Chinese alligators are ectothermic; they rely on the outside environment to regulate their body temperatures; their adaptations are outwardly focused on staying comfortable:
Burrow Builders: Spending the winter in elaborate dens or caves allow Chinese alligators to go dormant when the weather is too cold.
Basking the Day Away: Chinese alligators spend a lot of time just laying around in the sun when they first emerge in the spring. While this might appear non-productive, they are raising their body temperature by basking.
Hot Baby, Cold Baby: The sex of Chinese alligators is determined by temperature during incubation. At hotter temperatures, the babies are male, and at colder temperatures the babies are female.
