Today, alligator farming is a large, growing industry in Georgia, Florida, Texas, and Louisiana. Visitors may take swamp tours, in which alligators are a feature. Alligators also provide economic benefits through the ecotourism industry. In 1807, Georges Cuvier created the genus Alligator;[13] the American alligator and the Chinese alligator are the only extant species in the genus. Alligator attacks often happen when . 7 min read. Watch on. In Florida, feeding wild alligators at any time is illegal. 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. [50] These morphological changes correspond to shifts in the American alligators' diets, from smaller prey items such as fish and insects to larger prey items such as turtles, birds, and other large vertebrates. [50] Another study noted that as the American alligator increases in size, the force of its bite also increases. Nests constructed on leaves are hotter than those constructed on wet marsh, so the former tend to produce males and the latter, females. [73], American alligators modify wetland habitats, most dramatically in flat areas such as the Everglades, by constructing small ponds known as alligator holes. American Alligator Common Name: American alligators Scientific Name: Alligator mississippiensis Type: Reptiles Diet: Carnivore Group Name: Congregation Average Life Span In The Wild: 35 to 50. In 1987, the U.S. Glad You Asked", "Longest alligator in Arkansas history killed in Dumas", "Hunter bags 905-pound, problem-causing alligator; lively debate ensues", "Pathology, physiologic parameters, tissue contaminants, and tissue thiamine in morbid and healthy central Florida adult American alligators (, 10.1668/0003-1569(2000)040[0585:sfawto]2.0.co;2, "Determinate Growth and Reproductive Lifespan in the American Alligator (Alligator mississippiensis): Evidence from Long-term Recaptures", "Comparison of bite-force performance between long-term captive and wild American alligators (Alligator mississippiensis)", "Insights into the Ecology and Evolutionary Success of Crocodilians Revealed through Bite-Force and Tooth-Pressure Experimentation", "Locomotion in alligator mississippiensis: kinematic effects of speed and posture and their relevance to the sprawling-to-erect paradigm", "Kinematics of undulatory swimming in the American alligator", "Recruitment of the diaphragmaticus, ischiopubis and other respiratory muscles to control pitch and roll in the American alligator (, "Searching for the northern and southern distribution limits of two crocodilian species: Alligator mississippiensis and Crocodylus moreletii in South Texas, US, and in northern Tamaulipas, Mexico", "NAS - Nonindigenous Aquatic Species: Alligator mississippiensis", "American alligator (Alligator mississippiensis) - Species Profile", "Alligators have been sighted in Tennessee", "Alligators Expanding Range, Confirmed in", "Elusive Chattahoochee alligator caught in Cobb County", "What's the difference between a crocodile and an alligator? Adult alligators regularly cannibalize younger individuals, though estimates of the rate of cannibalism vary widely. 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. Throughout the year (in particular during the breeding season), American alligators bellow to declare territory, and locate suitable mates. [106] Their vocal folds consists of epithelium, lamina propria and muscle. Large alligators feed extensively on coypu, and provide a vital ecological service by reducing coypu numbers.[27]. [24] Hatchlings gather into pods and are guarded by their mother and keep in contact with her through their "yelping" vocalizations. For the first time since efforts began to reintroduce the species into the wild, the number of Mexican gray wolves in Arizona and New Mexico has surpassed . [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. An easy characteristic to distinguish the two is the fourth tooth. Louisiana has the largest alligator population. 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. If fed, the alligators will eventually lose their fear of humans and will learn to associate humans with food.[34]. The acidity of the stomach has been observed to increase once digestion begins. Protection under the Endangered Species Act allowed the species to recuperate in many areas where it had been depleted. The least populous of the compared places has a population of 383,899. [23] Recently a seven-foot alligator was videoed by TWRA Region 1 personnel in West Tennessee at the Wolf River WMA in Fayette County. Herpetologica, 99-107. Alligators first appeared during the Oligocene epoch about 37million years ago. 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]. [57][58] The Aquarium of the Americas in New Orleans has leucistic alligators found in a Louisiana swamp in 1987. [44], While noticeable in very mature specimens, the sexual dimorphism in size of the American alligator is relatively modest among crocodilians. [21][22] A small population is also found in Tamaulipas, in Mexico. The American alligator was abundant in the pre-drainage Everglades in south Florida. Grizzly is observing in the U.S. states of Washington, Idaho, Montana, Wyoming, and Montana. Unexpected effects of predators upon their prey: The case of the American alligator. Females hatched from eggs incubated at 30C (86F) weigh significantly more than males hatched from eggs incubated at 34C (93F). Leidyosuchus of Alberta is the earliest known fossil, from the Campanian era 83 to 72 Mya. [3], Alligators and caimans split in North America during the early Tertiary or late Cretaceous (about 53 million to about 65 million years ago). Fish and Wildlife, both Florida and Louisiana have 1.5 million alligators. may seem too good to be true, but then, some truths are quite incredible in themselves. An alligator, or just gator, is a large reptile in the Crocodilia order in the genus Alligator of the family Alligatoridae. [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. Young are born with yellow bands around their bodies and are protected by their mother for up to one year.[12]. 1998. Most American alligators eat a wide variety of animals, including invertebrates, fish, birds, turtles, snakes, amphibians, and mammals.

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]. According to the 2022 annual count, the U.S. population of Mexican wolves has increased, raising the total number of wolves in the wild to a minimum of 241 animals, a 23 percent increase. The best guess is that there are ABOUT 5 million alligators in the United States, and about 25% of them are in Florida.But they also live in Texas, Louisiana, Mississippi, Alabama, Georgia, the Carolinas and MAYBE even Tennessee. The right to left shunt of the heart in alligators means the circulatory system will recirculate blood through the body instead of back to the lungs. [118] They are preyed on by large fish, birds, raccoons, Florida panthers, and adult American alligators. Reproduction [22][23], During the 19th and 20th centuries, larger males reaching 5 to 6m (16ft 5in to 19ft 8in) were reported. [70] This adaptiveness is thought to be why American alligators are widespread further north than the American crocodile. Sharks are also known to prey on American alligators, in turn, indicating that encounters between the two predators are common. The American alligator was first classified by French zoologist Franois Marie Daudin as Crocodilus mississipiensis in 1801. [137] Allegheny College and San Francisco State University both have Gators as their mascots, as well.[138]. 1987. During summer, males still preferred open water, while females remained in the swamps to construct their nests and lay their eggs. [88], Other animals may occasionally be eaten, even large deer or feral wild boars, but these are not normally part of the diet. [50][48] The alligator's metabolism will also increase after a meal by up to four times its basal metabolic rate. [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. [24] Other prey, including snakes, lizards, and various invertebrates, are eaten occasionally by adults. F. Wayne King, John Thorbjarnarson and Carlos Yamashita. [25] In Arkansas, a man killed an American alligator that was 4.04m (13ft 3in) and 626kg (1,380lb). 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. pp. Alligators in the wild can live up to 70 years; some in captivity may live even longer. The Cuban crocodile, "Trappers catch crocodile in Lake Tarpon," Tampa Bay Times, July 12, 2013. [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. [57], American alligators, being native both to the Nearctic and Neotropical realms, are found in the wild in the Southeastern United States, from the Lowcountry in South Carolina, south to Everglades National Park in Florida, and west to the southeastern region of Texas. 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. [104], In East Texas, diets were diverse and adult American alligators took mammals, reptiles, amphibians, and invertebrates (e.g. [89] Rarely, American alligators have been observed killing and eating bobcats, but such events are not common and have little effect on bobcat populations. Usually, terrestrial hunting occurs on nights with warm temperatures. [32], Most of the muscle in an alligator's jaw evolved to bite and grip prey. This is not often seen, since if disturbed, they quickly retreat back into the water by jumping from their perch. [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. Florida has a population of 1.3 million alligators across its 67 counties, and they can be found in practically all fresh water bodies and occasionally in salt water. Oklahoma is home to between 100-200 individuals, but they constitute a stable population. Some 23 dead whales have washed ashore along the East Coast since early December, including 12 in New Jersey and New York. [24] When they construct alligator holes in the wetlands, they increase plant diversity and provide habitat for other animals during droughts. [127] Only nine fatal attacks occurred in the United States throughout the 1970s1990s, but American alligators killed 12 people between 2001 and 2007. [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. The largest of the species (both males and females) defend prime territory; smaller alligators have a higher tolerance for other alligators within a similar size class. 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. [59] Louisiana has the largest American alligator population of any U.S. state. The researchers concluded that the gators, which are at the northern end of their range in this state, could be vulnerable to hunting. [20] The majority of American alligators inhabit Florida and Louisiana, with over a million alligators in each state. In its plan, the state described the alligator population stretching just north of Albemarle Sound and as far west as Robeson County. It is believed this portion of the stomach serves a similar function as it does in the gizzard of some species of birds, to aid in digestion. Keddy, P.A. Adults range in color from black or dark gray to dark olive. 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. Such general rules include: Alligator in the Everglades National Park, Alligator in the Canberra Zoo in Australia, Juvenile alligator found in Everglades National Park. [46] Alligators have a two-part stomach, with the first smaller portion containing gastroliths. Males rarely exceed 13 feet in length and large males can weigh well over 500 pounds. [20] The majority of American alligators inhabit Florida and Louisiana, with over a million alligators in each state. By the way, Florida declared the alligator their official state reptile in 1987. Rootes, W. L., & Chabreck, R. H. (1993). 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. [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. Alligators are naturally expanding their range into Tennessee from the southern border states. [35][36] Their stomachs also often contain gizzard stones. Coyotes Native to the western 2/3 of the U.S., coyotes began considerably extending their range in the early twentieth century. They play an important role as ecosystem engineers in wetland ecosystems through the creation of alligator holes, which provide both wet and dry habitats for other organisms. Miami MetroZoo in Florida also has a breeding pair of Chinese alligators. [113] Observers of large bellowing choruses have noted they are often felt more than they are heard due to the intense infrasound emitted by males. [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. An X-ray revealed that she . View Case History American Alligator(1).pdf from FW 350 at Oregon State University, Corvallis. [135] Several organizations and products from Florida have been named after the animal. 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 . This latest sighting is one of several confirmed sightings of alligators in Southwest Tennessee. The American alligator is a stunning example of a species that has fully recovered in large part due to protections provided by the Endangered Species Act. Alligators that go long enough without a meal during brumation will begin a process called autophagy, where the animal begins to consume its fat reserves to maintain its body weight until it can acquire a sufficient meal. Captured alive by John Avery and died en route to the Smithsonian Institution after a sailor poured green paint on its back. 497 p. Chapter 4. [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. Indeed, far more Chinese alligators live in zoos around the world than can be found in the wild. [citation needed], Alligators, much like birds, have been shown to exhibit unidirectional movement of air through their lungs. American alligators have 74-80 teeth. An alligator measuring 19 ft. 2 in. The role of the alligator in shaping plant communities and maintaining wildlife in the southern Everglades. The conservation status of the American alligator is listed as Least Concern by the International Union for Conservation of Nature. [38] Another form of male display is a loud head-slap. [22], Water birds, such as herons and egrets, storks, waterfowl and large dabbling rails such as gallinules or coots, are taken when possible. The alligator is no longer endangered. Adult male American alligators measure 3.4 to 4.6m (11.2 to 15.1ft) in length, and can weigh up to 450kg (1,000lb), with unverified sizes of up to 5.84m (19.2ft) and weights of 1,000kg (2,200lb) making it the second longest member of the family Alligatoridae, after the black caiman, while being the heaviest. [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. [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. [72], American alligators primarily bask on shore, but also climb into and perch on tree limbs to bask if no shoreline is available. 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. The high walk is an up-on-four-limbs forward motion used for overland travel with the belly well up from the ground. By conserving habitat and strictly controlling hunting and trade, we have been able to increase the population to the point where sustainable harvest programs provide economic incentives to . [46] Given that female American alligators have relatively higher survival rates at an early age and a large percentage of given populations consists of immature or young breeding American alligators, relatively few large mature males of the expected mature length of 3.4m (11ft 2in) or more are typically seen. In Louisiana, alligators are most common in coastal marshes. [50] American alligators have broad snouts, especially in captive individuals. In 1967, the American alligator was listed as an endangered species (under a law that was the precursor Endangered Species Act of 1973), since it was believed to be in danger of extinction throughout all or a significant portion of its range. Louisiana has the highest alligator population, approaching 2 million (alligatorfur.com) According to U.S. The American alligator is a relatively large species of crocodilian. Since hunting and trapping preferentially take the large American alligators that are the most important in eating nutria, some changes in harvesting may be needed to capitalize on their ability to control nutria. [2] Later English spellings of the name included allagarta and alagarto. -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. 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. )", "Crocodilian Species - American Alligator (Alligator mississippiensis)". 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. 1989. Louisiana has the largest alligator population. Population by Place in the United States. [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. This listing provides federal protection for alligators but allows state-approved management and control programs. Large adult American alligators tend to be relatively robust and bulky compared to other similar-length crocodilians; for example, captive males measuring 3 to 4m (9ft 10in to 13ft 1in) were found to weigh 200 to 350kg (440 to 770lb), although captive specimens may outweigh wild specimens due to lack of hunting behavior and other stressors. 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). Juveniles also make a distress call to alert their mothers if they are being threatened. [43], There is a common belief stated throughout reptilian literature that crocodilians, including the American alligator, exhibit indeterminate growth, meaning the animal continues to grow for the duration of its life. This differs from Nile crocodiles, which lay their eggs in pits. They are opportunists and their diet is determined largely by both their size and age and the size and availability of prey. [10] The largest ever recorded, found in Louisiana, measured 5.84m (19.2ft). Critical to the alligator's ability to initiate a death roll, the tail must flex to a significant angle relative to its body. In this role as a top predator, it may determine the abundance of prey species, including turtles and coypu. Wetland Ecology: Principles and Conservation (2nd edition). [47], Dorsally, adult American alligators may be olive, brown, gray, or black. [94] In places like South Carolina, the alligator population is now estimated to be as much as 16 times higher than in the mid-1970s. [117] The female remains near the nest throughout the 65-day incubation period, protecting it from intruders. 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]. Cambridge University Press, Cambridge, UK. Oxygen exchange takes place in extensive vasculature around the parabronchi. Additionally, it weighs considerably less, with males rarely over 45kg (100lb). Alligator attacks an 85 year-old grandmother walking her dog in a retirement community in Fort Pierce, Florida. Alligator holes retain water during the dry season and provide a refuge for aquatic organisms, which survive the dry season by seeking refuge in alligator holes, so are a source of future populations. [136] The mascot stuck, and was made official in 1911, perhaps because the team captain's nickname was Gator. For the history, the United States is the only nation on earth where both alligators and . [115] The female builds a nest of vegetation, sticks, leaves, and mud in a sheltered spot in or near the water. When young, alligators eat fish, insects, snails, crustaceans, and worms. Such incidents usually involve a panther trying to cross a waterway or coming down to a swamp or river to get a drink. [27], Alligator meat is also consumed by humans.[59][60]. In the future, possible American alligator populations may be found in areas of Mexico adjacent to the Texas border. Historically, hunting had decimated their population, and the American alligator was listed as an endangered species by the Endangered Species Act of 1973. The mating season is in late spring. Legal Status. [29][30][31], Although the alligator has a heavy body and a slow metabolism, it is capable of short bursts of speed, especially in very short lunges. [16][17], Alligators are native to only the United States, Mexico, and China. The state has one million wild alligators and another million on alligator farms. Alligators can be legally taken only . This may encourage people to approach alligators and their nests, which can provoke the animals into attacking. No significant difference is noted between the bite forces of male and female American alligators of equal size. [114], American alligators typically live to the age of 50, and possibly over 70 years old. [54] In the water, American alligators swim like fish, moving their pelvic regions and tails from side to side. [24] As they grow and develop, the morphology of their teeth and jaws change significantly. [53], When on land, an American alligator moves either by sprawling or walking, the latter involving the reptile lifting its belly off the ground. Impacts of the coypu removal program on the diet of American alligators (. B. Females generally grow to less than 9 feet and weigh up to 200 pounds. 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. [3], They inhabit swamps, streams, rivers, ponds, and lakes. The Florida Naturalist, 41, 27, 6974. The discovery of this unexpected part of the American alligator diet further reveals that they may be responsible for spreading seeds from the fruit they consume across their habitat. [22], In 2013, American alligators and other crocodilians were reported to also eat fruit. The dermal bones are highly vascularised and aid in calcium balance, both to neutralize acids while the animal cannot breathe underwater[55] and to provide calcium for eggshell formation.[56]. Alligators have muscular, flat tails that propel them while swimming. Members of this superfamily first arose in the late Cretaceous, about 10065 million years ago (Mya). This page was last edited on 1 March 2023, at 04:33. [12], No average lifespan for an alligator has been measured. American alligators are apex predators and consume fish, amphibians, reptiles, birds, and mammals. Alligator holes are an oasis during the Everglades dry season, so are consequently important foraging sites for other organisms. This alligator and the American alligator are now considered to be sister taxa, meaning that the A. mississippiensis lineage has existed in North America for over 8 million years. The sprawl is a forward movement with the belly making contact with the ground and is used to transition to "high walk" or to slither over wet substrate into water. 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. It has a large, long head with visible upper teeth along the edge of the jaws. By balancing sticks and branches on their heads, American alligators are able to lure birds looking for suitable nesting material to kill and consume. [21] [22] A small population is also found in Tamaulipas, in Mexico. Gabrey, S. W. 2005. This strategy, which is shared by the mugger crocodile, is particularly effective during the nesting season, in which birds are more likely to gather appropriate nesting materials. In order to understand and properly manage Texas's alligator population, TPWD Wildlife Division conducts extensive studies in the state on the number, character and harvest of alligators every year. [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. The wild population of Mexican wolves in the United States continued to grow in 2022. [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.
