[108] The American alligator can perform specific vocalizations to declare territory, signal distress, threaten competitors, and locate suitable mates. Morgan, G. S., Richard, F., & Crombie, R. I. In Louisiana, alligators are most common in coastal marshes. Although gators live in these areas, some states have few geographical locations where one can find alligators. 1998. [82][83] As they grow, American alligators gradually expand to larger prey. Alligator hides bring good prices and hides in the 6- to 7-ft range have sold for $300 each. [73], American alligators modify wetland habitats, most dramatically in flat areas such as the Everglades, by constructing small ponds known as alligator holes. The American alligator is a large, semi-aquatic, armored reptile that is related to crocodiles. Gators remain fully protected in North Carolina, unlike those in eight states from South Carolina to Arkansas and Texas, which allow hunting. 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. If fed, the alligators will eventually lose their fear of humans and will learn to associate humans with food.[34]. 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. Coyotes Native to the western 2/3 of the U.S., coyotes began considerably extending their range in the early twentieth century. The wild population of Mexican wolves in the United States continued to grow in 2022. Unexpected effects of predators upon their prey: The case of the American alligator. [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.

[21][22] A small population is also found in Tamaulipas, in Mexico. Miami MetroZoo in Florida also has a breeding pair of Chinese alligators. 115133. [114], American alligators typically live to the age of 50, and possibly over 70 years old. Louisiana has the highest alligator population, approaching 2 million (alligatorfur.com) According to U.S. Females are smaller, measuring 2.6 to 3m (8.5 to 9.8ft) in length. [137] Allegheny College and San Francisco State University both have Gators as their mascots, as well.[138]. [23][125] Alligator bites are serious injuries, due to the reptile's sheer bite force and risk of infection. [95] American alligator predation on American black bears has also been recorded. Young are born with yellow bands around their bodies and are protected by their mother for up to one year.[12]. 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. Biologists recently estimated that the state has between 32,000 and 38,000 alligators, far fewer than either Florida or Louisiana. The sprawl is a forward movement with the belly making contact with the ground and is used to transition to "high walk" or to slither over wet substrate into water. Juveniles can perform a high-pitched hatchling call (a "yelping" trait common to many crocodilian species' hatchling young)[109] to alert their mothers when they are ready to emerge from the nest. [51] Alligators also have highly folded mucosa in the lining of the intestines to further aid in the absorption of nutrients. [117] The female remains near the nest throughout the 65-day incubation period, protecting it from intruders. [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. Fossil alligatoroids have been found throughout Eurasia, because bridges across both the North Atlantic and the Bering Strait connected North America to Eurasia about 66 to 23 Mya. Herp highlight #1: American alligator. [32], Most of the muscle in an alligator's jaw evolved to bite and grip prey. Gabrey, S. W. 2005. (2016, April 30). Like many reptiles, alligators reach a larger size in Florida and other southern latitudes, sometimes reaching 15 feet. Juveniles also make a distress call to alert their mothers if they are being threatened. However, it is listed as 'threatened by similarity of appearance', and as such, harvest and management is governed by the CITES Treaty (Convention . [27], Alligator meat is also consumed by humans.[59][60]. Alligator feeding habits: New data and a review. 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. Wolfe, J. L., D. K. Bradshaw, and R. H. Chabreck. In 1987, the USFWS removed the animal from the endangered species list, as it was considered to be fully recovered. [45] For contrast, the sexual dimorphism of saltwater crocodiles is much more extreme, with mature males nearly twice as long as and at least four times as heavy as female saltwater crocodiles. Alligators first appeared during the Oligocene epoch about 37million years ago. snails) in often equal measure as they did fish. 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. Herpetologica, 99-107. . (1993). American alligators are often less aggressive towards humans than larger crocodile species, a few of which (mainly the Nile and saltwater crocodiles) may prey on humans with some regularity. Legal Status. 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. 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". These microorganisms can be found in the high surface area of the mucosa folds of the intestines, as well as throughout the digestive tract. In the future, possible American alligator populations may be found in areas of Mexico adjacent to the Texas border. Large alligators feed extensively on coypu, and provide a vital ecological service by reducing coypu numbers.[27]. The state has one million wild alligators and another million on alligator farms. Virginia Living Museum. [40], In summer, the female builds a nest of vegetation where the decomposition of the vegetation provides the heat needed to incubate the eggs. Fish and Wildlife Service pronounced the American alligator fully recovered. [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. The two states that have the most gators are Florida and Louisiana. A lone American alligator was spotted for over 10 years living in a river north of Atlanta, Georgia. Males reach sexual maturity at around 11.6 years, and females at around 15.8 years. [88], Other animals may occasionally be eaten, even large deer or feral wild boars, but these are not normally part of the diet. The natural sex ratio at hatching is five females to one male. Alabama is in the outlying part of the American Alligator's range, so the population boom was a bit slower there. Impacts of the coypu removal program on the diet of American alligators (. [29], American alligators do not normally reach such extreme sizes. [20][21], Large male American alligators reach an expected maximum size up to 4.6m (15ft 1in) in length and weighing up to 453kg (999lb), while females reach a maximum of 3m (9ft 10in). In places like South Carolina, the alligator population is now estimated to be as much as 16 times higher than in the mid-1970s. These alligators are practically impossible to find in the wild. In its plan, the state described the alligator population stretching just north of Albemarle Sound and as far west as Robeson County. Alligators that go long enough without a meal during brumation will begin a process called autophagy, where the animal begins to consume its fat reserves to maintain its body weight until it can acquire a sufficient meal. This is not often seen, since if disturbed, they quickly retreat back into the water by jumping from their perch. [59] Louisiana has the largest American alligator population of any U.S. state. 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]. Reproduction [22], Water birds, such as herons and egrets, storks, waterfowl and large dabbling rails such as gallinules or coots, are taken when possible. Alligator mississippiensis Population size 5 Mln Life Span 35-80 yrs Top speed 24 km/h Weight 91-227 kg Length 2.6-3.4 m 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. Such general rules include: Alligator in the Everglades National Park, Alligator in the Canberra Zoo in Australia, Juvenile alligator found in Everglades National Park. [5][6] On rare occasions, a large, old male may grow to an even greater length. 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. As a result, an adult human can hold an alligator's jaws shut bare-handed. 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). Keddy, P.A., L. Gough, J.A. [54] In the water, American alligators swim like fish, moving their pelvic regions and tails from side to side. [66], Nutria were introduced into coastal marshes from South America in the mid-20th century, and their population has since exploded into the millions. Sounds ranged from 50 to 1200Hz. 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. 2010. An X-ray revealed that she . When the jaws are closed, the edges of the upper jaws cover the lower teeth, which fit into the jaws' hollows. 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. There are 29,322 places in the United States. [57][58] The Aquarium of the Americas in New Orleans has leucistic alligators found in a Louisiana swamp in 1987. However, they can not walk on their hind legs. In Florida, feeding wild alligators at any time is illegal. 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. [22], In 2013, American alligators and other crocodilians were reported to also eat fruit. Critical to the alligator's ability to initiate a death roll, the tail must flex to a significant angle relative to its body. The states with the most alligators are Louisiana, Florida, and Alabama. ", "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. [76], American alligators have been documented using lures to hunt prey such as birds. (2003). ", "Alternative Opportunities for Small Farms:Alligator Production Review", "Gator Maters: Florida farmers find lucrative business mating alligators", Why the Gulf Coast needs more big alligators, https://en.wikipedia.org/w/index.php?title=American_alligator&oldid=1142219793, Approximate range of American alligator in the United States. The polar bear lives only in Alaska. [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. When young, alligators eat fish, insects, snails, crustaceans, and worms. -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. Baton Rouge: Louisiana State University Press. 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 . [67] One study of American alligators in north-central Florida found the males preferred open lake water during the spring, while females used both swampy and open-water areas. Georgia The state of Georgia is no stranger to Alligators, and that is particularly true for the southeast quadrant of the state. 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. In 1987, the U.S. For the first time since efforts began to reintroduce the species into the wild, the number of Mexican gray wolves in Arizona and New Mexico has surpassed . [16], The alligator's full mitochondrial genome was sequenced in the 1990s, and it suggests the animal evolved at a rate similar to mammals and greater than birds and most cold-blooded vertebrates. [128] In May 2006, American alligators killed three Floridians in less than a week. This may encourage people to approach alligators and their nests, which can provoke the animals into attacking. [116] The nests built on levees are warmer, thus produce males, while the cooler nests of wet marsh produce females. [64], American alligators are listed under Appendix II of the Convention on International Trade in Endangered Species (CITES) meaning that international trade in the species (including parts and derivatives) is regulated. Southern Florida is the only place where both alligators and crocodiles live side by side. The ontogeny of bite-force performance in American alligator (Alligator mississippiensis). )", "Crocodilian Species - American Alligator (Alligator mississippiensis)". [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. [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). [23] If the size of this animal was correct, it would have weighed about 1,000kg (2,200lb). In this role as a top predator, it may determine the abundance of prey species, including turtles and coypu. Eggs are laid in a nest of vegetation, sticks, leaves, and mud in a sheltered spot in or near the water. This process makes digestion and nutrient absorption easier once the food reaches the second portion of the stomach. [50] American alligators have broad snouts, especially in captive individuals. Male alligators grow faster and larger than females. The state that is probably least known for alligator populations is Oklahoma. On spring nights, American alligators gather in large numbers for group courtship, in the aforementioned "water dances". [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. According to the 2022 annual count, the U.S. population of Mexican wolves has increased, raising the total number of wolves in the wild to a minimum of 241 animals, a 23 percent increase. They could only survive in captivity, as they are very vulnerable to the sun and predators.[49]. The Chinese alligator likely descended from a lineage that crossed the Bering land bridge during the Neogene. American alligator predation on Florida panthers is rare, but has been documented. [63], Historically, hunting and habitat loss have severely affected American alligator populations throughout their range, and whether the species would survive was in doubt. 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 April and May, alligators form so-called "bellowing choruses". The animal's dark skin is armored with small, bony scales called scutes. These states produce a combined annual total of some 45,000 alligator hides. Description American alligators are large crocodilians found only in the United States. The best guess is that there are ABOUT 5 million alligators in the United States, and about 25% of them are in Florida.But they also live in Texas, Louisiana, Mississippi, Alabama, Georgia, the Carolinas and MAYBE even Tennessee. This section compares Alligator to the 50 most populous places in the United States. Unlike the other extinct alligator species of the same genus, the fossil skull was virtually indistinguishable from that of the modern American alligator. This latest sighting is one of several confirmed sightings of alligators in Southwest Tennessee. View Case History American Alligator(1).pdf from FW 350 at Oregon State University, Corvallis. 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. [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. In some cases, larger alligators are known to ambush dogs, Florida panthers and black bears, making them the apex predator throughout their distribution. They may kill larger prey by grabbing it and dragging it into the water to drown. Wetland Ecology: Principles and Conservation (2nd edition). Unusually in these regions, reptiles and amphibians were the most important nonpiscivore prey, mostly turtles and water snakes. American alligators are large crocodilians found only in the United States. [41], In some areas of their range, American alligators are an unusual example of urban wildlife; golf courses are often favoured by the species due to an abundance of water and a frequent supply of prey animals such as fish and birds. They will even consume carrion if they are sufficiently hungry. The victim's neighbor can be heard on a 911 call as Gloria Serge was dragged underwater. Rootes, W. L., & Chabreck, R. H. (1993). Black caiman, Charles, S.; Ross, A. and Garnett, Stephen (1989), Erickson, G. M., Lappin, A. K., & Vliet, K. A. Leidyosuchus of Alberta is the earliest known fossil, from the Campanian era 83 to 72 Mya. The role of the alligator in shaping plant communities and maintaining wildlife in the southern Everglades. In 1807, Georges Cuvier created the genus Alligator;[13] the American alligator and the Chinese alligator are the only extant species in the genus. [65] Females and juveniles are also found in Carolina Bays and other seasonal wetlands. 10. [47], Dorsally, adult American alligators may be olive, brown, gray, or black. [22][23], During the 19th and 20th centuries, larger males reaching 5 to 6m (16ft 5in to 19ft 8in) were reported. This behavior has qualified the American alligator to be considered a keystone species. The USFWS still regulates the legal trade in American alligators and their products to protect still endangered crocodilians that may be passed off as American alligators during trafficking. [3], They inhabit swamps, streams, rivers, ponds, and lakes. pp. [23] Smaller alligators can often be found in large numbers close to each other. Retrieved April 08, 2021, from, Thorbjarnarson, J.

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. [46] Alligators have a two-part stomach, with the first smaller portion containing gastroliths. [47] Once an alligator's meal has been processed it will move on to the second portion of the stomach which is highly acidic. . Additionally, it weighs considerably less, with males rarely over 45kg (100lb). Substantial American alligator populations in the Everglades might be a contributing factor, as a competitor, in keeping the python populations low, preventing the spread of the species north. They are opportunists and their diet is determined largely by both their size and age and the size and availability of prey. The Coast Guard spotted another floating south of the Ambrose shipping . [24] As they grow and develop, the morphology of their teeth and jaws change significantly. There are also nearly 1 million alligators on farms in Louisiana. [84] Stomach contents show, among native mammals, muskrats and raccoons are some of the most commonly eaten species. Females hatched from eggs incubated at 30C (86F) weigh significantly more than males hatched from eggs incubated at 34C (93F). [104], In East Texas, diets were diverse and adult American alligators took mammals, reptiles, amphibians, and invertebrates (e.g. 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. [7], The genus Alligator belongs to the subfamily Alligatorinae, which is the sister taxon to Caimaninae (the caimans). 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. [77] This means they are among the first reptiles recorded to use tools. The high walk is an up-on-four-limbs forward motion used for overland travel with the belly well up from the ground. "Gators" has been the nickname of the University of Florida's sports teams since 1911. The right to left shunt of the heart in alligators means the circulatory system will recirculate blood through the body instead of back to the lungs. [118] Young alligators grow 38in (7.620.3cm) a year and reach adulthood at 6ft (1.8m). 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 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. Benefits include better total health and stronger immune system. may seem too good to be true, but then, some truths are quite incredible in themselves. ] alligator bites are serious injuries, due to the Texas border gators live in these areas some!
