[80][81], American alligators are considered an apex predator throughout their range. The polar bear lives only in Alaska. [32], Most of the muscle in an alligator's jaw evolved to bite and grip prey. The American Alligator population was dramatically reduced by the 1950s and 1960s and a majority of the wild population was likely lost (USFWS 2008). The American alligator is a relatively large species of crocodilian. Young are born with yellow bands around their bodies and are protected by their mother for up to one year.[12]. [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. 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. [44], While noticeable in very mature specimens, the sexual dimorphism in size of the American alligator is relatively modest among crocodilians. Its front feet have 5 toes, while rear feet have 4 toes that are webbed. Hence, Louisiana has had a bounty to try to reduce nutria numbers. [11] Male American alligators use infrasound to attract females. (2016, April 30). Oklahoma is home to between 100-200 individuals, but they constitute a stable population. Protection under the Endangered Species Act allowed the species to recuperate in many areas where it had been depleted. Subsequent conservation efforts have allowed their numbers to increase and the species was removed from endangered status in 1987. [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 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. The states with the most alligators are Louisiana, Florida, and Alabama. [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. In this role as a top predator, it may determine the abundance of prey species, including turtles and coypu. Louisiana has the largest alligator population. [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. 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. 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. There are 29,322 places in the United States. They are grouped in the family Alligatoridae with the caimans. States began monitoring their American alligator populations to ensure that they would continue to grow. [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. The below cladogram shows the phylogeny of alligators. Keddy PA, Gough L, Nyman JA, McFalls T, Carter J, Siegnist J (2009). 497 p. Chapter 4. Alligators, unlike the large crocodiles, do not immediately regard a human upon encounter as prey, but may still attack in self-defense if provoked. In Florida, feeding wild alligators at any time is illegal. [3], They inhabit swamps, streams, rivers, ponds, and lakes. 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. Herpetologica, 99-107. 9 p. Available at: McLaughlin, Eliott C.; Almasy, Steve and Shoichet, Catherine E. (2016-06-16), International Union for Conservation of Nature, Convention on International Trade in Endangered Species, List of fatal alligator attacks in the United States, Florida Department of Agriculture and Consumer Services, "Phylogenetic analysis of a new morphological dataset elucidates the evolutionary history of Crocodylia and resolves the long-standing gharial problem", 10.2305/IUCN.UK.2019-2.RLTS.T46583A3009637.en, American Alligators, American Alligator Pictures, American Alligator Facts National Geographic, https://thevlm.org/herp-highlight-1-american-alligator/, "Social Displays of the American Alligator (, "Phylogenetic approach toward crocodylian history", "The complete mitochondrial genome of Alligator mississippiensis and the separation between recent archosauria (birds and crocodiles)", "Three crocodilian genomes reveal ancestral patterns of evolution among archosaurs", 10.1638/1042-7260(2000)031[0303:mamawa]2.0.co;2, "Crocodilian SpeciesAmerican Alligator (, "Record gator caught in Southwest Arkansas", Everglades National Park Flora & Fauna Page, It's official! [89] Rarely, American alligators have been observed killing and eating bobcats, but such events are not common and have little effect on bobcat populations. Sounds ranged from 50 to 1200Hz. 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. 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. Large groups of animals bellow together for a few minutes a few times a day, usually one to three hours after sunrise. On average, it is the largest species in the family Alligatoridae, with only the black caiman being possibly longer. [73], American alligators modify wetland habitats, most dramatically in flat areas such as the Everglades, by constructing small ponds known as alligator holes. 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. Louisiana There are gators in every part of Louisiana. Throughout the year (in particular during the breeding season), American alligators bellow to declare territory, and locate suitable mates. Baton Rouge: Louisiana State University Press. An X-ray revealed that she . They may kill larger prey by grabbing it and dragging it into the water to drown. [41] In Lake Griffin State Park, Florida, adults weighed on average 57.9kg (128lb). [37][27] As humans encroach into their habitat, attacks are few but not unknown. The American alligator is classified by the US Fish and Wildlife Service as similarity of appearance to a threatened taxon. 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 . Today, alligator farming is a large, growing industry in Georgia, Florida, Texas, and Louisiana. may seem too good to be true, but then, some truths are quite incredible in themselves. 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. Males rarely exceed 13 feet in length and large males can weigh well over 500 pounds. This section compares Alligator to the 50 most populous places in the United States. The Mississippi Department of Wildlife, Fisheries and Parks (MDWFP) runs an annual alligator survey along approximately 317 miles of waterways on 15 routes in 13 counties. Historically, hunting had decimated their population, and the American alligator was listed as an endangered species by the Endangered Species Act of 1973. Unexpected effects of predators upon their prey: The case of the American alligator. [52], During brumation the process of digestion experiences changes due to the fasting most alligators experience during these periods of inactivity. [58] They are found in parts of North Carolina, South Carolina, Georgia, Florida, Louisiana, Alabama, Mississippi, Arkansas, Oklahoma and Texas. By 1960, however, alligators had been completely eliminated from much of their former range. Most animals captured by American alligators are considerably smaller than itself. These American alligators are extremely rare and almost impossible to find in the wild. [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. The state that is probably least known for alligator populations is Oklahoma. Population by Place in the United States. Gabrey, S. W. 2005. [23] 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. 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. [24] Hatchlings gather into pods and are guarded by their mother and keep in contact with her through their "yelping" vocalizations. These microorganisms can be found in the high surface area of the mucosa folds of the intestines, as well as throughout the digestive tract. 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. [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. Their most important economic benefit to humans may be the control of coypu and muskrats. While there are rules of thumb for distinguishing alligators from crocodiles, all of them admit exceptions. 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). Additionally, several extinct species of alligator are known from fossil remains. Created by the Miccosukee and Seminole tribes prior to the arrival of Europeans, this tourism tradition remains popular despite criticism from animal-rights activists.[130]. [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. Alligators can be legally taken only . "Alligator hunters, pelt traders, and runaway consumption of Gulf coast marshes: a trophic cascade perspective on coastal wetland losses". 10. Both sexes may den underneath banks or clumps of trees during the winter. [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. . Adult American alligators can growl, hiss, or cough to threaten others and declare territory. [20] The majority of American alligators inhabit Florida and Louisiana, with over a million alligators in each state. [54] In the water, American alligators swim like fish, moving their pelvic regions and tails from side to side. This type of protection allowed the alligator population to increase. Morgan, G. S., Richard, F., & Crombie, R. I. [11] The Chinese alligator is smaller, rarely exceeding 2.1m (7ft) in length. 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. 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. In places like South Carolina, the alligator population is now estimated to be as much as 16 times higher than in the mid-1970s. The Amphibians and Reptiles of Louisiana. Females rarely exceed 9 feet in length and large females can weigh more than 200 pounds. [2] Later English spellings of the name included allagarta and alagarto. [95] American alligator predation on American black bears has also been recorded. 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 What States have alligators? Biologists recently estimated that the state has between 32,000 and 38,000 alligators, far fewer than either Florida or Louisiana. [7], The genus Alligator belongs to the subfamily Alligatorinae, which is the sister taxon to Caimaninae (the caimans). Cannibalism in the American alligator. [52], Alligators also have complex microbiomes that are not fully understood yet, but can be attributed to both benefits and costs to the animal. [117] The female remains near the nest throughout the 65-day incubation period, protecting it from intruders. 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. An easy characteristic to distinguish the two is the fourth tooth. This is not often seen, since if disturbed, they quickly retreat back into the water by jumping from their perch. 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. [47], Dorsally, adult American alligators may be olive, brown, gray, or black. Alligator attacks often happen when . Alligator, Mississippi Population 2023 Population by Race CSV JSON Black or African American White Leidyosuchus of Alberta is the earliest known fossil, from the Campanian era 83 to 72 Mya. Sex of alligators is determined by nest temperatures during the middle third of embryo development. The type of food eaten by alligators depends upon their age and size.

Impacts of the coypu removal program on the diet of American alligators (. Females generally grow to less than 9 feet and weigh up to 200 pounds. [115] The female builds a nest of vegetation, sticks, leaves, and mud in a sheltered spot in or near the water. 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. [15] In 2016, a Miocene (about 23 to 5.3 Mya) fossil skull of an alligator was found at Marion County, Florida. They play an important role as ecosystem engineers in wetland ecosystems through the creation of alligator holes, which provide both wet and dry habitats for other organisms. No significant difference is noted between the bite forces of male and female American alligators of equal size. [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. Gatorland's denizens roar in ecstasy", "Spatial and temporal variation in nest temperatures forecasts sex ratio skews in a crocodilian with environmental sex determination", Python explodes after swallowing 6-foot alligator in Florida Everglades, USGS Maps Show Potential Non-Native Python Habitat Along Three U.S. The sprawling of American alligators and other crocodylians is not similar to that of salamanders and lizards, being similar to walking. They are opportunists and their diet is determined largely by both their size and age and the size and availability of prey. Alligator hunters, pelt traders, and runaway consumption of Gulf coast marshes: A trophic cascade perspective on coastal wetland losses. The Florida Naturalist, 41, 27, 6974. [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. In NC, males can reach 13 feet and weigh up to 500 pounds or more. [22], In 2013, American alligators and other crocodilians were reported to also eat fruit. As a result, an adult human can hold an alligator's jaws shut bare-handed. 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. Alligator feeding habits: New data and a review. snails) in often equal measure as they did fish. [50] Juveniles have small, needle-like teeth that become much more robust and narrow snouts that become broader as the individuals develop. [51] Alligators also have highly folded mucosa in the lining of the intestines to further aid in the absorption of nutrients. Fish and Wildlife Service pronounced the American alligator fully recovered. They were removed from "total protection" status in 1987. [86], Recently, a population of Burmese pythons became established in Everglades National Park. pp. However alligators are still vulnerable to microbial infections despite the immune boost from other microbiota. Most American alligators eat a wide variety of animals, including invertebrates, fish, birds, turtles, snakes, amphibians, and mammals. However, they can not walk on their hind legs. 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. [1] The alligator's full mitochondrial genome was sequenced in the 1990s. For the history, the United States is the only nation on earth where both alligators and . This information helps TPWD determine trends in the population, assess alligator habitat and establish wise hunting limits for the species. [124], American alligators are capable of killing humans, but fatal attacks are fairly rare. Females are produced at temperatures less than 31.5oC; mixed sex ratios occur at 32oC, and males only are produced when temperatures are between 32.5 and 33oC. 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. Alabama is in the outlying part of the American Alligator's range, so the population boom was a bit slower there. American alligators also may control the long-term vegetation dynamics in wetlands by reducing the population of small mammals, particularly coypu, which may otherwise overgraze marsh vegetation. Members of this superfamily first arose in the late Cretaceous, about 10065 million years ago (Mya). 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]. Benefits include better total health and stronger immune system. [27], Alligator meat is also consumed by humans.[59][60]. 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. Louisiana harvested about 30,000 alligators last year--a number almost equivalent to the entire Mississippi alligator population. [39] In 2010, on spring nights alligators were found to gather in large numbers for group courtship, the so-called "alligator dances". [104], In East Texas, diets were diverse and adult American alligators took mammals, reptiles, amphibians, and invertebrates (e.g. 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. Juveniles also make a distress call to alert their mothers if they are being threatened. Killed by Max Touchet, a game warden on Marsh Island following an attempted live capture. Alligators' main prey are smaller animals they can kill and eat with a single bite. The victim's neighbor can be heard on a 911 call as Gloria Serge was dragged underwater. [106] Their vocal folds consists of epithelium, lamina propria and muscle. [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. American alligators prevent predatory mammals from reaching island-based rookeries and in return eat spilled food and birds that fall from their nests. [135] Several organizations and products from Florida have been named after the animal. Male alligators grow faster and larger than females. 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 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. This marks the seventh consecutive year of growth in the wild population. [94] During summer, males still preferred open water, while females remained in the swamps to construct their nests and lay their eggs. In April and May, alligators form so-called "bellowing choruses". Alligator attacks an 85 year-old grandmother walking her dog in a retirement community in Fort Pierce, Florida. The natural sex ratio at hatching is five females to one male. [22] Meanwhile, their undersides are cream-colored. 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. This latest sighting is one of several confirmed sightings of alligators in Southwest Tennessee. [65] Females and juveniles are also found in Carolina Bays and other seasonal wetlands. When young, alligators eat fish, insects, snails, crustaceans, and worms. [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. Virginia Living Museum. Dundee, H. A., and D. A. Rossman. [123] They may provide a protection service for water birds nesting on islands in freshwater wetlands. [50] American alligators have broad snouts, especially in captive individuals. The air first enters the outer branch, moves through the parabronchi, and exits the lung through the inner branch. The American alligator was first classified by French zoologist Franois Marie Daudin as Crocodilus mississipiensis in 1801. Alligators generally mature at a length of 1.8m (6ft). It has more alligators than any other state. She will provide protection to the young for about a year if they remain in the area. [118] Young alligators grow 38in (7.620.3cm) a year and reach adulthood at 6ft (1.8m). [50] Another study noted that as the American alligator increases in size, the force of its bite also increases. Louisiana has the largest alligator population. Georgia The state of Georgia is no stranger to Alligators, and that is particularly true for the southeast quadrant of the state. 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? [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. [19] Weight varies considerably depending on length, age, health, season, and available food sources. 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. Keddy, P.A. 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. American alligators are large crocodilians found only in the United States. [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. Whenever an American alligator's mouth is closed, the fourth tooth is no longer visible. This differs from Nile crocodiles, which lay their eggs in pits. In 1987, the U.S. The acidity of the stomach has been observed to increase once digestion begins. Southern Florida is the only place where both alligators and crocodiles live side by side. 2010. An alligator measuring 19 ft. 2 in. 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. [25] In Arkansas, a man killed an American alligator that was 4.04m (13ft 3in) and 626kg (1,380lb). [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. [23] If the size of this animal was correct, it would have weighed about 1,000kg (2,200lb). [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). 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. 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. Indeed, far more Chinese alligators live in zoos around the world than can be found in the wild. Fossils identical to the existing American alligator are found throughout the Pleistocene, from 2.5 million to 11.7 thousand years ago. Southern Florida is the only place where both alligators and crocodiles live side by side. [64], Both the United States Fish and Wildlife Service (USFWS) and state wildlife agencies in the South contributed to the American alligator's recovery. Alligators are naturally expanding their range into Tennessee from the southern border states. 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.
