the most threatened freshwater turtles in India. Their populations have now been drastically reduced due to poaching for their meat and shells, accidental

slider ("Trachemys scripta"). Female terrapins can mate with multiple males and store sperm for years, resulting in some clutches of eggs with more than one father. Like many turtles, terrapin have temperature dependent sex determination, meaning that the sex of hatchlings is the result of incubation temperature. Females can lay up to three clutches of eggs/year in the wild, and up to five clutches/year in captivity. It is not known how often they may skip reproduction, so true clutch frequency is unknown. Females may wander considerable distances on land before nesting. Nests are usually laid in sand dunes or scrub

Eggs and young turtles are prey to skunks, raccoons, birds, and fish. Their natural lifespan is 40 to 45 years. The population had been reduced to 200–300 turtles by the 1980s. By 2007, there were estimated to be 400–600 breeding age turtles across 20 ponds. This is due to overhunting by its natural predator the skunk and pollution from herbicides dumped into streams and ponds.

Red-eared sliders are almost entirely aquatic, but as they are cold-blooded, they leave the water to sunbathe to regulate their temperature. Red-eared sliders do not hibernate, but actually brumate; while they become less active, they do occasionally rise to the surface for food or air. Brumation can occur to varying degrees. In the wild, red-eared sliders brumate over the winter at the bottoms of ponds or shallow lakes. They generally become inactive in October, when temperatures fall below .

On land, however, the sea turtles are nearsighted because the lenses in the eyes are spherical and adjusted to refraction underwater. Sea turtles have no external ear and only one ear bone, called the columella. With one ear bone, the turtles can only hear low frequency sounds, from 200 to 700 Hz. Sounds can also be detected through vibrations of the head, backbone, and shell.

Yellow-bellied sliders are capable of interbreeding with other "T. scripta" subspecies, such as red-eared sliders, which are commonly sold as pets. The release of non-native red-eared sliders into local environments caused the state of Florida to ban the sale of red-eared sliders in order to protect the native population of yellow-bellied sliders. Mating takes place in the water. Suitable terrestrial area is required for egg-laying by nesting females, who will normally lay 6–10 eggs at a time, with larger females capable of bearing more. The eggs incubate for 2–3 months and the hatchlings will usually stay with the nest through

Conservationists have warned owners of turtles to not release them into the wild. There are also many states that have passed legislation to control the possession and release of Pond sliders. There are two states that have completely banned the sale of these turtles. Hybridization between yellow-bellied and red-eared sliders is not uncommon where the ranges of the two subspecies overlap.

Before the mid 20th century, it had nearly no human population, but that changed when a market for sea turtle meat and eggs developed. Due to the many turtles that come to Mazunte to lay eggs, by the 1970s, Mazunte was the center of sea turtle hunting in Mexico, with its own slaughterhouse.

Thousands of Olive Ridley turtles arrive en masse to lay their eggs in nearby Escobilla Bay. The nesting season generally begins in May and lasts for several months. Although an endangered species, the turtles come to the beach in large numbers for a few nights after a full moon. These events are called arribadas.

However, because of their high metabolic rate, leatherback sea turtles have a body temperature that is noticeably higher than that of the surrounding water. Turtles are classified as amniotes, along with other reptiles, birds, and mammals. Like other amniotes, turtles breathe air and do not lay eggs underwater, although many species live in or around water. The study of turtles is called cheloniology, after the Greek word for turtle. It is also sometimes called testudinology, after the Latin name for turtles. Differences exist in usage of the common terms "turtle",

The turtles can take up dissolved oxygen from the water using these papillae, in much the same way that fish use gills to respire. Like other reptiles, turtles lay eggs that are slightly soft and leathery. The eggs of the largest species are spherical while the eggs of the rest are elongated.

reproductive functions. Some dimorphism exists between males and females. Red-eared slider young look practically identical regardless of their sex, making it difficult to determine their sex. However, there is another method to determine their sex, by inspecting the markings under their carapace. These markings will fade as the turtles age. It is much easier to distinguish the sex of adults, as the shells of mature males are smaller than those of females. Male red-eared sliders reach sexual maturity when their carapaces' diameters measure and females reach maturity when their carapaces measure 15 cm. Both male and females reach sexual maturity

These turtles often fight with native species for food, habitats, and other resources. Eventually they bully many native species out of basking sites. Basking being areas where there is sunlight and warmth for the species. When basking it is common that pond sliders will bask on birds nests, therefore killing the eggs.

Large numbers of eggs are deposited in holes dug into mud or sand. They are then covered and left to incubate by themselves. Depending on the species, the eggs will typically take 70–120 days to hatch. When the turtles hatch, they squirm their way to the surface and head toward the water.

They will have an average of 50 eggs laid each time in a clutch, while other sea turtles may lay up to 100-150 eggs in a clutch. The eggs are about 55mm long within these clutches. The sex of the flatback turtle hatchling is determined by the temperature of the sand that the egg is in. If the temperature is below 29 °C then the hatchling will be a male, and if the temperature is above this 29 °C it will be female.

The Jamaican slider is listed as Vulnerable in the 2007 IUCN Red List but is not currently listed under CITES. The populations in both Jamaica and the Bahamas are largely effected by introduced predators to those islands. These include

The comb and wattles are large and blood-red; the comb has 5–6 points. The ear-lobes are creamy yellow with some red veining. Average weight is for cocks, for hens. The eggs are white and should weigh 58–70 g. The Valdarnese is raised principally for its meat, which is firm and tasty, and notably different from that produced by intensive farming methods. Approximately 6000 birds are slaughtered per year. Hens tend to become broody, and are poor layers; they lay an average of 135 eggs per year.

The whole process takes thirty to sixty minutes. She then returns to the ocean, leaving the eggs untended. Females may lay 1–8 clutches in a single season. Female sea turtles alternate between mating in the water and laying their eggs on land. Most sea turtle species nest individually. But ridley sea turtles come ashore en masse, known as an "arribada" (arrival). With the Kemp's ridley sea turtles this occurs during the day. Sea

can occasionally be found in shallow water. The painted wood turtle feeds on fruit, insects, and worms. Their diet should consist of 60% leafy greens, 30% protein, and 20% fruits and vegetables. Along with a varied diet, they require additional calcium to insure healthy shell growth. Unlike aquatic turtles, the painted wood turtle doesn't require water in order to swallow its food. Painted wood turtles are oviparous. Females lay 3-5 eggs at a time. Eggs at low temperatures can be dormant early stages, and can sleep for some time at low temperatures, when the temperature returns to normal incubation can

Leatherback sea turtles swim seasonally to lay eggs on Thai Mueang Beach in the park. Thailand was once a sanctuary for leatherback turtles. Monitoring between 2003–2013 at Thai Mueang Beach found turtles laid 2,678 eggs there and 1,574, or 58.7 percent survived. The species is disappearing. Irresponsible trawler fishing is one of the factors to blame. Property development on the beach has kept the turtles away. Another factor is the traditional belief that consuming turtle

strong and far reaching ocean currents which can move pollution to great distances from its derivation. Breeding season is in particular a dangerous time for sea turtles due to the pollution of beach nesting sites. Contamination of their diet can lead to disruption of digestion as well as physical injury of the sea turtles’ digestive tracts. The nesting of female sea turtles is often deterred due to the potential of oily effluence. If the female does lay eggs, the development of the eggs is still at risk due to either oil in the sand or contamination from the mother turtle

Some species have distinctive yellow striping along the sides of the head and neck. The musk turtles are so named because they are capable of releasing a foul-smelling musk from glands under the rear of their shells when disturbed. They are native to North America and South America. All members of the family are carnivorous, feeding on crustaceans, aquatic insects, mollusks, annelids, amphibians, small fish, and sometimes carrion. Kinosternids lay about four hard-shelled eggs

Distances of migration are recorded to range between 1233 and 2143 km and are performed over various time periods. They come to the Galápagos primarily to nest and only the females come ashore and lay eggs; the males stay submerged for most of their lives.

The painted turtle has a very similar appearance to the red-eared slider (the most common pet turtle) and the two are often confused. The painted turtle can be distinguished because it is flatter than the slider. Also, the slider has a prominent red marking on the side of its head (the "ear") and a spotted bottom shell, both features missing in the painted turtle. The painted turtle hunts along water bottoms.

maturity at 18 or more years, and males around 16 years. They lay their eggs late in the dry season on sandy river banks. When the offspring are fully developed, they will stay inside the eggs in hibernation until conditions are suitable for emergence. Hatching may be triggered when the eggs have been flooded with water or by a sudden drop in air pressure signaling an approaching storm. Using environmental triggers, along with vibrations created by other hatching turtles in the same clutch, gives a better chance for survival. Using a universal trigger rather than simply waiting for incubation to

As with other turtles, tortoises, and box turtles, individuals that survive their first year or two can be expected to live generally around 30 years. But they are an infection risk, and when they mature they can inflict painful bites, which results in many being dumped into the wild with negative ecological, social and economic impacts. Reptiles are asymptomatic (meaning they suffer no adverse side effects) carriers of bacteria of the genus "Salmonella". This has given rise to justifiable concerns given the many instances of infection of humans caused by the

On occasion, a male may appear to be courting another male, and when kept in captivity may also show this behaviour towards other household pets. Between male turtles, it could be a sign of dominance and may preclude a fight. Young turtles may carry out the courtship dance before they reach sexual maturity at five years of age, but they are unable to mate. After mating, the female spends extra time basking

painted turtles were the second most popular pet turtles after red-eared sliders in the early 1990s. As of 2010, most U.S. states allow, but discourage, painted turtle pets, although Oregon forbids keeping them as pets, and Indiana prohibits their sale. U.S. federal law prohibits sale or transport of any turtle less than , to limit human contact to salmonella. However, a loophole for scientific samples allows some small turtles to be sold, and illegal trafficking also occurs.

desert-dwelling species also feature yellow-red tones. Camouflage ranges from bands and stripes to splotches, speckles, and circles, and can change as the creature matures, with juveniles sometimes being brighter than adults. Like most lizards, goannas lay eggs. Most lay eggs in a nest or burrow, but some species lay their eggs inside termite mounds. This offers protection and incubation; additionally, the termites may provide a meal for the young as they hatch. Unlike some other species of lizards, goannas do not have the ability to regrow limbs or tails. The name goanna derived from iguana, since early European bush settlers

The head, legs, and tail are green with fine, irregular, yellow lines. The whole shell is covered in these stripes and markings that aid in camouflaging an individual. Turtles also have a complete skeletal system, with partially webbed feet that help them to swim and that can be withdrawn inside the carapace along with the head and tail.

December. Sea turtles return to the beaches on which they were born to lay their own eggs. The reason for returning to native beaches may be that it guarantees the turtles an environment that has the necessary components for their nesting to be successful. These include a sandy beach, easy access for the hatchlings to get to the ocean, the right incubation temperatures, and low probability of predators that may feed on their eggs. Over time these turtles have evolved these tendencies to return to an area that has provided reproductive success for many generations. Their ability to return to

Outbreaks in multiple states and fatalities in children, associated with handling salmonella-infected turtles, have been recorded in the USA. Salmonella can also spread to humans when turtles contaminate drinking water. There have been varying degrees of action by state governments to date, ranging from ongoing eradication efforts by the Queensland government to very little action by the government of New South Wales. Experts have ranked the species as high priority for management in Australia and are calling for a national prevention and eradication strategy, including a concerted education

freshwater Arrau turtle ("Podocnemis expansa") researchers examined the effects of nest relocation. They discovered that clutches of this freshwater turtle that were transplanted to a new location had higher mortality rates and more morphological abnormalities compared to non transplanted clutches. However, in a study of Loggerhead turtles ("Caretta caretta"), Dellert et al. found that relocating nests at risk of inundation increased the success of eggs and hatchlings and decreased the risk of inundation. Most sea turtle mortality happens early in life. Sea turtles usually lay around one hundred eggs at a time, but on average only one of the eggs

The eggs are laid on the underside of corn plant leaves near the midvein. Around 90% of the eggs are laid on the leaf just below the primary ear leaf, and an equal number of eggs are laid above and below this leaf, with a slight bias towards the lower leaves. The egg masses are all laid within five leaves of the central ear leaf. Brood sizes range from 15 to 30

Leptocorisa oratoria Leptocorisa oratoria, the rice ear bug, is an insect from the family Alydidae, the broad-headed bugs. This species is commonly confused with "Leptocorisa acuta", a similar and closely related species, called the rice earhead bug. It has a slender body, around 2 cm length, with long legs and a long proboscis. It is yellow-brown in color. When disturbed, the bug gives off an unpleasant smell in defense. Females lay around 100-200 eggs on the leaves of the rice plant ("Oryza sativa"). The eggs hatch into green-colored nymphs, which gradually turn brown as they grow into adults. Rice ear

While the queen in a "T. angustula" hive will lay most of the eggs in a brood, some workers also have the ability to develop and lay eggs. Unlike reproductive eggs, these worker eggs do not have a reticulum and thus develop into males.

she continues to care for them for another year. Alligators are very particular about their nesting sites and will abandon a site if things go wrong. Cobras use leaves and other debris to build nests in which they lay eggs that both sexes guard. They carry the vegetation to the nest site by kinking their necks. Sea turtles dig a hole in the sand above the high tide line in which they lay their eggs. They then cover the soft eggs to protect them from the sun and predators and leave. From the fossil record, it is known that many,

Sea turtles fly through the water, using the up-and-down motion of the front flippers to generate thrust; the back feet are not used for propulsion but may be used as rudders for steering. Compared with freshwater turtles, sea turtles have very limited mobility on land, and apart from the dash from the nest to the sea as hatchlings, male sea turtles normally never leave the sea. Females must come back onto land to lay eggs. They move very slowly and laboriously, dragging themselves forwards with their flippers. Turtles are thought to

Females will come ashore to lay their eggs on sandy beaches during the nesting season. Sea turtles migrate to reach their spawning beaches, which are limited in numbers. Living in the ocean therefore means they usually migrate over large distances. All sea turtles have large body sizes, which is helpful for moving large distances. Large body sizes also offer good protection against the large predators (notably sharks) found in the ocean. It takes decades for sea turtles to reach sexual maturity. Mature turtles may migrate thousands of miles to reach breeding sites. After mating at sea, adult female sea turtles

otters ("Enhydra lutris"), whales (Order: Cetacea), dolphins (Suborder: Odontoceti), seals (Clade: Pinnipedia), and manatees ("Trichechus" spp.). Sea otters are among the most susceptible of marine mammals, because the oil interrupts their ability to trap air within their fur for insulation. Other species, such as marine turtles (Superfamily: Chelonioidea), fish, and shellfish can also be adversely affected by oil spills. Sea turtles may become affected when they return to shores to lay eggs. Fish are impacted by the oil that is taken in by their gills and digestive system.

In addition, eggs may be jeopardized by flooding, frost, or various developmental problems. It is unknown how gender is determined in bog turtles. Baby bog turtles are about long when they emerge from their eggs, usually in late August or September. Females are slightly smaller at birth, and tend to grow more slowly than males. Both genders grow rapidly until they reach maturity. Juveniles almost double in size in their first four years, but do not become fully grown until five or six years old.

alligators and their larger cousins, alligator snapping turtles. Large, old male snapping turtles have very few natural threats due to their formidable size and defenses, and tend to have a very low annual mortality rate. These turtles travel extensively over land to reach new habitats or to lay eggs. Pollution, habitat destruction, food scarcity, overcrowding, and other factors drive snappers to move; it is quite common to find them traveling far from the nearest water source. Experimental data supports the idea that snapping turtles can sense the Earth's magnetic field, which could also be used for such movements (together with
