alligator population by state

While there are rules of thumb for distinguishing alligators from crocodiles, all of them admit exceptions. [24] Mother American alligators eventually become more aggressive towards their young, which encourages them to disperse. Virginia Living Museum. 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. In April and May, alligators form so-called "bellowing choruses". [84] Stomach contents show, among native mammals, muskrats and raccoons are some of the most commonly eaten species. 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. The Chinese alligator currently is found in only the Yangtze River valley and parts of adjacent provinces[19] and is extremely endangered, with only a few dozen believed to be left in the wild. [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. [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 least populous of the compared places has a population of 383,899. [23][125] Alligator bites are serious injuries, due to the reptile's sheer bite force and risk of infection. As a result, an adult human can hold an alligator's jaws shut bare-handed. [115] The female builds a nest of vegetation, sticks, leaves, and mud in a sheltered spot in or near the water. [24] American alligators are often mistaken for a similar animal: the American crocodile. Unlike the other extinct alligator species of the same genus, the fossil skull was virtually indistinguishable from that of the modern American alligator.

Incubation temperatures of 30C (86F) or lower produce a clutch of females; those of 34C (93F) or higher produce entirely males. [citation needed], Alligators, much like birds, have been shown to exhibit unidirectional movement of air through their lungs. 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. This page was last edited on 1 March 2023, at 04:33. 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. [53], When on land, an American alligator moves either by sprawling or walking, the latter involving the reptile lifting its belly off the ground. [51] Alligators also have highly folded mucosa in the lining of the intestines to further aid in the absorption of nutrients. [68][69], American alligators are less vulnerable to cold than American crocodiles. Craighead, F. C., Sr. (1968). Both sexes may den underneath banks or clumps of trees during the winter. 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. The American Alligator population was dramatically reduced by the 1950s and 1960s and a majority of the wild population was likely lost (USFWS 2008). Alligators' main prey are smaller animals they can kill and eat with a single bite. Leidyosuchus of Alberta is the earliest known fossil, from the Campanian era 83 to 72 Mya. [10] The largest ever recorded, found in Louisiana, measured 5.84m (19.2ft). [17] However, the full genome, published in 2014, suggests that the alligator evolved much more slowly than mammals and birds.[18]. . 7 min read. Even with medical treatment, an American alligator bite may still result in a fatal infection.[126]. Recently a seven-foot alligator was videoed by TWRA Region 1 personnel in West Tennessee at the Wolf River WMA in Fayette County. Alligators move on land by two forms of locomotion referred to as "sprawl" and "high walk". [79] When hunting terrestrial prey, American alligators may also ambush them from the edge of the water by grabbing them and pulling the prey into the water, the preferred method of predation of larger crocodiles. Large male alligators are solitary territorial animals. 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. The 11 feet-long gator was later captured and killed. 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 . 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. 2010. In its plan, the state described the alligator population stretching just north of Albemarle Sound and as far west as Robeson County. Alligator hides bring good prices and hides in the 6- to 7-ft range have sold for $300 each. [136] The mascot stuck, and was made official in 1911, perhaps because the team captain's nickname was Gator. [5][6] On rare occasions, a large, old male may grow to an even greater length. [75], The teeth of the American alligator are designed to grip prey, but cannot rip or chew flesh like teeth of some other predators (such as canids and felids), and depend on their gizzard, instead, to masticate their food. This type of protection allowed the alligator population to increase. [100] Additionally, American alligators engage in what seems to be cooperative hunting. Historically, the American Alligator was common and abundant throughout the southeastern United States. Additionally, several extinct species of alligator are known from fossil remains. The states with the most alligators are Louisiana, Florida, and Alabama. As the alveoli represent dead-ends to flow, the inspired air must move back out the same way it came in. [25] In Arkansas, a man killed an American alligator that was 4.04m (13ft 3in) and 626kg (1,380lb). Most animals captured by American alligators are considerably smaller than itself. 10. [11] The Chinese alligator is smaller, rarely exceeding 2.1m (7ft) in length. [39] In 2010, on spring nights alligators were found to gather in large numbers for group courtship, the so-called "alligator dances". [24] Hatchlings gather into pods and are guarded by their mother and keep in contact with her through their "yelping" vocalizations. 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. Smaller alligators can often be found in large numbers close to each other. Morgan, G. S., Richard, F., & Crombie, R. I. [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. If fed, the alligators will eventually lose their fear of humans and will learn to associate humans with food.[34]. [123] They may provide a protection service for water birds nesting on islands in freshwater wetlands. The baby alligator's egg tooth helps it get out of its egg during hatching time. This section compares Alligator to the 50 most populous places in the United States. 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. Alligator feeding habits: New data and a review. [104], In East Texas, diets were diverse and adult American alligators took mammals, reptiles, amphibians, and invertebrates (e.g. 1987. Cambridge University Press, Cambridge, UK. Critical to the alligator's ability to initiate a death roll, the tail must flex to a significant angle relative to its body. [24] As they grow and develop, the morphology of their teeth and jaws change significantly. [114], American alligators typically live to the age of 50, and possibly over 70 years old. [99] [89] Rarely, American alligators have been observed killing and eating bobcats, but such events are not common and have little effect on bobcat populations. Studies have found that eggs hatched at a temperature below 88.7F or a temperature above 94.1F will produce female offspring, while those at a temperature between 90.5F to 92.3F will produce male offspring. They are grouped in the family Alligatoridae with the caimans. The role of the alligator in shaping plant communities and maintaining wildlife in the southern Everglades. Herp highlight #1: American alligator. . 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. [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. Dundee, H. A., and D. A. Rossman. 911 Call Reveals Moments After Gator Attacks Elderly Woman. [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. Alligators. This may encourage people to approach alligators and their nests, which can provoke the animals into attacking. [106] Their vocal folds consists of epithelium, lamina propria and muscle. 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. Louisiana and Florida. It is enclosed in a pocket in the upper jaw. Cannibalism in the American alligator. [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. [21] [22] A small population is also found in Tamaulipas, in Mexico. The American alligator is a relatively large species of crocodilian. This listing has been adopted by the State of Florida. Their body alone ranges from 6 - 14 feet long.

The state has a "healthy and stable population" of about 1.3 million alligators of every size, but the most common range in size from 4-12 feet. Subsequent conservation efforts have allowed their numbers to increase and the species was removed from endangered status in 1987. This process makes digestion and nutrient absorption easier once the food reaches the second portion of the stomach. Florida . 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? 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. 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). Additionally, it weighs considerably less, with males rarely over 45kg (100lb). [110] Males are known to use infrasound during mating bellows. Indeed, far more Chinese alligators live in zoos around the world than can be found in the wild. [121], American alligators play an important role in the restoration of the Everglades as biological indicators of restoration success. 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. [47], Dorsally, adult American alligators may be olive, brown, gray, or black. 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. Sharks are also known to prey on American alligators, in turn, indicating that encounters between the two predators are common. The sex of the offspring is determined by the temperature in the nest and is fixed within seven to 21 days of the start of incubation. Juveniles also make a distress call to alert their mothers if they are being threatened. Members of this superfamily first arose in the late Cretaceous, about 10065 million years ago (Mya). [57][58] The Aquarium of the Americas in New Orleans has leucistic alligators found in a Louisiana swamp in 1987. [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. Estimated to be between 426.72cm and 457.2cm when spotted. [127] Only nine fatal attacks occurred in the United States throughout the 1970s1990s, but American alligators killed 12 people between 2001 and 2007. "Alligator hunters, pelt traders, and runaway consumption of Gulf coast marshes: a trophic cascade perspective on coastal wetland losses". By balancing sticks and branches on their heads, American alligators are able to lure birds looking for suitable nesting material to kill and consume. [72], American alligators primarily bask on shore, but also climb into and perch on tree limbs to bask if no shoreline is available. Females rarely exceed 9 feet in length and large females can weigh more than 200 pounds. They are opportunists and their diet is determined largely by both their size and age and the size and availability of prey. When young, alligators eat fish, insects, snails, crustaceans, and worms. American alligators prevent predatory mammals from reaching island-based rookeries and in return eat spilled food and birds that fall from their nests. 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. [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. It is common to use several wraps of duct tape to prevent an adult alligator from opening its jaws when being handled or transported. snails) in often equal measure as they did fish. American alligators are apex predators and consume fish, amphibians, reptiles, birds, and mammals. [46] Alligators have a two-part stomach, with the first smaller portion containing gastroliths. [22], Water birds, such as herons and egrets, storks, waterfowl and large dabbling rails such as gallinules or coots, are taken when possible. When the jaws are closed, the edges of the upper jaws cover the lower teeth, which fit into the jaws' hollows. The Chinese alligator likely descended from a lineage that crossed the Bering land bridge during the Neogene. 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]. 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. Alligators generally mature at a length of 1.8m (6ft). Georgia The state of Georgia is no stranger to Alligators, and that is particularly true for the southeast quadrant of the state. 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. The two extant species are the American alligator (A. mississippiensis) and the Chinese alligator (A. sinensis). [58] They are found in parts of North Carolina, South Carolina, Georgia, Florida, Louisiana, Alabama, Mississippi, Arkansas, Oklahoma and Texas. Ecosystems 2: 4963. 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]. Grizzly is observing in the U.S. states of Washington, Idaho, Montana, Wyoming, and Montana. The bellows of male American alligators are accompanied by powerful blasts of infrasound. This latest sighting is one of several confirmed sightings of alligators in Southwest Tennessee. [112] Large bellowing "choruses" of American alligators during the breeding season are commonly initiated by females and perpetuated by males. [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. Alligators consume food that cannot be eaten in one bite by allowing it to rot or by biting and then performing a "death roll", spinning or convulsing wildly until bite-sized chunks are torn off. [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. Description American alligators are large crocodilians found only in the United States. Eggs are laid in a nest of vegetation, sticks, leaves, and mud in a sheltered spot in or near the water. Louisiana There are gators in every part of Louisiana. For the history, the United States is the only nation on earth where both alligators and . 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. [118] Young alligators grow 38in (7.620.3cm) a year and reach adulthood at 6ft (1.8m). An alligator measuring 19 ft. 2 in. [21][22] A small population is also found in Tamaulipas, in Mexico. 497 p. Chapter 4. Although gators live in these areas, some states have few geographical locations where one can find alligators. They were removed from "total protection" status in 1987. (2003). 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.
