alligator population by state22 Apr alligator population by state

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 . 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. 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. [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. [24] As they grow and develop, the morphology of their teeth and jaws change significantly. 10. They are grouped in the family Alligatoridae with the caimans. [35][36] Their stomachs also often contain gizzard stones. (1993). [68][69], American alligators are less vulnerable to cold than American crocodiles. In its plan, the state described the alligator population stretching just north of Albemarle Sound and as far west as Robeson County. 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. Hatchlings feed mostly on invertebrates. [33], Alligators are generally timid towards humans and tend to walk or swim away if one approaches. [2] Later English spellings of the name included allagarta and alagarto. [137] Allegheny College and San Francisco State University both have Gators as their mascots, as well.[138]. (2010). [50][48] The alligator's metabolism will also increase after a meal by up to four times its basal metabolic rate. [135] Several organizations and products from Florida have been named after the animal. Additionally, several extinct species of alligator are known from fossil remains. Smaller alligators can often be found in large numbers close to each other. [26] Farther west, in Louisiana, heavy grazing by coypu and muskrat are causing severe damage to coastal wetlands. 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. Sex of alligators is determined by nest temperatures during the middle third of embryo development. 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. [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. [66], Nutria were introduced into coastal marshes from South America in the mid-20th century, and their population has since exploded into the millions. The Cuban crocodile, "Trappers catch crocodile in Lake Tarpon," Tampa Bay Times, July 12, 2013. The American alligator is the official state reptile of Florida,[133] Louisiana,[134] and Mississippi. In 1987, the USFWS removed the animal from the endangered species list, as it was considered to be fully recovered. [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. 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. The American alligator was abundant in the pre-drainage Everglades in south Florida. 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. Females are smaller, measuring 2.6 to 3m (8.5 to 9.8ft) in length. This listing has been adopted by the State of Florida. [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. They may kill larger prey by grabbing it and dragging it into the water to drown. Critical to the alligator's ability to initiate a death roll, the tail must flex to a significant angle relative to its body. [23][125] Alligator bites are serious injuries, due to the reptile's sheer bite force and risk of infection. Herp highlight #1: American alligator. For example, one long-term mark-recapture study (1979-2015) done at the Tom Yawkey Wildlife Center in South Carolina found evidence to support patterns of determinate growth, with growth ceasing upon reaching a certain age (43 years for males and 31 years for females). [47], Dorsally, adult American alligators may be olive, brown, gray, or black. As the alveoli represent dead-ends to flow, the inspired air must move back out the same way it came in. Alligator attacks an 85 year-old grandmother walking her dog in a retirement community in Fort Pierce, Florida. In one experiment conducted on the larynx, the fundamental frequency depended on both the glottal gap and stiffness of the larynx tissues. Legal Status. [46] Alligators have a two-part stomach, with the first smaller portion containing gastroliths. [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. Males reach sexual maturity at around 11.6 years, and females at around 15.8 years. [25] In Arkansas, a man killed an American alligator that was 4.04m (13ft 3in) and 626kg (1,380lb). 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. may seem too good to be true, but then, some truths are quite incredible in themselves. [24] When they construct alligator holes in the wetlands, they increase plant diversity and provide habitat for other animals during droughts. When the jaws are closed, the edges of the upper jaws cover the lower teeth, which fit into the jaws' hollows. Description American alligators are large crocodilians found only in the United States. However alligators are still vulnerable to microbial infections despite the immune boost from other microbiota. [12], No average lifespan for an alligator has been measured. 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). 1989. They could only survive in captivity, as they are very vulnerable to the sun and predators.[49]. The conservation status of the American alligator is listed as Least Concern by the International Union for Conservation of Nature. [95] American alligator predation on American black bears has also been recorded. Keddy, P.A. [53], When on land, an American alligator moves either by sprawling or walking, the latter involving the reptile lifting its belly off the ground. [7], The genus Alligator belongs to the subfamily Alligatorinae, which is the sister taxon to Caimaninae (the caimans). Hatchlings mostly feed on invertebrates such as insects, insect larvae, snails, spiders, and worms, as well as small fish and frogs. [54], Like other crocodilians, alligators have an armor of bony scutes. [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). [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. 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. [59] Louisiana has the largest American alligator population of any U.S. state. It is common to use several wraps of duct tape to prevent an adult alligator from opening its jaws when being handled or transported. It is enclosed in a pocket in the upper jaw. Some 23 dead whales have washed ashore along the East Coast since early December, including 12 in New Jersey and New York. [11] The Chinese alligator is smaller, rarely exceeding 2.1m (7ft) in length. [100] Additionally, American alligators engage in what seems to be cooperative hunting. [57][58] The Aquarium of the Americas in New Orleans has leucistic alligators found in a Louisiana swamp in 1987. This information helps TPWD determine trends in the population, assess alligator habitat and establish wise hunting limits for the species. This marks the seventh consecutive year of growth in the wild population. [52], During brumation the process of digestion experiences changes due to the fasting most alligators experience during these periods of inactivity. 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. Cambridge University Press, Cambridge, UK. Bellowing is performed in a "head oblique, tail arched" posture. ", http://www.flmnh.ufl.edu/herpetology/links/cooperative-feeding, "Demographic and geographic variation in food habits of American alligators (, "Subglottal pressure and fundamental frequency control in contact calls of juvenile Alligator mississippiensis", "Functional morphology of the Alligator mississippiensis larynx with implications for vocal production", https://defenders.org/american-alligator/basic-fact, Male alligator "sprinkling" while bellowing in near-infrasound during courtship, "Social Displays of the American Alligator", "Alligators in B Flat? [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. Louisiana There are gators in every part of Louisiana. [19] Weight varies considerably depending on length, age, health, season, and available food sources. Alligator holes are an oasis during the Everglades dry season, so are consequently important foraging sites for other organisms. [39] In 2010, on spring nights alligators were found to gather in large numbers for group courtship, the so-called "alligator dances". [72], American alligators primarily bask on shore, but also climb into and perch on tree limbs to bask if no shoreline is available. The state has one million wild alligators and another million on alligator farms. Such incidents usually involve a panther trying to cross a waterway or coming down to a swamp or river to get a drink. Alligators in the wild can live up to 70 years; some in captivity may live even longer. Alligators move on land by two forms of locomotion referred to as "sprawl" and "high walk". [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. Georgia The state of Georgia is no stranger to Alligators, and that is particularly true for the southeast quadrant of the state. 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. A lone American alligator was spotted for over 10 years living in a river north of Atlanta, Georgia. [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. 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. An X-ray revealed that she . [23], American alligators live in freshwater environments, such as ponds, marshes, wetlands, rivers, lakes, and swamps, as well as in brackish water. [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. [118] They are preyed on by large fish, birds, raccoons, Florida panthers, and adult American alligators. Their most important economic benefit to humans may be the control of coypu and muskrats. -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. Like many reptiles, alligators reach a larger size in Florida and other southern latitudes, sometimes reaching 15 feet. [17] However, the full genome, published in 2014, suggests that the alligator evolved much more slowly than mammals and birds.[18]. Adult alligators are black or dark olive-brown with white undersides, while juveniles have bright yellow or whitish stripes which sharply contrast against their dark hides, providing them additional camouflage amongst reeds and wetland grasses. 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. Fish and Wildlife Service pronounced the American alligator fully recovered. [15] In 2016, a Miocene (about 23 to 5.3 Mya) fossil skull of an alligator was found at Marion County, Florida. Rootes, W. L., & Chabreck, R. H. (1993). Fish and Wildlife, both Florida and Louisiana have 1.5 million alligators. "Gators" has been the nickname of the University of Florida's sports teams since 1911. 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. Alligator feeding habits: New data and a review. Occasionally, unwary adult birds are grabbed and eaten by American alligators, but most predation on bird species occurs with unsteady fledgling birds in late summer, as fledgling birds attempt to make their first flights near the water's edge. Alligators. [22], Additionally, American alligators have recently been filmed and documented killing and eating sharks and rays; four incidents documented indicated that bonnetheads, lemon sharks, Atlantic stingrays, and nurse sharks are components of the animal's diet. The acidity of the stomach has been observed to increase once digestion begins. Louisiana has the highest alligator population, approaching 2 million (alligatorfur.com) According to U.S. [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. Both males and females bellow loudly by sucking air into their lungs and blowing it out in intermittent, deep-toned roars to attract mates and declare territory. [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). By the way, Florida declared the alligator their official state reptile in 1987. In NC, males can reach 13 feet and weigh up to 500 pounds or more. The two kinds of white alligators are albino and leucistic.

In 1987, the U.S. Louisiana What States have alligators? She will provide protection to the young for about a year if they remain in the area. [124], American alligators are capable of killing humans, but fatal attacks are fairly rare. Adult alligators regularly cannibalize younger individuals, though estimates of the rate of cannibalism vary widely. [29], American alligators do not normally reach such extreme sizes. [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. They could survive only in captivity and are few in number. [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. 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. They cause serious damage to coastal marshes and may dig burrows in levees. [80][81], American alligators are considered an apex predator throughout their range. Killed by Max Touchet, a game warden on Marsh Island following an attempted live capture. [64], Both the United States Fish and Wildlife Service (USFWS) and state wildlife agencies in the South contributed to the American alligator's recovery. The victim's neighbor can be heard on a 911 call as Gloria Serge was dragged underwater. These states produce a combined annual total of some 45,000 alligator hides. (2003). [76], American alligators have been documented using lures to hunt prey such as birds. Sharks are also known to prey on American alligators, in turn, indicating that encounters between the two predators are common. Alligators have muscular, flat tails that propel them while swimming. [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. Alligator hunters, pelt traders, and runaway consumption of Gulf coast marshes: A trophic cascade perspective on coastal wetland losses. Its front feet have 5 toes, while rear feet have 4 toes that are webbed. The folds result in greater surface area for the nutrients to be absorbed through. Coyotes Native to the western 2/3 of the U.S., coyotes began considerably extending their range in the early twentieth century. Unusually in these regions, reptiles and amphibians were the most important nonpiscivore prey, mostly turtles and water snakes. 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]. and early 1960's, but protective action by state and federal governments helped keep them from disappearing completely. The bellows of male American alligators are accompanied by powerful blasts of infrasound. [73], American alligators modify wetland habitats, most dramatically in flat areas such as the Everglades, by constructing small ponds known as alligator holes. Oklahoma is home to between 100-200 individuals, but they constitute a stable population. Young are born with yellow bands around their bodies and are protected by their mother for up to one year.[12]. The least populous of the compared places has a population of 383,899. 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.
