[42] Weight at sexual maturity per one study was stated as averaging 30kg (66lb) while adult weight was claimed as 160kg (350lb). [21] [22] A small population is also found in Tamaulipas, in Mexico. 1987. Gabrey, S. W. 2005. [70] The temperature at which American alligator eggs develop determines their sex (see temperature-dependent sex determination). [124], American alligators are capable of killing humans, but fatal attacks are fairly rare. Louisiana has the highest alligator population, approaching 2 million (alligatorfur.com) According to U.S. Large alligators feed extensively on coypu, and provide a vital ecological service by reducing coypu numbers.[27]. [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. These American alligators are extremely rare and almost impossible to find in the wild. [70] In fact, the American alligator is found farther from the equator and is more equipped to handle cooler conditions than any other crocodilian. No significant difference is noted between the bite forces of male and female American alligators of equal size. [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. [37][27] As humans encroach into their habitat, attacks are few but not unknown. [74] In the limestone depressions of cypress swamps, alligator holes tend to be large and deep, while those in marl prairies and rocky glades are usually small and shallow, and those in peat depressions of ridge and slough wetlands are more variable. The same google search "How many alligators live in Florida" gave me this result With an estimated 1.3 million alligators in Florida, the state's Fish and Wildlife Conservation Commission is warning [103] In southern Louisiana, crustaceans (largely crawfish and crabs) were found to be present in the southeastern American alligators, but largely absent in southwestern American alligators, which consumed a relatively high proportion of reptiles, although fish were the most recorded prey for adults, and adult males consumed a large portion of mammals. And though census numbers are hard to pin down, the plan. The two states that have the most gators are Florida and Louisiana. 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. "Gators" has been the nickname of the University of Florida's sports teams since 1911. 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. [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 Cuban crocodile, "Trappers catch crocodile in Lake Tarpon," Tampa Bay Times, July 12, 2013. It has a large, long head with visible upper teeth along the edge of the jaws. [127] Only nine fatal attacks occurred in the United States throughout the 1970s1990s, but American alligators killed 12 people between 2001 and 2007. The bellows of male American alligators are accompanied by powerful blasts of infrasound. The alligator now has a status of "threatened due to [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. [80][81], American alligators are considered an apex predator throughout their range. In 1908, a printer made a spur-of-the-moment decision to print an alligator emblem on a shipment of the school's football pennants. [63], Historically, hunting and habitat loss have severely affected American alligator populations throughout their range, and whether the species would survive was in doubt. Recently a seven-foot alligator was videoed by TWRA Region 1 personnel in West Tennessee at the Wolf River WMA in Fayette County. Indeed, far more Chinese alligators live in zoos around the world than can be found in the wild. 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. 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. This is due to the increase in CO2 concentration of the blood, resulting from the right to left shunting of the alligators heart. The alligator is no longer endangered. [19] Weight varies considerably depending on length, age, health, season, and available food sources. Baton Rouge: Louisiana State University Press. While there are rules of thumb for distinguishing alligators from crocodiles, all of them admit exceptions. [53], When on land, an American alligator moves either by sprawling or walking, the latter involving the reptile lifting its belly off the ground. Throughout the year (in particular during the breeding season), American alligators bellow to declare territory, and locate suitable mates. [25] In Arkansas, a man killed an American alligator that was 4.04m (13ft 3in) and 626kg (1,380lb). Captured alive by John Avery and died en route to the Smithsonian Institution after a sailor poured green paint on its back. 911 Call Reveals Moments After Gator Attacks Elderly Woman. 2010. 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. Females generally grow to less than 9 feet and weigh up to 200 pounds. ", "Insights into the ecology and evolutionary success of crocodilians revealed through bite-force and tooth-pressure experimentation", "American Crocodile: Species Description", https://en.wikipedia.org/w/index.php?title=Alligator&oldid=1141899701, This page was last edited on 27 February 2023, at 12:41. 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. 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. Black caiman, Charles, S.; Ross, A. and Garnett, Stephen (1989), Erickson, G. M., Lappin, A. K., & Vliet, K. A. 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. Additionally, it weighs considerably less, with males rarely over 45kg (100lb). The species is the official state reptile of three states: Florida, Louisiana, and Mississippi. [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. Oklahoma (100-200) There is a tiny population of alligators that live in certain southern regions of the state. [108] The American alligator can perform specific vocalizations to declare territory, signal distress, threaten competitors, and locate suitable mates. [73], American alligators modify wetland habitats, most dramatically in flat areas such as the Everglades, by constructing small ponds known as alligator holes. [6] The full genome, published in 2014, suggests that the alligator evolved much more slowly than mammals and birds. The gastroliths work to grind up the meal as alligators will take large bites or swallow smaller prey whole. The Chinese alligator likely descended from a lineage that crossed the Bering land bridge during the Neogene. [86][85] It has also been reported that large American alligators prey on medium-sized American alligators, which had preyed on hatchlings and smaller juveniles. The American alligator is capable of biting through a turtle's shell or a moderately sized mammal bone. The alligator has recovered from extremely low population levels in the mid-1900s and is now recreationally and commercially hunted in many southeastern states. This listing has been adopted by the State of Florida. An X-ray revealed that she . [23][125] Alligator bites are serious injuries, due to the reptile's sheer bite force and risk of infection. [32], Most of the muscle in an alligator's jaw evolved to bite and grip prey. [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. In April and May, alligators form so-called "bellowing choruses". [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. Females are smaller, measuring 2.6 to 3m (8.5 to 9.8ft) in length. [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. As a result, an adult human can hold an alligator's jaws shut bare-handed. [129] At least 28 fatal attacks by American alligators have occurred in the United States since 1970. [22] Meanwhile, their undersides are cream-colored. They cause serious damage to coastal marshes and may dig burrows in levees. 1998. In Florida, feeding wild alligators at any time is illegal. [94] On spring nights, American alligators gather in large numbers for group courtship, in the aforementioned "water dances". [22], Water birds, such as herons and egrets, storks, waterfowl and large dabbling rails such as gallinules or coots, are taken when possible. [112] Large bellowing "choruses" of American alligators during the breeding season are commonly initiated by females and perpetuated by males. 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 . This may encourage people to approach alligators and their nests, which can provoke the animals into attacking. Infrasonic waves from a bellowing male can cause the surface of the water directly over and to either side of his back to literally "sprinkle",[111] in what is commonly called the "water dance". [58] They are found in parts of North Carolina, South Carolina, Georgia, Florida, Louisiana, Alabama, Mississippi, Arkansas, Oklahoma and Texas. [3], They inhabit swamps, streams, rivers, ponds, and lakes. Protection under the Endangered Species Act allowed the species to recuperate in many areas where it had been depleted. [68][69], American alligators are less vulnerable to cold than American crocodiles. Large groups of animals bellow together for a few minutes a few times a day, usually one to three hours after sunrise. 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. 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? As the frequency increases, there's high tension and large strains. . Wading birds appear to be attracted to areas with American alligators and have been known to nest at heavily trafficked tourist attractions with large numbers of American alligators, such as the St. Augustine Alligator Farm in St. Augustine, Florida. Alligators can be legally taken only . 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. [59] Louisiana has the largest American alligator population of any U.S. state. Population by Place in the United States. In this role as a top predator, it may determine the abundance of prey species, including turtles and coypu. The breeding season begins in the spring. The animal's dark skin is armored with small, bony scales called scutes. American alligators have 74-80 teeth. Most American alligators eat a wide variety of animals, including invertebrates, fish, birds, turtles, snakes, amphibians, and mammals. They could only survive in captivity, as they are very vulnerable to the sun and predators.[49]. Coyotes Native to the western 2/3 of the U.S., coyotes began considerably extending their range in the early twentieth century.

[64], Both the United States Fish and Wildlife Service (USFWS) and state wildlife agencies in the South contributed to the American alligator's recovery. [101][102], The diet of adult American alligators from central Florida lakes is dominated by fish, but the species is highly opportunistically based upon local availability. These alligators are practically impossible to find in the wild. According to the Smithsonian's National Zoo and Conservation Biology Institute, "the American alligator is found in the United States from North Carolina to the Rio Grande in Texas. Keddy PA, Gough L, Nyman JA, McFalls T, Carter J, Siegnist J (2009). An average adult American alligator's weight and length is 360kg (790lb) and 4m (13ft), but they sometimes grow to 4.4m (14ft) long and weigh over 450kg (990lb). [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. Fossils identical to the existing American alligator are found throughout the Pleistocene, from 2.5 million to 11.7 thousand years ago. When the young begin to hatch their "yelping" calls can sometimes even be heard just before hatching commences the mother quickly digs them out and carries them to the water in her mouth,[24] as some other crocodilian species are known to do. Virginia Living Museum. American alligator predation on Florida panthers is rare, but has been documented. 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). Oklahoma is home to between 100-200 individuals, but they constitute a stable population. (1993). Females rarely exceed 9 feet in length and large females can weigh more than 200 pounds. [27], Alligator meat is also consumed by humans.[59][60]. This marks the seventh consecutive year of growth in the wild population. [128] In May 2006, American alligators killed three Floridians in less than a week. Alligators first appeared during the Oligocene epoch about 37million years ago. This information helps TPWD determine trends in the population, assess alligator habitat and establish wise hunting limits for the species. The American alligator is a relatively large species of crocodilian. Like the spectacled caiman, this species has a bony nasal ridge, though it is less prominent. [95] American alligator predation on American black bears has also been recorded. The 11 feet-long gator was later captured and killed. 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]. 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. Wolfe, J. L., D. K. Bradshaw, and R. H. Chabreck. The American alligator was abundant in the pre-drainage Everglades in south Florida. [16][17], Alligators are native to only the United States, Mexico, and China. It is common to use several wraps of duct tape to prevent an adult alligator from opening its jaws when being handled or transported. [24] Hatchlings gather into pods and are guarded by their mother and keep in contact with her through their "yelping" vocalizations. [50] American alligators have broad snouts, especially in captive individuals. Benefits include better total health and stronger immune system. Male alligators grow faster and larger than females. View Case History American Alligator(1).pdf from FW 350 at Oregon State University, Corvallis. The air first enters the outer branch, moves through the parabronchi, and exits the lung through the inner branch. [47] Once an alligator's meal has been processed it will move on to the second portion of the stomach which is highly acidic. 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. [57][58] The Aquarium of the Americas in New Orleans has leucistic alligators found in a Louisiana swamp in 1987. She will provide protection to the young for about a year if they remain in the area. [50][48] The alligator's metabolism will also increase after a meal by up to four times its basal metabolic rate. [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. [26] Farther west, in Louisiana, heavy grazing by coypu and muskrat are causing severe damage to coastal wetlands. (2016, April 30). [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. As the alveoli represent dead-ends to flow, the inspired air must move back out the same way it came in. [123] They may provide a protection service for water birds nesting on islands in freshwater wetlands. Historically, hunting had decimated their population, and the American alligator was listed as an endangered species by the Endangered Species Act of 1973. Through LDWF's extensive research and wise management that includes sustainable wild harvest and alligator farming, Louisiana's wild alligator population has increased from less than 100,000 to more than 2 million in the past 50 years. The sprawling of American alligators and other crocodylians is not similar to that of salamanders and lizards, being similar to walking. Unlike an American crocodile, which would immediately succumb to the cold and drown in water at 45F (7C) or less, an American alligator can survive in such temperatures for some time without displaying any signs of discomfort. [1] The alligator's full mitochondrial genome was sequenced in the 1990s. Journal of Zoology, 260(3), 317-327. Young are born with yellow bands around their bodies and are protected by their mother for up to one year.[12]. [66], Nutria were introduced into coastal marshes from South America in the mid-20th century, and their population has since exploded into the millions. In 1807, Georges Cuvier created the genus Alligator;[13] the American alligator and the Chinese alligator are the only extant species in the genus. Alabama is in the outlying part of the American Alligator's range, so the population boom was a bit slower there. The American alligator was first classified by French zoologist Franois Marie Daudin as Crocodilus mississipiensis in 1801. This behavior has qualified the American alligator to be considered a keystone species. Gators remain fully protected in North Carolina, unlike those in eight states from South Carolina to Arkansas and Texas, which allow hunting. Alligators. Critical to the alligator's ability to initiate a death roll, the tail must flex to a significant angle relative to its body. However, these claims are largely based on assumptions and observations of juvenile and young adult crocodilians, and recent studies are beginning to contradict this claim. The least populous of the compared places has a population of 383,899. 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. [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. [41] In Lake Griffin State Park, Florida, adults weighed on average 57.9kg (128lb). The acidity of the stomach has been observed to increase once digestion begins. [44], While noticeable in very mature specimens, the sexual dimorphism in size of the American alligator is relatively modest among crocodilians. By balancing sticks and branches on their heads, American alligators are able to lure birds looking for suitable nesting material to kill and consume. [40], In summer, the female builds a nest of vegetation where the decomposition of the vegetation provides the heat needed to incubate the eggs. The conservation status of the American alligator is listed as Least Concern by the International Union for Conservation of Nature. 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? Alligators move on land by two forms of locomotion referred to as "sprawl" and "high walk". Fish and Wildlife, both Florida and Louisiana have 1.5 million alligators. Today, alligator farming is a large, growing industry in Georgia, Florida, Texas, and Louisiana. This process makes digestion and nutrient absorption easier once the food reaches the second portion of the stomach. Keddy, P.A. 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. This latest sighting is one of several confirmed sightings of alligators in Southwest Tennessee. Large male alligators are solitary territorial animals. [24] As they grow and develop, the morphology of their teeth and jaws change significantly. Whenever an American alligator's mouth is closed, the fourth tooth is no longer visible. [48] The re-circulation of blood leads to higher CO2 concentration as well as lower oxygen affinity. [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. 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]. [38] Another form of male display is a loud head-slap. 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. [72], American alligators primarily bask on shore, but also climb into and perch on tree limbs to bask if no shoreline is available. 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. 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. The ontogeny of bite-force performance in American alligator (Alligator mississippiensis). 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. Adult alligators regularly cannibalize younger individuals, though estimates of the rate of cannibalism vary widely. [62], American alligators are currently listed as least concern by the IUCN Red List, even though from the 1800s to the mid-1900s, they were being hunted and poached by humans unsustainably. [84] Stomach contents show, among native mammals, muskrats and raccoons are some of the most commonly eaten species. However, in the past few years, the population has also grown in these places. [23] If the size of this animal was correct, it would have weighed about 1,000kg (2,200lb). Biologists recently estimated that the state has between 32,000 and 38,000 alligators, far fewer than either Florida or Louisiana. Rootes, W. L., & Chabreck, R. H. (1993). For the history, the United States is the only nation on earth where both alligators and . There are 29,322 places in the United States. [96][97][98], Occasionally, domestic animals, including dogs, cats, and calves, are taken as available, but are secondary to wild and feral prey. The modern American alligator is well represented in the fossil record of the Pleistocene. [24] When they construct alligator holes in the wetlands, they increase plant diversity and provide habitat for other animals during droughts. [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.
