Neonate Care

 

Mother alligator will will attend her brood well after they hatch, perhaps a year or longer, providing protection from predators, which include large fish, birds, racoons, bears, bobcats, other alligators, and other large animals that eat meat. It has been reported that the mother may eat her young after a year or so if they do not leave and establish their independence. This behavior seems to be nature's way of protecting the line of progeny, as the growing alligator competes for immediate resources with the mother and younger siblings.

 

The young will remain in proximity to the mother, and will even bask on the top of her body as she floats in the water. Only about three of the average of 30-35 babies that hatch each year will reach adulthood, due to heavy predation upon them. Thus, mother's guardianship behavior is crucial to the survival of the species.

 

Please refer to the "Reproduction" section for a discussion of the maternal care that occurs before hatching.

Note the larger youngsters present; these are likely from the previous year's hatchings, who choose to remain near their parent. They may also be young from another alligator, and have 'adopted' this maternal guardian.
