2011. Although it was originally thought that alligators never stop growing, studies have now found that males stop growing at around the age of 43 years, and females stop growing at around the age of 31 years.[46]. (Erickson, et al., 2003; Lance, 1989; Neill, 1971; Ouchley, 2013). (Dinets, 2013a; Dinets, 2013b; Higgs, et al., 2002; Leitch, 2012; Riede, et al., 2011). In mature males, most specimens grow up to about 3.4m (11ft 2in) in length, and weigh up to 360kg (790lb),[7] while in females, the mature size is normally around 2.6m (8ft 6in), with a body weight up to 91kg (201lb). They are similar to other dogs, but they have some unique behaviors. that region of the Earth between 23.5 degrees North and 60 degrees North (between the Tropic of Cancer and the Arctic Circle) and between 23.5 degrees South and 60 degrees South (between the Tropic of Capricorn and the Antarctic Circle). One of the most interesting behavioral adaptations of spitting cobras is their intimidating demeanor. 1. [3], They inhabit swamps, streams, rivers, ponds, and lakes. [85][86] As they grow, American alligators gradually expand to larger prey. How Often Do Alligators Attack Humans in Florida? Domestic American alligators range from long and slender to short and robust, possibly in response to variations in factors such as growth rate, diet, and climate. This experiment had not been, at the time of the paper published, replicated in any other crocodilians, and the same laboratory was able to measure a greater bite force of 16,414N (1,673.8kgf; 3,690lbf) in saltwater crocodiles;[53][54] notwithstanding this very high biting force, the muscles opening the American alligator's jaw are quite weak, and the jaws can be held closed by hand or tape when an American alligator is captured. A lone American alligator was spotted for over 10 years living in a river north of Atlanta, Georgia. This differs from Nile crocodiles, which lay their eggs in pits. American alligators can cause harm or death to humans. The sprawling of American alligators and other crocodylians is not similar to that of salamanders and lizards, being similar to walking. Dinets, V. 2013. Alligator holes are an oasis during the Everglades dry season, so are consequently important foraging sites for other organisms. But recent studies are beginning to give us a better understanding of these fascinating animals. It is more difficult for the alligator to communicate through waterborne signals. You may still see alligators moving around during cold weather, but they are not as active as they are during other times of the year. One interesting aspect of alligator biology is that even though they do not hibernate, they undergo periods of dormancy when the weather becomes cold. On the on-line US federal list they are still listed as threatened, but as other research provides, they are no longer a listed species. The Chinese alligator likely descended from a lineage that crossed the Bering land bridge during the Neogene. These states produce a combined annual total of some 45,000 alligator hides. Sea turtles are strong swimmers. While ADW staff and contributors provide references to books and websites that we believe are reputable, we cannot necessarily endorse the contents of references beyond our control. a wetland area that may be permanently or intermittently covered in water, often dominated by woody vegetation. An additional report of alligator attacks showed a total of 376 injuries and 15 deaths recorded all from 1948 to 2004, leading this to an increase of the alligator population.
