Does embryonic behavioral thermoregulation enhance thermoregulatory capacity of turtle hatchlings?

We found that embryonic behavioral thermoregulation could not enhance the thermoregulatory capacity of turtle hatchlings. Our study is not only the first to provide experimental evidence regarding the impact of embryonic behavioral thermoregulation on offspring thermoregulation but also falsifies the play behavior hypothesis that suggests thermotaxis by embryos allows them to practice thermoregulatory tactics at later life stages.
