Methods of incubation vary widely among the many different kinds of reptiles. Various species of sea turtles bury their eggs on beaches under a layer of sand that provides both protection from predators and a constant temperature for the nest. Snakes may lay eggs in communal burrows, where a large number of adults combine to keep the eggs warm ...
Temperature plays a role in the sex of the hatchlings, with lower-temperature nests producing more males and higher-temperature nests producing more females. This is related closely to incubation time, since clutches laid early incubate during the cool season and have longer incubation periods (producing more males), while eggs laid later ...
Temperature-dependent sex determination (TSD) is a type of environmental sex determination in which the temperatures experienced during embryonic/larval development determine the sex of the offspring. [1] It is observed in reptiles and teleost fish, with some reports of it occurring in species of shrimp.
The embryos develop best at water temperatures between 24 and 30 °C (75 and 86 °F) and hatch in three to five days. L. catesbeianus froglet with tail If the water temperature rises above 32 °C (90 °F), developmental abnormalities occur, and if it falls below 15 °C (59 °F), normal development ceases. [ 18 ]
The temperature within nests that have been monitored by researchers remained a constant 32 °C (90 °F) throughout the incubation period which ranges from 65 to 90 days. [16] The blue iguana's eggs are among the largest laid by any lizard. [16] Individuals are aggressively territorial from the age of about three months onward. [22]
The optimal body temperature for the tuatara is from 16 to 21 °C (61 to 70 °F), the lowest of any reptile. [80] The body temperature of tuatara is lower than that of other reptiles, ranging from 5.2–11.2 °C (41.4–52.2 °F) over a day, whereas most reptiles have body temperatures around 20 °C (68 °F).

After covering the nest, terrapins quickly return to the ocean and do not return except to nest again. The eggs usually hatch in 60–85 days, depending on the temperature and the depth of the nest. Hatchlings usually emerge from the nest in August and September, but may overwinter in the nest after hatching. [37]
These reptiles share the burrows made by the birds, and often stay when the birds are present which helps maintain a higher body temperature. [16] Research has shown that fairy prions enable tuatara to maintain a higher body temperature through the night for several months of the year, October to January (austral spring to summer). [ 16 ]
