Do Alligators Take Care Of Their Young?

Mother alligators usually care for their young until they are about the age of 2.  The reproduction process in alligators and the way in which they care for their young is quite interesting.

Mating season for alligators occurs from mid April through May.  To attract females, males display behaviors such as slapping their heads on the water and producing a deep rumbling bellow.  Once a male and female pair up, they will swim together, touch each other’s snouts, and blow bubbles.  Mating takes place in the water and when it is completed the male disperses and the female is then left to search for a place to build a nest to lay her eggs.

Female alligators construct a nest by using their entire bodies and tail to clear an area.  They use their jaws to gather and drag vegetation, and their hind legs are used to dig the hold in the mound for the eggs.  After completing the nest, the female alligator can be found depositing all of her eggs (usually ranges anywhere from 20 to 50 eggs) at once and covers them up with more vegetation for incubation.

The female may move vegetation around in order to keep the eggs at a fairly constant temperature.  The female alligators stay near the nest during the incubation period and actively defend it from predators.  Raccoons are a common predator when it comes to alligator eggs.  Females may be aggressive towards humans that come near the nest.  They may be seen display behaviors such as hissing and charging intruders, it is for this reason that alligator nests should best be avoided and not approached for any reason.

An alligator’s eggs usually incubate for about 65 days.  During this time the embryos develop and their sex is determined based upon the temperature in which they were incubated at. Once incubation is complete and the hatchlings are ready to emerge from their eggs, they emit a “yerping” sound.  This signals the female that the eggs are about to hatch so she carefully opens the nest.  The hatchlings can then be found tearing through the leathery eggs with an egg tooth that they are equipped with.  This egg tooth is located on the tip of their snout and will fall off after the alligator is a few days old.  The mother alligator can also help the hatchlings emerge from their eggs by rolling the eggs between her tongue and palate.  This helps to ensure that all of the eggs hatch at the same time.  Hatchlings typically emerge from their eggs and then stay near the nesting site for a couple of years where the mother alligator helps care for them until this time.
