[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. Alligator holes are an oasis during the Everglades dry season, so are consequently important foraging sites for other organisms. 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. [27], Alligator meat is also consumed by humans.[59][60]. 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. 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. They may kill larger prey by grabbing it and dragging it into the water to drown. [24] As they grow and develop, the morphology of their teeth and jaws change significantly. Crocodilians are the most vocal of all non-avian reptiles and have a variety of different calls depending on the age, size, and sex of the animal. ", "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. In Florida, feeding wild alligators at any time is illegal. 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. [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. 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.

Sex of alligators is determined by nest temperatures during the middle third of embryo development. Adult American alligators held the record as having the strongest laboratory-measured bite of any living animal, measured at up to 13,172N (1,343.2kgf; 2,961lbf). Visitors may take swamp tours, in which alligators are a feature. The alligator is no longer endangered. 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 Throughout the year (in particular during the breeding season), American alligators bellow to declare territory, and locate suitable mates. 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. 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. Members of this superfamily first arose in the late Cretaceous, about 10065 million years ago (Mya). American Alligator (Alligator mississippiensis) An ESA success story Photo: Expert Help. The American alligator is the official state reptile of Florida,[133] Louisiana,[134] and Mississippi. Its front feet have 5 toes, while rear feet have 4 toes that are webbed. [25] In Arkansas, a man killed an American alligator that was 4.04m (13ft 3in) and 626kg (1,380lb). Alligators, unlike the large crocodiles, do not immediately regard a human upon encounter as prey, but may still attack in self-defense if provoked. The ontogeny of bite-force performance in American alligator (Alligator mississippiensis). These items help the American alligator in the process of digestion by crushing up the meat and bones of animals, especially animals with shells. [41] In Lake Griffin State Park, Florida, adults weighed on average 57.9kg (128lb). The mating season is in late spring. Sounds ranged from 50 to 1200Hz. They cause serious damage to coastal marshes and may dig burrows in levees. [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. [21] [22] A small population is also found in Tamaulipas, in Mexico. The state has one million wild alligators and another million on alligator farms. 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). Coasts, "The American Alligator: An Indicator Species for Everglades Restoration", "Nesting Island Creation for Wading Birds", Crocodile and Alligator Differences Animal Facts for Kids, Disney alligator attack: Resort to add warning signs, source says, 10.1580/1080-6032(2005)16[119:AAOHIT]2.0.CO;2, "A String of Deaths by Gators in Florida", "Alligator wrestling cruelty or tradition? However alligators are still vulnerable to microbial infections despite the immune boost from other microbiota. snails) in often equal measure as they did fish. The species is the official state reptile of three states: Florida, Louisiana, and Mississippi. The animal's dark skin is armored with small, bony scales called scutes. [39] In 2010, on spring nights alligators were found to gather in large numbers for group courtship, the so-called "alligator dances". [22][23], During the 19th and 20th centuries, larger males reaching 5 to 6m (16ft 5in to 19ft 8in) were reported. However, these claims are largely based on assumptions and observations of juvenile and young adult crocodilians, and recent studies are beginning to contradict this claim. Some 23 dead whales have washed ashore along the East Coast since early December, including 12 in New Jersey and New York. 2010. 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. They were removed from "total protection" status in 1987. [100] Additionally, American alligators engage in what seems to be cooperative hunting. [106] Their vocal folds consists of epithelium, lamina propria and muscle. [118] They are preyed on by large fish, birds, raccoons, Florida panthers, and adult American alligators. [136] The mascot stuck, and was made official in 1911, perhaps because the team captain's nickname was Gator. [24] The largest reported individual size was a male killed in 1890 on Marsh Island, Louisiana, and reportedly measured at 5.84m (19ft 2in) in length, but no voucher specimen was available, since the American alligator was left on a muddy bank after having been measured due to having been too massive to relocate. [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. 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]. This behavior has qualified the American alligator to be considered a keystone species. [10] It is distinguished from the sympatric American crocodile by its broader snout, with overlapping jaws and darker coloration, and is less tolerant of saltwater but more tolerant of cooler climates than the American crocodile, which is found only in tropical and warm subtropical climates. 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. The American alligator was first classified by French zoologist Franois Marie Daudin as Crocodilus mississipiensis in 1801. 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). [54], Like other crocodilians, alligators have an armor of bony scutes. American alligators are apex predators and consume fish, amphibians, reptiles, birds, and mammals. 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. [53] There is also fluctuation in the level of bacterial taxa populations in the alligator's microbial community between seasons which helps the alligator cope with different rates of feeding and activity. [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. 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. [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. A lone American alligator was spotted for over 10 years living in a river north of Atlanta, Georgia. The two kinds of white alligators are albino and leucistic. In 1987, the USFWS removed the animal from the endangered species list, as it was considered to be fully recovered. [115] The female builds a nest of vegetation, sticks, leaves, and mud in a sheltered spot in or near the water. [48] Some American alligators are missing or have an inhibited gene for melanin, which makes them albino. [76], American alligators have been documented using lures to hunt prey such as birds. Critical to the alligator's ability to initiate a death roll, the tail must flex to a significant angle relative to its body. [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. An alligator measuring 19 ft. 2 in. [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. [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. In its plan, the state described the alligator population stretching just north of Albemarle Sound and as far west as Robeson County. Population by Place in the United States. The Chinese alligator likely descended from a lineage that crossed the Bering land bridge during the Neogene. 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. Alligators can be legally taken only . [21][22] A small population is also found in Tamaulipas, in Mexico. Some of these locations appear to be relatively recent introductions, with often small but reproductive populations. [20] The majority of American alligators inhabit Florida and Louisiana, with over a million alligators in each state. B. Young American alligators eat small fish, frogs, crayfish, and insects. Today, alligator farming is a large, growing industry in Georgia, Florida, Texas, and Louisiana. 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. 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. [58] They are found in parts of North Carolina, South Carolina, Georgia, Florida, Louisiana, Alabama, Mississippi, Arkansas, Oklahoma and Texas. Northeast Gulf Science 9: 18. This latest sighting is one of several confirmed sightings of alligators in Southwest Tennessee. The two extant species are the American alligator (A. mississippiensis) and the Chinese alligator (A. sinensis). 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. [57][58] The Aquarium of the Americas in New Orleans has leucistic alligators found in a Louisiana swamp in 1987. . [10] The largest ever recorded, found in Louisiana, measured 5.84m (19.2ft). 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. [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. Anonymous 2 y Related What is the state with the most alligators? 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. Females hatched from eggs incubated at 30C (86F) weigh significantly more than males hatched from eggs incubated at 34C (93F). This listing provides federal protection for alligators but allows state-approved management and control programs. Females generally grow to less than 9 feet and weigh up to 200 pounds. Male alligators grow faster and larger than females. [45], The alligator has a similar digestive system to that of the crocodile, with minor differences in morphology and enzyme activity. [22], In 2013, American alligators and other crocodilians were reported to also eat fruit. [35][36] Their stomachs also often contain gizzard stones. The Gatornationals is a NHRA drag race held at the Gainesville Raceway in Gainesville since 1970. 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. Keddy, P.A., L. Gough, J.A. [47] Once an alligator's meal has been processed it will move on to the second portion of the stomach which is highly acidic. The Cuban crocodile, "Trappers catch crocodile in Lake Tarpon," Tampa Bay Times, July 12, 2013. No significant difference is noted between the bite forces of male and female American alligators of equal size. 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 . The Coast Guard spotted another floating south of the Ambrose shipping . [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. 1987. It is enclosed in a pocket in the upper jaw. 1989. [47], Dorsally, adult American alligators may be olive, brown, gray, or black. (1993). 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. Oklahoma is home to between 100-200 individuals, but they constitute a stable population. [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). However, in the past few years, the population has also grown in these places. 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]. As a result, an adult human can hold an alligator's jaws shut bare-handed. [77] This means they are among the first reptiles recorded to use tools. Bellowing is performed in a "head oblique, tail arched" posture. 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. 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). This listing has been adopted by the State of Florida. 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]. Unexpected effects of predators upon their prey: The case of the American alligator. On average, it is the largest species in the family Alligatoridae, with only the black caiman being possibly longer. [99] 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. Males rarely exceed 13 feet in length and large males can weigh well over 500 pounds. [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. By the way, Florida declared the alligator their official state reptile in 1987. 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. American alligators are large crocodilians found only in the United States. These microorganisms can be found in the high surface area of the mucosa folds of the intestines, as well as throughout the digestive tract. [63], Historically, hunting and habitat loss have severely affected American alligator populations throughout their range, and whether the species would survive was in doubt. . Alligators. American alligators prevent predatory mammals from reaching island-based rookeries and in return eat spilled food and birds that fall from their nests. [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. Hatchlings mostly feed on invertebrates such as insects, insect larvae, snails, spiders, and worms, as well as small fish and frogs. Grizzly is observing in the U.S. states of Washington, Idaho, Montana, Wyoming, and Montana. Watch on. Such incidents usually involve a panther trying to cross a waterway or coming down to a swamp or river to get a drink. Louisiana has the largest alligator population. Most animals captured by American alligators are considerably smaller than itself. Adult American alligators can growl, hiss, or cough to threaten others and declare territory. On spring nights, American alligators gather in large numbers for group courtship, in the aforementioned "water dances". Unlike the other extinct alligator species of the same genus, the fossil skull was virtually indistinguishable from that of the modern American alligator. [2] Later English spellings of the name included allagarta and alagarto. [40], In summer, the female builds a nest of vegetation where the decomposition of the vegetation provides the heat needed to incubate the eggs. 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 . . [108] The American alligator can perform specific vocalizations to declare territory, signal distress, threaten competitors, and locate suitable mates. [3], They inhabit swamps, streams, rivers, ponds, and lakes. In the future, possible American alligator populations may be found in areas of Mexico adjacent to the Texas border. Adults range in color from black or dark gray to dark olive. [59] Louisiana has the largest American alligator population of any U.S. state. They are grouped in the family Alligatoridae with the caimans. 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. [110] Males are known to use infrasound during mating bellows.
