Full Answer

Alligators above water have similar hearing abilities to birds, lizards and other animals without external ears. An alligator's hearing is equal to a goldfish's, and the anatomy of alligators' ears gives them exceptional hearing while they are submerged underwater. An alligator begins to hear when vibrations travel through its skull to its eardrum. Above and below water, alligators are most sensitive to sounds about 800 Hz, which is the range of the chirps made by hatching baby alligators.

  • Q:

    How do alligators reproduce?

    A:

    Alligators reproduce via internal fertilization, mating at night and eventually laying 35 to 50 eggs in a small pit, which is then covered with a nest of decaying vegetation. About five times as many females are hatched as males after an incubation of 65 days, with the sex of offspring determined by temperature rather than genetic differences. The mother guards the eggs and digs them up as they begin hatching.

  • Q:

    How do alligators mate?

    A:

    According to the Savannah River Ecology Laboratory, alligators use a complex series of underwater bellows, sighs, grunts and other vocalizations to attract mates. Before mating, female alligators prepare soft nests of sticks and vegetation. Each female lays 30 to 50 eggs, deposits them in the nest and guards them during the 65-day incubation period.
