Reptilian Incubation
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.
Alligators and crocodiles may nest very much like birds do.
