Alabama is in the outlying part of the American Alligator's range, so the population boom was a bit slower there. [13] One of the oldest recorded alligator lives was that of Saturn, an American alligator who was hatched in 1936 in Mississippi and spent nearly a decade in Germany before spending the majority of its life at the Moscow Zoo, where it died at the age of 83 or 84 on 22 May 2020. [5][6][7][8][9] The American alligator inhabits subtropical and tropical freshwater wetlands, such as marshes and cypress swamps, from southern Texas to North Carolina. [118] They are preyed on by large fish, birds, raccoons, Florida panthers, and adult American alligators. [29], American alligators do not normally reach such extreme sizes. The alligator is no longer endangered. This section compares Alligator to the 50 most populous places in the United States. [70] In fact, the American alligator is found farther from the equator and is more equipped to handle cooler conditions than any other crocodilian. [24] The largest reported individual size was a male killed in 1890 on Marsh Island, Louisiana, and reportedly measured at 5.84m (19ft 2in) in length, but no voucher specimen was available, since the American alligator was left on a muddy bank after having been measured due to having been too massive to relocate. [24] When they construct alligator holes in the wetlands, they increase plant diversity and provide habitat for other animals during droughts. American alligators bellow in B flat (specifically "B1", defined as an audio frequency of 58.27Hz), and bellowing choruses can be induced by tuba players, sonic booms, and large aircraft. [60] Alligators have been naturally expanding their range into Tennessee,[61] and have established a small population in the southwestern part of that state via inland waterways, according to the state's wildlife agency. [84] Stomach contents show, among native mammals, muskrats and raccoons are some of the most commonly eaten species. [23] These states produce a combined annual total of some 45,000 alligator hides. [16], The alligator's full mitochondrial genome was sequenced in the 1990s, and it suggests the animal evolved at a rate similar to mammals and greater than birds and most cold-blooded vertebrates. Gatorland's denizens roar in ecstasy", "Spatial and temporal variation in nest temperatures forecasts sex ratio skews in a crocodilian with environmental sex determination", Python explodes after swallowing 6-foot alligator in Florida Everglades, USGS Maps Show Potential Non-Native Python Habitat Along Three U.S. As the alveoli represent dead-ends to flow, the inspired air must move back out the same way it came in. Fish and Wildlife Service pronounced the American alligator fully recovered. The polar bear lives only in Alaska. The animal's dark skin is armored with small, bony scales called scutes. They could only survive in captivity, as they are very vulnerable to the sun and predators.[49]. [100] Additionally, American alligators engage in what seems to be cooperative hunting. [39] In 2010, on spring nights alligators were found to gather in large numbers for group courtship, the so-called "alligator dances". Louisiana and Florida. [42][43] In the past, immediately following the outlawing of alligator hunting, populations rebounded quickly due to the suppressed number of adults preying upon juveniles, increasing survival among the young alligators. The Chinese alligator likely descended from a lineage that crossed the Bering land bridge during the Neogene. American alligators have 74-80 teeth. If fed, the alligators will eventually lose their fear of humans and will learn to associate humans with food.[34]. The Gatornationals is a NHRA drag race held at the Gainesville Raceway in Gainesville since 1970. [51] Alligators also have highly folded mucosa in the lining of the intestines to further aid in the absorption of nutrients. As they mature, progressively larger prey is taken, including larger fish such as gar, turtles, and various mammals, particularly coypu and muskrat,[24] as well as birds, deer, and other reptiles. The baby alligator's egg tooth helps it get out of its egg during hatching time. Cambridge University Press, Cambridge, UK. [135] Several organizations and products from Florida have been named after the animal.

[127] Only nine fatal attacks occurred in the United States throughout the 1970s1990s, but American alligators killed 12 people between 2001 and 2007. This doesn't mean that residents should expect to see an alligator hanging out on every corner, but they shouldn't necessarily be shocked to spot an Alligator now and again either. It is estimated that five million American alligators are spread out across the southeastern United States and around 1.25 million alligators live in the state of Florida. [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. [105], An American alligator is able to abduct and adduct the vocal folds of its larynx, but not to elongate or shorten them; yet in spite of this, it can modulate fundamental frequency very well. Male alligators grow faster and larger than females. [11] The Chinese alligator is smaller, rarely exceeding 2.1m (7ft) in length. [44] Most other amniotes are believed to exhibit bidirectional, or tidal breathing. Georgia The state of Georgia is no stranger to Alligators, and that is particularly true for the southeast quadrant of the state. While they prefer fresh water, American alligators may sometimes wander into brackish water,[66] but are less tolerant of salt water than American crocodiles, as the salt glands on their tongues do not function. 7 min read. [49] There is evidence to suggest that there is increased blood flow diverted to the stomach during digestion to facilitate an increase in CO2 concentration which aids in increasing gastric acid secretions during digestion. It has more alligators than any other state. [19] Weight varies considerably depending on length, age, health, season, and available food sources. An X-ray revealed that she . In NC, males can reach 13 feet and weigh up to 500 pounds or more. American alligators are often less aggressive towards humans than larger crocodile species, a few of which (mainly the Nile and saltwater crocodiles) may prey on humans with some regularity. [22], Water birds, such as herons and egrets, storks, waterfowl and large dabbling rails such as gallinules or coots, are taken when possible. Substantial American alligator populations in the Everglades might be a contributing factor, as a competitor, in keeping the python populations low, preventing the spread of the species north. Alligator feeding habits: New data and a review. [87], If an American alligator's primary food resource is not available, it will sometimes feed on carrion and non-prey items such as rocks and artificial objects, like bottle caps. 1998. [22], In 2013, American alligators and other crocodilians were reported to also eat fruit. This marks the seventh consecutive year of growth in the wild population. Such behavior has been witnessed, as well as documented from stomach contents, with the American alligators eating such fruit as wild grapes, elderberries, and citrus fruits directly from the trees. These alligators are practically impossible to find in the wild. Alligators are naturally expanding their range into Tennessee from the southern border states. 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. Cooperative Feeding, A Misinterpreted and Under-Reported Behavior of Crocodilians. Once an American alligator reaches full size and power in adulthood, any animal living in the water or coming to the water to drink is potential prey. The Florida Naturalist, 41, 27, 6974. [85] In Louisiana, where introduced coypu are common, they are perhaps the most regular prey for adult American alligators, although only larger adults commonly eat this species. TPWD issues the tags, required by state and federal law, based on the alligator population on the privately owned tract. Wolfe, J. L., D. K. Bradshaw, and R. H. Chabreck. Juveniles also make a distress call to alert their mothers if they are being threatened. [48] The re-circulation of blood leads to higher CO2 concentration as well as lower oxygen affinity. Unexpected effects of predators upon their prey: The case of the American alligator. [10] It is distinguished from the sympatric American crocodile by its broader snout, with overlapping jaws and darker coloration, and is less tolerant of saltwater but more tolerant of cooler climates than the American crocodile, which is found only in tropical and warm subtropical climates. Alligators generally mature at a length of 1.8m (6ft). [4][5] The Chinese alligator split from the American alligator about 33 million years ago[4] and probably descended from a lineage that crossed the Bering land bridge during the Neogene. This is due to the increase in CO2 concentration of the blood, resulting from the right to left shunting of the alligators heart. This latest sighting is one of several confirmed sightings of alligators in Southwest Tennessee. Louisiana has the highest population of alligators in the United States, and it is least surprising that the largest alligator ever recorded was also found in this state. Large male alligators are solitary territorial animals. It is enclosed in a pocket in the upper jaw. Southern Florida is the only place where both alligators and crocodiles live side by side. Subsequent conservation efforts have allowed their numbers to increase and the species was removed from endangered status in 1987. Today, alligator farming is a large, growing industry in Georgia, Florida, Texas, and Louisiana. [3], Alligators and caimans split in North America during the early Tertiary or late Cretaceous (about 53 million to about 65 million years ago). Juveniles can perform a high-pitched hatchling call (a "yelping" trait common to many crocodilian species' hatchling young)[109] to alert their mothers when they are ready to emerge from the nest. It is one of the two extant species in the genus Alligator, and is larger than the only other living alligator species, the Chinese alligator. It is one of the two extant species in the genus Alligator, and is larger than the only other living alligator species, the Chinese alligator . [44], While noticeable in very mature specimens, the sexual dimorphism in size of the American alligator is relatively modest among crocodilians. [116] The nests built on levees are warmer, thus produce males, while the cooler nests of wet marsh produce females. [47], Dorsally, adult American alligators may be olive, brown, gray, or black. Unlike the other extinct alligator species of the same genus, the fossil skull was virtually indistinguishable from that of the modern American alligator. [26] The largest American alligator ever killed in Florida was 5.31m (17ft 5in), as reported by the Everglades National Park, although this record is unverified. [6] The full genome, published in 2014, suggests that the alligator evolved much more slowly than mammals and birds. Females are produced at temperatures less than 31.5oC; mixed sex ratios occur at 32oC, and males only are produced when temperatures are between 32.5 and 33oC. [1], The name "alligator" is probably an anglicized form of el lagarto, the Spanish term for "the lizard", which early Spanish explorers and settlers in Florida called the alligator.

The Amphibians and Reptiles of Louisiana. [92] In the 2000s, when invasive Burmese pythons first occupied the Everglades, American alligators have been recorded preying on sizable snakes, possibly controlling populations and preventing the invasive species from spreading northwards. They are grouped in the family Alligatoridae with the caimans. Whenever an American alligator's mouth is closed, the fourth tooth is no longer visible. An easy characteristic to distinguish the two is the fourth tooth. [1] The alligator's full mitochondrial genome was sequenced in the 1990s. In Florida, feeding wild alligators at any time is illegal. 10. Herpetologica, 99-107. [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. [137] Allegheny College and San Francisco State University both have Gators as their mascots, as well.[138]. [28] Alligators have also been observed to rise up and balance on their hind legs and semi-step forward as part of a forward or upward lunge. 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;[51][52] 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. Visitors may take swamp tours, in which alligators are a feature. The bellows of male American alligators are accompanied by powerful blasts of infrasound. This behavior has qualified the American alligator to be considered a keystone species. On average, it is the largest species in the family Alligatoridae, with only the black caiman being possibly longer. Florida . Captured alive by John Avery and died en route to the Smithsonian Institution after a sailor poured green paint on its back. The modern American alligator is well represented in the fossil record of the Pleistocene. Louisiana What States have alligators? [136] The mascot stuck, and was made official in 1911, perhaps because the team captain's nickname was Gator. This listing has been adopted by the State of Florida. Nests constructed on leaves are hotter than those constructed on wet marsh, so the former tend to produce males and the latter, females. The conservation status of the American alligator is listed as Least Concern by the International Union for Conservation of Nature. Fossils identical to the existing American alligator are found throughout the Pleistocene, from 2.5 million to 11.7 thousand years ago. Louisiana has the highest alligator population, currently approaching 2 million. Adult American alligators also spend considerable time hunting on land, up to 160 feet (50m) from water, ambushing terrestrial animals on trailsides and road shoulders. Alligator hides bring good prices and hides in the 6- to 7-ft range have sold for $300 each. [22] Meanwhile, their undersides are cream-colored. As human populations increase, and as they build houses in low-lying areas, or fish or hunt near water, incidents are inevitable where humans live near American alligators and their habitats. Oxygen exchange takes place in extensive vasculature around the parabronchi. Louisiana has the highest alligator population, approaching 2 million (alligatorfur.com) According to U.S. pp. 497 p. Chapter 4. [110] Males are known to use infrasound during mating bellows. The role of the alligator in shaping plant communities and maintaining wildlife in the southern Everglades. Therefore, the two forms of land locomotion can be termed the "low walk" and the "high walk". The American alligator is the official state reptile of Florida,[133] Louisiana,[134] and Mississippi. The young are tiny replicas of adults, with a series of yellow bands around their bodies that serve as camouflage. The wild population of Mexican wolves in the United States continued to grow in 2022. [citation needed], Alligators, much like birds, have been shown to exhibit unidirectional movement of air through their lungs. However, they are on average one of the most darkly colored modern crocodilians (although other alligatorid family members are also fairly dark), and can be reliably be distinguished by color via their more blackish dorsal scales against crocodiles. Its front feet have 5 toes, while rear feet have 4 toes that are webbed. [104], In East Texas, diets were diverse and adult American alligators took mammals, reptiles, amphibians, and invertebrates (e.g. Alligators' main prey are smaller animals they can kill and eat with a single bite. )", "Crocodilian Species - American Alligator (Alligator mississippiensis)". The folds result in greater surface area for the nutrients to be absorbed through. Protection under the Endangered Species Act allowed the species to recuperate in many areas where it had been depleted. The nearly five-foot alligator was found "extremely emaciated" in a lake in New York City's Prospect Park on February 19, the Wildlife Conservation Society (WCS) said. Alligator Data and Reports Alligator management programs implemented by FWC emphasize the conservation of alligator populations for their ecological, aesthetic, and economic values while providing for public use and safety. The type of food eaten by alligators depends upon their age and size. 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. Alligators in the wild can live up to 70 years; some in captivity may live even longer. 9 p. Available at: McLaughlin, Eliott C.; Almasy, Steve and Shoichet, Catherine E.

In Lake Griffin, fish made up 54% of the diet by weight, with catfish being most commonly consumed, while in Lake Apopka, fish made up 90% of the food and mostly shad were taken; in Lake Woodruff, the diet was 84% fish and largely consists of bass and sunfish. During summer, males still preferred open water, while females remained in the swamps to construct their nests and lay their eggs. "Gators" has been the nickname of the University of Florida's sports teams since 1911. Some 23 dead whales have washed ashore along the East Coast since early December, including 12 in New Jersey and New York. [50] American alligators have broad snouts, especially in captive individuals. In contrast, air in alligator lungs makes a circuit, moving in only one direction through the parabronchi. [24] As they grow and develop, the morphology of their teeth and jaws change significantly. The natural sex ratio at hatching is five females to one male. [94] Alligator in captivity The states that have alligators are Florida, Mississippi, Texas, Louisiana, Alabama, North and South Carolina, and Georgia. 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. Additionally, several extinct species of alligator are known from fossil remains. On spring nights, American alligators gather in large numbers for group courtship, in the aforementioned "water dances". [25] In Arkansas, a man killed an American alligator that was 4.04m (13ft 3in) and 626kg (1,380lb). Leidyosuchus of Alberta is the earliest known fossil, from the Campanian era 83 to 72 Mya. While there are rules of thumb for distinguishing alligators from crocodiles, all of them admit exceptions. [82][83] As they grow, American alligators gradually expand to larger prey. Coasts, "The American Alligator: An Indicator Species for Everglades Restoration", "Nesting Island Creation for Wading Birds", Crocodile and Alligator Differences Animal Facts for Kids, Disney alligator attack: Resort to add warning signs, source says, 10.1580/1080-6032(2005)16[119:AAOHIT]2.0.CO;2, "A String of Deaths by Gators in Florida", "Alligator wrestling cruelty or tradition? 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. 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. 2010. Miami MetroZoo in Florida also has a breeding pair of Chinese alligators. [20] The majority of American alligators inhabit Florida and Louisiana, with over a million alligators in each state. [8][9] In Newnans Lake, Florida, adult males averaged 73.2kg (161lb) in weight and 2.47m (8ft 1in) in length, while adult females averaged 55.1kg (121lb) and measured 2.22m (7ft 3in). The victim's neighbor can be heard on a 911 call as Gloria Serge was dragged underwater. This page was last edited on 1 March 2023, at 04:33. Alligators have muscular, flat tails that propel them while swimming. -23.28% (-27) Rank in State 354th Rank in Country 26937th The current population of Alligator, Mississippi is 89 based on our projections of the latest US Census estimates.The last official US Census in 2020 recorded the population at 116. [65] Females and juveniles are also found in Carolina Bays and other seasonal wetlands. [96][97][98], Occasionally, domestic animals, including dogs, cats, and calves, are taken as available, but are secondary to wild and feral prey. 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]. Mistaken identity leading to an attack is always possible, especially in or near cloudy waters. [99] Sex of alligators is determined by nest temperatures during the middle third of embryo development. (1993). They cause serious damage to coastal marshes and may dig burrows in levees. Fossil alligatoroids have been found throughout Eurasia, because bridges across both the North Atlantic and the Bering Strait connected North America to Eurasia about 66 to 23 Mya. [20][21], Large male American alligators reach an expected maximum size up to 4.6m (15ft 1in) in length and weighing up to 453kg (999lb), while females reach a maximum of 3m (9ft 10in). Since 1948, 257 documented attacks on humans in Florida (about five incidents per year) have been reported, of which an estimated 23 resulted in death. Similar to many other reptiles that range expansively into temperate zones, American alligators from the northern end of their range, such as southern Arkansas, Alabama, and northern North Carolina, tend to reach smaller sizes. [118] Young alligators grow 38in (7.620.3cm) a year and reach adulthood at 6ft (1.8m). Historically, hunting had decimated their population, and the American alligator was listed as an endangered species by the Endangered Species Act of 1973. This type of protection allowed the alligator population to increase. The 11 feet-long gator was later captured and killed. American alligators prevent predatory mammals from reaching island-based rookeries and in return eat spilled food and birds that fall from their nests. Unusually in these regions, reptiles and amphibians were the most important nonpiscivore prey, mostly turtles and water snakes. When the jaws are closed, the edges of the upper jaws cover the lower teeth, which fit into the jaws' hollows. Gabrey, S. W. 2005. States began monitoring their American alligator populations to ensure that they would continue to grow. Retrieved April 08, 2021, from, Thorbjarnarson, J. 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. [95] American alligator predation on American black bears has also been recorded. Alligators. Virginia Living Museum. The alligator now has a status of "threatened due to ", "Alternative Opportunities for Small Farms:Alligator Production Review", "Gator Maters: Florida farmers find lucrative business mating alligators", Why the Gulf Coast needs more big alligators, https://en.wikipedia.org/w/index.php?title=American_alligator&oldid=1142219793, Approximate range of American alligator in the United States. Alligator hunters, pelt traders, and runaway consumption of Gulf coast marshes: A trophic cascade perspective on coastal wetland losses. In 1987, the USFWS removed the animal from the endangered species list, as it was considered to be fully recovered. The superfamily Alligatoroidea includes all crocodilians (fossil and extant) that are more closely related to the American alligator than to either the Nile crocodile (Crocodylus niloticus) or the gharial (Gavialis gangeticus).[14]. [11] Male American alligators use infrasound to attract females. The sprawling of American alligators and other crocodylians is not similar to that of salamanders and lizards, being similar to walking. [20] A specimen that was 4.8m (15ft 9in) long and weighed 458.8kg (1,011.5lb) is the largest American alligator killed in Alabama and has been declared the SCI world record in 2014. Only one of the American alligators was collected from the Colorado River, Mesa County, Colorado; the other was never recaptured, but there is no evidence of an established population (Livo et al., 1998). Anonymous 2 y Related What is the state with the most alligators? American alligators occasionally prey on large mammals, such as deer, but usually do so when fish and smaller prey levels go down. [90][91] Although American alligators have been listed as predators of the Nilgai and the West Indian manatees, very little evidence exists of such predation. Hence, Louisiana has had a bounty to try to reduce nutria numbers. [14][15] Another one of the oldest lives on record is that of Muja, an American alligator who was brought as an adult specimen to the Belgrade Zoo in Serbia from Germany in 1937. Their body alone ranges from 6 - 14 feet long. The high walk is an up-on-four-limbs forward motion used for overland travel with the belly well up from the ground. Sharks are also known to prey on American alligators, in turn, indicating that encounters between the two predators are common. By 1960, however, alligators had been completely eliminated from much of their former range. [128] In May 2006, American alligators killed three Floridians in less than a week. 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. Black caiman, Charles, S.; Ross, A. and Garnett, Stephen (1989), Erickson, G. M., Lappin, A. K., & Vliet, K. A. Alligators and caimans split in North America during the late Cretaceous, and the caimans reached South America by the Paleogene, before the closure of the Isthmus of Panama during the Neogene period, from about 23 to 2.58 Mya. Most of the state gets much too cold for gators to survive the winter, but there are some small regions that allow for a small population. Sounds ranged from 50 to 1200Hz. Large alligators feed extensively on coypu, and provide a vital ecological service by reducing coypu numbers.[27]. [21][22] A small population is also found in Tamaulipas, in Mexico.
