Wild Facts About The American Alligator
American Alligators Are Not To Be Trifled With
- DANGEROUS! Stay away from these reptiles!
- While seldom aggressive unless provoked, adult American Alligators are large, dangerous predators that can easily overpower and drown an adult human.
- Under no circumstances should the average person deliberately grab, touch, attempt to pick up, feed, or otherwise disturb these reptiles.
- Exercise extreme caution when in areas they inhabit, especially at or near the edges of bodies of water.
- The presence of little alligators often indicates the presence of much larger adults.
- Author’s Note: Very few animals scare me, but adult American Alligators manage the feat. I took the photo of the North Carolina pond featured in the image gallery below with a telephoto lens from inside my car, with the doors locked and my foot on the gas. I stay far away from the waters’ edge anywhere in southeastern United States, from North Carolina south, and recommend everyone do the same.
- The American Alligators featured in the image gallery live in the Florida Everglades National Park—a tremendous natural area and a true national treasure.
- I took all photos with a telephoto lens from a very respectful distance, while my husband kept careful watch on our surrounding area.
- American Alligators are truly magnificent animals, worthy of our admiration, respect, and protection. For the most part, they pose no direct threat as they don’t seem to care much about what humans are doing around them. At the same time, they are extremely powerful predators. No matter what nonsense you see on TV—take these reptiles seriously and give them the space and respect they deserve.

Hunters Perfected
- American Alligators are active predators that submerge and either float motionlessly until prey wanders too close or slowly swim towards unwary prey.
- Their broad snouts give them flat profiles, so that only their eyes and nostrils protrude above the surface while water hides the rest of their large bodies.
- Extremely powerful biting jaws come equipped with large, widely-spaced, conical teeth perfectly adapted for grabbing and holding struggling prey.
- A large tooth on each side of the lower jaw fit into a socket in the upper jaw when the mouth is closed.
- Only the top teeth are visible when the reptiles close their jaws (Grigg and Kirshner 2015).
- When submerged, special membranes slide over their eyes, and valves close off their ear holes and nostrils.
- These very large reptiles feed on prey taken in and under the water, like fish, turtles, frogs, and snakes, as well as prey taken from the land along the waters’ edge, like birds and mammals.
- Adult American Alligators are large enough to take prey as large as White-Tailed Deer (Odocoileus virginianus).
- Alligator teeth are poorly adapted for ripping or chewing.
- American Alligators swallow small prey whole in a series of gulps.
- They stash large prey to decay and soften for several days. After a few days, they return to feed.
- Alligators twist off chunks of rotting flesh by clamping their teeth into the prey and spinning their bodies with their powerful limbs and tail.

Mother Alligators Have No Sense Of Humor
- After mating in the spring, female American Alligators s lay 25-60 hard-shelled eggs in nest mounds made of mud, leaves, and rotting organic vegetation (Behler and King 2020).
- Alligator nests can be as large as 5 – 7 feet (1.5 – 2.1 meters) wide and 1.5 – 3 feet (46 – 91 cm) tall.
- The rotting vegetation warms the eggs and helps the embryos develop.
- Hatchling sex is determined by the temperature in the nest (see “temperature-dependent sex determination“):
- Low incubation temperatures result in female hatchlings
- Higher incubation temperatures result in male hatchlings
- Hatchling sex is determined by approximately halfway through an embryo’s incubation (Grigg and Kirshner 2015).
- Females guard their nests, eggs, and hatchlings aggressively and can be especially dangerous during breeding season.


Even The Mighty Can Fall
- Adult American Alligators have no natural predators beyond larger alligators.
- However, in Florida, American Alligators are threatened by invasive Burmese Pythons, which are the only animals powerful enough to kill full-sized alligators.
- The pythons wrap their body coils around the alligators and constrict; the alligators drown if attacked in water or suffocate if attacked on land.
- The eggs and hatchlings are much more vulnerable to predators. These can include:
- Virginia Opossums (Didelphis virginiana),
- Bobcats (Lynx rufus),
- Raccoons (Procyon lotor)
- In one study, raccoons were the primary nest predator, responsible for 42.8 % of nest predation (Rainwater et al. 2024, https://doi.org/10.3390/ani14040620)
- American Alligators may serve as food for some parasites including:
- Dracovermis occidentalis, a trematode (parasitic flatworm) found to have infected one alligator in Alabama (Dutton et al. 2024, https://doi.org/10.1007/s00436-024-08339-2)
- Blood-sucking leeches (Richardson et al. 2017, https://doi.org/10.3897/zookeys.667.10680).
