American alligators are apex predators and consume fish, amphibians, reptiles, birds, and mammals. The folds result in greater surface area for the nutrients to be absorbed through. [89] Rarely, American alligators have been observed killing and eating bobcats, but such events are not common and have little effect on bobcat populations. "Gators" has been the nickname of the University of Florida's sports teams since 1911. [78], Fish and other aquatic prey taken in the water or at the water's edge form the major part of American alligator's diet and may be eaten at any time of the day or night. Some 23 dead whales have washed ashore along the East Coast since early December, including 12 in New Jersey and New York. On average, it is the largest species in the family Alligatoridae, with only the black caiman being possibly longer. States began monitoring their American alligator populations to ensure that they would continue to grow. Louisiana has the largest alligator population. [47], Dorsally, adult American alligators may be olive, brown, gray, or black. [136] The mascot stuck, and was made official in 1911, perhaps because the team captain's nickname was Gator.

[21] [22] A small population is also found in Tamaulipas, in Mexico. [26] Farther west, in Louisiana, heavy grazing by coypu and muskrat are causing severe damage to coastal wetlands. By 1960, however, alligators had been completely eliminated from much of their former range. [53] There is also fluctuation in the level of bacterial taxa populations in the alligator's microbial community between seasons which helps the alligator cope with different rates of feeding and activity. [118] They are preyed on by large fish, birds, raccoons, Florida panthers, and adult American alligators. 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. [23] If the size of this animal was correct, it would have weighed about 1,000kg (2,200lb). [38] Another form of male display is a loud head-slap. Although no valid records exist about its date of birth, as of 2012, it was in its 80s and possibly the oldest alligator living in captivity. Although gators live in these areas, some states have few geographical locations where one can find alligators. The Gator Bowl is a college football game held in Jacksonville annually since 1946, with Gator Bowl Stadium hosting the event until the 1993 edition. An alligator, or just gator, is a large reptile in the Crocodilia order in the genus Alligator of the family Alligatoridae. The largest populations occurred in the broad marl prairies to the east and west of the southern ridge and slough and to the mangrove estuaries inhabited by crocodiles. This may encourage people to approach alligators and their nests, which can provoke the animals into attacking. 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.[44]. Unlike most other land vertebrates, American alligators increase their speed through the distal rather than proximal ends of their limbs.

The American alligator ( Alligator mississippiensis ), sometimes referred to colloquially as a gator or common alligator, is a large crocodilian reptile native to the Southeastern United States. F. Wayne King, John Thorbjarnarson and Carlos Yamashita. The two states that have the most gators are Florida and Louisiana. [71] When the water begins to freeze, American alligators go into a period of brumation; they stick their snouts through the surface, which allows them to breathe above the ice,[66] and they can remain in this state for several days. [57][58] The Aquarium of the Americas in New Orleans has leucistic alligators found in a Louisiana swamp in 1987. Nests constructed on leaves are hotter than those constructed on wet marsh, so the former tend to produce males and the latter, females. Fish and Wildlife, both Florida and Louisiana have 1.5 million alligators. [137] Allegheny College and San Francisco State University both have Gators as their mascots, as well.[138]. The high walk is an up-on-four-limbs forward motion used for overland travel with the belly well up from the ground. The role of the alligator in shaping plant communities and maintaining wildlife in the southern Everglades. Gabrey, S. W. 2005. [73], American alligators modify wetland habitats, most dramatically in flat areas such as the Everglades, by constructing small ponds known as alligator holes. However alligators are still vulnerable to microbial infections despite the immune boost from other microbiota. 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). Young American alligators eat small fish, frogs, crayfish, and insects. B. Females hatched from eggs incubated at 30C (86F) weigh significantly more than males hatched from eggs incubated at 34C (93F). [54] In the water, American alligators swim like fish, moving their pelvic regions and tails from side to side. They cause serious damage to coastal marshes and may dig burrows in levees. As a result, an adult human can hold an alligator's jaws shut bare-handed. Together, these two subfamilies form the family Alligatoridae. [41], In some areas of their range, American alligators are an unusual example of urban wildlife; golf courses are often favoured by the species due to an abundance of water and a frequent supply of prey animals such as fish and birds. [24] A few examples of animals consumed are largemouth bass, spotted gar, freshwater pearl mussels, American green tree frogs, yellow mud turtles, cottonmouths, common moorhens, and feral wild boars. Coyotes Native to the western 2/3 of the U.S., coyotes began considerably extending their range in the early twentieth century. The acidity of the stomach has been observed to increase once digestion begins. Most animals captured by American alligators are considerably smaller than itself. The fundamental frequency has been influenced by the glottal gap size and subglottal pressure and when the phonation threshold pressure has been exceeded, there will be vocal fold vibration.[107]. Retrieved April 08, 2021, from, Thorbjarnarson, J. [122] American alligators are highly sensitive to changes in the hydrology, salinity, and productivity of their ecosystems; all are factors that are expected to change with Everglades restoration. The construction of nests along the periphery of alligator holes, as well as a buildup of soils during the excavation process, provides drier areas for other reptiles to nest and a place for plants that are intolerant of inundation to colonize. [50] Juveniles have small, needle-like teeth that become much more robust and narrow snouts that become broader as the individuals develop. [11] Male American alligators use infrasound to attract females. and early 1960's, but protective action by state and federal governments helped keep them from disappearing completely. The sprawling of American alligators and other crocodylians is not similar to that of salamanders and lizards, being similar to walking. They can grow to be more than 12 feet (3.6 meters) in length and weigh as much as 1,000 pounds (450 kilograms), with males being slightly larger than females on average. Sharks are also known to prey on American alligators, in turn, indicating that encounters between the two predators are common. [94] Mandy Stokes' alligator declared new SCI World Record, "19-Foot Alligator: The Fascinating True Story", "WATCH: Massive gator strolls through Palmetto golf course", "Famous 15-foot gator named 'Chubbs' returns to Florida golf course", "How is Chubbs the Alligator These Days? Created by the Miccosukee and Seminole tribes prior to the arrival of Europeans, this tourism tradition remains popular despite criticism from animal-rights activists.[130]. Oklahoma is home to between 100-200 individuals, but they constitute a stable population. The state has one million wild alligators and another million on alligator farms. They could survive only in captivity and are few in number. 911 Call Reveals Moments After Gator Attacks Elderly Woman. Almost all of the high-density populations of alligators live south of the Albermarle sound, although some individuals have been reported through the entire coastal region of the state. [58], Alligators are raised commercially for their meat and their skin, which when tanned is used for the manufacture of luggage, handbags, shoes, belts, and other leather items. 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.
