Here's why:
* Temperature-Dependent Sex Determination (TSD): These reptiles exhibit TSD, where the temperature during the incubation period dictates the sex of the offspring.
* Different Species, Different Thresholds: The specific temperatures that determine male or female development vary between species. Some species have a narrow range, while others have a broader range.
* Not All Reptiles: Not all reptiles have TSD. Some species, like snakes and some lizards, have genetically determined sex.
Examples:
* Sea Turtles: In many sea turtle species, warmer temperatures produce females, while cooler temperatures produce males.
* Crocodiles: For crocodiles, cooler temperatures generally lead to females, while warmer temperatures result in males.
It's important to note: Temperature isn't the only factor that can influence sex in reptiles. Some species have a combination of genetic and environmental influences on sex determination.
