[23] If the size of this animal was correct, it would have weighed about 1,000kg (2,200lb). 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. [1] The alligator's full mitochondrial genome was sequenced in the 1990s. [137] Allegheny College and San Francisco State University both have Gators as their mascots, as well.[138]. [112] Large bellowing "choruses" of American alligators during the breeding season are commonly initiated by females and perpetuated by males. Even with medical treatment, an American alligator bite may still result in a fatal infection.[126]. There are 29,322 places in the United States. 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. snails) in often equal measure as they did fish. [104], In East Texas, diets were diverse and adult American alligators took mammals, reptiles, amphibians, and invertebrates (e.g. 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. [128] In May 2006, American alligators killed three Floridians in less than a week. Alligators also provide economic benefits through the ecotourism industry. Louisiana There are gators in every part of Louisiana. Their body alone ranges from 6 - 14 feet long. [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. They were removed from "total protection" status in 1987. [44] Most other amniotes are believed to exhibit bidirectional, or tidal breathing. 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. States began monitoring their American alligator populations to ensure that they would continue to grow. Visitors may take swamp tours, in which alligators are a feature. Wiki User . 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 . Oklahoma (100-200) There is a tiny population of alligators that live in certain southern regions of the state. [84] Stomach contents show, among native mammals, muskrats and raccoons are some of the most commonly eaten species. [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. Impacts of the coypu removal program on the diet of American alligators (. 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. [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. TPWD issues the tags, required by state and federal law, based on the alligator population on the privately owned tract. As a result, an adult human can hold an alligator's jaws shut bare-handed. 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. The type of food eaten by alligators depends upon their age and size. 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. In one experiment conducted on the larynx, the fundamental frequency depended on both the glottal gap and stiffness of the larynx tissues. [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 Gatornationals is a NHRA drag race held at the Gainesville Raceway in Gainesville since 1970. However, it is listed as 'threatened by similarity of appearance', and as such, harvest and management is governed by the CITES Treaty (Convention . An easy characteristic to distinguish the two is the fourth tooth. [55] During respiration, air flow is unidirectional, looping through the lungs during inhalation and exhalation;[56] the American alligator's abdominal muscles can alter the position of the lungs within the torso, thus shifting the center of buoyancy, which allows the American alligator to dive, rise, and roll within the water. [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. Alligator hunters, pelt traders, and runaway consumption of Gulf coast marshes: A trophic cascade perspective on coastal wetland losses. [41] The mother defends the nest from predators and assists the hatchlings to water. [22], Water birds, such as herons and egrets, storks, waterfowl and large dabbling rails such as gallinules or coots, are taken when possible. Killed by Max Touchet, a game warden on Marsh Island following an attempted live capture. [73], American alligators modify wetland habitats, most dramatically in flat areas such as the Everglades, by constructing small ponds known as alligator holes. [24] Mother American alligators eventually become more aggressive towards their young, which encourages them to disperse. 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. Gabrey, S. W. 2005. Rootes, W. L., & Chabreck, R. H. (1993). Legal Status. Virginia Living Museum. Juveniles also make a distress call to alert their mothers if they are being threatened. Alligator in captivity The states that have alligators are Florida, Mississippi, Texas, Louisiana, Alabama, North and South Carolina, and Georgia. The Coast Guard spotted another floating south of the Ambrose shipping . The natural sex ratio at hatching is five females to one male. This latest sighting is one of several confirmed sightings of alligators in Southwest Tennessee. 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. (2003). [33], Alligators are generally timid towards humans and tend to walk or swim away if one approaches. Keddy, P.A. Although gators live in these areas, some states have few geographical locations where one can find alligators. No significant difference is noted between the bite forces of male and female American alligators of equal size. The acidity of the stomach has been observed to increase once digestion begins. [20] The majority of American alligators inhabit Florida and Louisiana, with over a million alligators in each state. This behavior has qualified the American alligator to be considered a keystone species. The Florida Naturalist, 41, 27, 6974. 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. 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. The Cuban crocodile, "Trappers catch crocodile in Lake Tarpon," Tampa Bay Times, July 12, 2013. They could survive only in captivity and are few in number. The American alligator is capable of biting through a turtle's shell or a moderately sized mammal bone. [118] Young alligators grow 38in (7.620.3cm) a year and reach adulthood at 6ft (1.8m). 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]. [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. [100] Additionally, American alligators engage in what seems to be cooperative hunting. 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? An alligator with an immobilized tail cannot perform a death roll. Their most important economic benefit to humans may be the control of coypu and muskrats. In Florida, feeding wild alligators at any time is illegal. [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. 2010. [23][125] Alligator bites are serious injuries, due to the reptile's sheer bite force and risk of infection. 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 [115] The female builds a nest of vegetation, sticks, leaves, and mud in a sheltered spot in or near the water. [96][97][98], Occasionally, domestic animals, including dogs, cats, and calves, are taken as available, but are secondary to wild and feral prey. The victim's neighbor can be heard on a 911 call as Gloria Serge was dragged underwater. Sounds ranged from 50 to 1200Hz. [45], The alligator has a similar digestive system to that of the crocodile, with minor differences in morphology and enzyme activity. Large groups of animals bellow together for a few minutes a few times a day, usually one to three hours after sunrise. Since the late 1880s, alligator wrestling has been a source of entertainment for some. [70] This adaptiveness is thought to be why American alligators are widespread further north than the American crocodile. [29], American alligators do not normally reach such extreme sizes. The American alligator was abundant in the pre-drainage Everglades in south Florida. [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. An alligator, or just gator, is a large reptile in the Crocodilia order in the genus Alligator of the family Alligatoridae. Wetland Ecology: Principles and Conservation (2nd edition). Young American alligators eat small fish, frogs, crayfish, and insects. 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. The state that is probably least known for alligator populations is Oklahoma. 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. [48] Some American alligators are missing or have an inhibited gene for melanin, which makes them albino. The breeding season begins in the spring. Sex of alligators is determined by nest temperatures during the middle third of embryo development. [77] This means they are among the first reptiles recorded to use tools. (2010). [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. 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. [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. The American alligator is a relatively large species of crocodilian. American alligator predation on Florida panthers is rare, but has been documented. 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. [57][58] The Aquarium of the Americas in New Orleans has leucistic alligators found in a Louisiana swamp in 1987. Louisiana has the largest alligator population. In 1987, the U.S. Incubation temperatures of 30C (86F) or lower produce a clutch of females; those of 34C (93F) or higher produce entirely males. [66], Nutria were introduced into coastal marshes from South America in the mid-20th century, and their population has since exploded into the millions. [23], American alligators live in freshwater environments, such as ponds, marshes, wetlands, rivers, lakes, and swamps, as well as in brackish water. Eggs are laid in a nest of vegetation, sticks, leaves, and mud in a sheltered spot in or near the water. They may kill larger prey by grabbing it and dragging it into the water to drown. Louisiana What States have alligators? [21][22] A small population is also found in Tamaulipas, in Mexico. Grizzly is observing in the U.S. states of Washington, Idaho, Montana, Wyoming, and Montana. 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? The least populous of the compared places has a population of 383,899. 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 two extant species are the American alligator (A. mississippiensis) and the Chinese alligator (A. sinensis). [20] The majority of American alligators inhabit Florida and Louisiana, with over a million alligators in each state. 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. [24] Hatchlings gather into pods and are guarded by their mother and keep in contact with her through their "yelping" vocalizations. [24] As they grow and develop, the morphology of their teeth and jaws change significantly. The American Alligator population was dramatically reduced by the 1950s and 1960s and a majority of the wild population was likely lost (USFWS 2008). 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. Most animals captured by American alligators are considerably smaller than itself. Fish and Wildlife, both Florida and Louisiana have 1.5 million alligators. Large alligators feed extensively on coypu, and provide a vital ecological service by reducing coypu numbers.[27]. In contrast, air in alligator lungs makes a circuit, moving in only one direction through the parabronchi. 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. While there are rules of thumb for distinguishing alligators from crocodiles, all of them admit exceptions. ", "Alligator hazard is par for the course at Florida golf club", "Enormous alligator spotted on Florida golf course", "How Alligators Survive in a Frozen Pond: They 'Snorkel', "Climbing behaviour in extant crocodilians", "American Alligator Ecology and Monitoring for the Comprehensive Everglades Restoration Plan", "Characterization of Natural and Artificial Alligator Holes", 10.1656/1528-7092(2004)003[0583:CONAAA]2.0.CO;2, WEC203/UW230: Living with Alligators: A Florida Reality, "Crocodiles are cleverer than previously thought: Some crocodiles use lures to hunt their prey", "Alligators Attack and Eat Sharks, Study Confirms", "Alligator mississippiensis (Alligator, Gator, American alligator, Florida alligator, Mississippi alligator, Louisiana alligator. 497 p. Chapter 4. [118] They are preyed on by large fish, birds, raccoons, Florida panthers, and adult American alligators. Historically, hunting had decimated their population, and the American alligator was listed as an endangered species by the Endangered Species Act of 1973. These microorganisms can be found in the high surface area of the mucosa folds of the intestines, as well as throughout the digestive tract. [citation needed], Alligators, much like birds, have been shown to exhibit unidirectional movement of air through their lungs. [41] In Lake Griffin State Park, Florida, adults weighed on average 57.9kg (128lb). [48] The re-circulation of blood leads to higher CO2 concentration as well as lower oxygen affinity. American alligators have 74-80 teeth. F. Wayne King, John Thorbjarnarson and Carlos Yamashita. Critical to the alligator's ability to initiate a death roll, the tail must flex to a significant angle relative to its body. An X-ray revealed that she . This type of protection allowed the alligator population to increase. -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. Coyotes Native to the western 2/3 of the U.S., coyotes began considerably extending their range in the early twentieth century. The modern American alligator is well represented in the fossil record of the Pleistocene. Females rarely exceed 9 feet in length and large females can weigh more than 200 pounds. Craighead, F. C., Sr. (1968). For a tidal breathing animal, such as a mammal, air flows into and out of the lungs through branching bronchi which terminate in small dead-end chambers called alveoli. 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]. 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. 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. The two states that have the most gators are Florida and Louisiana. After the female lays her 20 to 50 white eggs, about the size of a goose egg, she covers them with more vegetation, which heats as it decays, helping to keep the eggs warm. [22][23], During the 19th and 20th centuries, larger males reaching 5 to 6m (16ft 5in to 19ft 8in) were reported. 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 . [89] Rarely, American alligators have been observed killing and eating bobcats, but such events are not common and have little effect on bobcat populations. Cooperative Feeding, A Misinterpreted and Under-Reported Behavior of Crocodilians. [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. Southern Florida is the only place where both alligators and crocodiles live side by side. In 1987, the USFWS removed the animal from the endangered species list, as it was considered to be fully recovered. Such incidents usually involve a panther trying to cross a waterway or coming down to a swamp or river to get a drink. [22] Meanwhile, their undersides are cream-colored. [121], American alligators play an important role in the restoration of the Everglades as biological indicators of restoration success. [52], During brumation the process of digestion experiences changes due to the fasting most alligators experience during these periods of inactivity. The agency annually issues about 2,500 tags, with most of those tags used . [27][28] The largest American alligator scientifically verified in Florida for the period from 1977 to 1993 was reportedly 4.23m (13ft 11in) and weighed 473kg (1,043lb), although another specimen (size estimated from skull) may have measured 4.54m (14ft 11in). Gators remain fully protected in North Carolina, unlike those in eight states from South Carolina to Arkansas and Texas, which allow hunting. [106] Their vocal folds consists of epithelium, lamina propria and muscle. 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. 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. [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. The animal's dark skin is armored with small, bony scales called scutes. Females hatched from eggs incubated at 30C (86F) weigh significantly more than males hatched from eggs incubated at 34C (93F). Hence, Louisiana has had a bounty to try to reduce nutria numbers. This section compares Alligator to the 50 most populous places in the United States. The mating season is in late spring. The American alligator is a large, semi-aquatic, armored reptile that is related to crocodiles. [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. Large male alligators are solitary territorial animals. Herp highlight #1: American alligator. Miami MetroZoo in Florida also has a breeding pair of Chinese alligators. [95] American alligator predation on American black bears has also been recorded. "Alligator hunters, pelt traders, and runaway consumption of Gulf coast marshes: a trophic cascade perspective on coastal wetland losses". 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 state has one million wild alligators and another million on alligator farms. Historically, the American Alligator was common and abundant throughout the southeastern United States. The wild population of Mexican wolves in the United States continued to grow in 2022. Together, these two subfamilies form the family Alligatoridae. 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. The air first enters the outer branch, moves through the parabronchi, and exits the lung through the inner branch. 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. Alligator, Mississippi Population 2023 Population by Race CSV JSON Black or African American White Alligators. Sharks are also known to prey on American alligators, in turn, indicating that encounters between the two predators are common. [18][19], American alligators are found in the southeast United States: all of Florida and Louisiana; the southern parts of Georgia, Alabama, and Mississippi; coastal South and North Carolina; East Texas, the southeast corner of Oklahoma, and the southern tip of Arkansas.
