Predators are raccoons, opossums, and large birds.
They occasionally eat their own. The young remain vulnerable for the 1st year. Dens are built under the lagoon banks. The entrance is 1 to 2 feet under the water surface. The alligators spend the cold months in their dens emerging to sun themselves on the banks when the air temperature is warmer than the water.
