Sounds ranged from 50 to 1200Hz. Usually, terrestrial hunting occurs on nights with warm temperatures. 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. [25] In Arkansas, a man killed an American alligator that was 4.04m (13ft 3in) and 626kg (1,380lb). Wetland Ecology: Principles and Conservation (2nd edition). 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 type of food eaten by alligators depends upon their age and size. It has more alligators than any other state. 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. Recently a seven-foot alligator was videoed by TWRA Region 1 personnel in West Tennessee at the Wolf River WMA in Fayette County. [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. Alligator attacks often happen when . [86] In this way, the vital ecological service they provide may be important in reducing rates of coastal wetland losses in Louisiana. Therefore, the two forms of land locomotion can be termed the "low walk" and the "high walk". Critical to the alligator's ability to initiate a death roll, the tail must flex to a significant angle relative to its body. [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. 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. [53], When on land, an American alligator moves either by sprawling or walking, the latter involving the reptile lifting its belly off the ground. [17] However, the full genome, published in 2014, suggests that the alligator evolved much more slowly than mammals and birds.[18]. [73], American alligators modify wetland habitats, most dramatically in flat areas such as the Everglades, by constructing small ponds known as alligator holes. 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]. [72], American alligators primarily bask on shore, but also climb into and perch on tree limbs to bask if no shoreline is available. 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. [104], In East Texas, diets were diverse and adult American alligators took mammals, reptiles, amphibians, and invertebrates (e.g. Rootes, W. L., & Chabreck, R. H. (1993). Such incidents usually involve a panther trying to cross a waterway or coming down to a swamp or river to get a drink. When the jaws are closed, the edges of the upper jaws cover the lower teeth, which fit into the jaws' hollows. American alligators are apex predators and consume fish, amphibians, reptiles, birds, and mammals. This listing provides federal protection for alligators but allows state-approved management and control programs. [11] The Chinese alligator is smaller, rarely exceeding 2.1m (7ft) in length. Females generally grow to less than 9 feet and weigh up to 200 pounds. [70] In fact, the American alligator is found farther from the equator and is more equipped to handle cooler conditions than any other crocodilian. [23], American alligators live in freshwater environments, such as ponds, marshes, wetlands, rivers, lakes, and swamps, as well as in brackish water. [112] Large bellowing "choruses" of American alligators during the breeding season are commonly initiated by females and perpetuated by males. However, they can not walk on their hind legs. [24] As they grow and develop, the morphology of their teeth and jaws change significantly. Historically, the American Alligator was common and abundant throughout the southeastern United States. 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. Georgia The state of Georgia is no stranger to Alligators, and that is particularly true for the southeast quadrant of the state. [106] Their vocal folds consists of epithelium, lamina propria and muscle. Protection under the Endangered Species Act allowed the species to recuperate in many areas where it had been depleted. Keddy, P.A., L. Gough, J.A. The American alligator is a relatively large species of crocodilian. 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. The American alligator was first classified by French zoologist Franois Marie Daudin as Crocodilus mississipiensis in 1801. 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). 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. The conservation status of the American alligator is listed as Least Concern by the International Union for Conservation of Nature. American Alligator (Alligator mississippiensis) An ESA success story Photo: Expert Help. Biologists recently estimated that the state has between 32,000 and 38,000 alligators, far fewer than either Florida or Louisiana. They cause serious damage to coastal marshes and may dig burrows in levees. 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. 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] The mother defends the nest from predators and assists the hatchlings to water. [132] According to the Florida Department of Agriculture and Consumer Services, raw alligator meat contains roughly 200 Calories (840 kJ) per 3-oz (85-g) portion, of which 27 Calories (130 kJ) come from fat. Alligators in the wild can live up to 70 years; some in captivity may live even longer. The baby alligator's egg tooth helps it get out of its egg during hatching time. 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. 7 min read. The muscles that close the jaws are powerful, but the muscles for opening their jaws are weak. Louisiana What States have alligators? 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 These alligators are practically impossible to find in the wild. Most American alligators eat a wide variety of animals, including invertebrates, fish, birds, turtles, snakes, amphibians, and mammals. In some cases, larger alligators are known to ambush dogs, Florida panthers and black bears, making them the apex predator throughout their distribution. The states with the most alligators are Louisiana, Florida, and Alabama. As the frequency increases, there's high tension and large strains. Large alligators feed extensively on coypu, and provide a vital ecological service by reducing coypu numbers.[27]. Florida . 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. [44] Most other amniotes are believed to exhibit bidirectional, or tidal breathing. [65] Females and juveniles are also found in Carolina Bays and other seasonal wetlands. 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. American alligators are large crocodilians found only in the United States. In this role as a top predator, it may determine the abundance of prey species, including turtles and coypu. The 11 feet-long gator was later captured and killed. snails) in often equal measure as they did fish. In 1807, Georges Cuvier created the genus Alligator;[13] the American alligator and the Chinese alligator are the only extant species in the genus. Males rarely exceed 13 feet in length and large males can weigh well over 500 pounds. No significant difference is noted between the bite forces of male and female American alligators of equal size. "Alligator hunters, pelt traders, and runaway consumption of Gulf coast marshes: a trophic cascade perspective on coastal wetland losses". She will provide protection to the young for about a year if they remain in the area. [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. 1998. [94] 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. Gabrey, S. W. 2005. ", "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. The breeding season begins in the spring. Juveniles also make a distress call to alert their mothers if they are being threatened. and early 1960's, but protective action by state and federal governments helped keep them from disappearing completely. 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]. Nests constructed on leaves are hotter than those constructed on wet marsh, so the former tend to produce males and the latter, females. 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. [108] The American alligator can perform specific vocalizations to declare territory, signal distress, threaten competitors, and locate suitable mates. [58], Alligators are raised commercially for their meat and their skin, which when tanned is used for the manufacture of luggage, handbags, shoes, belts, and other leather items. American alligators occasionally prey on large mammals, such as deer, but usually do so when fish and smaller prey levels go down. They were removed from "total protection" status in 1987. Unexpected effects of predators upon their prey: The case of the American alligator. [1], The name "alligator" is probably an anglicized form of el lagarto, the Spanish term for "the lizard", which early Spanish explorers and settlers in Florida called the alligator. Legal Status. Oklahoma (100-200) There is a tiny population of alligators that live in certain southern regions of the state. 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. The high walk is an up-on-four-limbs forward motion used for overland travel with the belly well up from the ground. This page was last edited on 1 March 2023, at 04:33. Whenever an American alligator's mouth is closed, the fourth tooth is no longer visible. [22][23], During the 19th and 20th centuries, larger males reaching 5 to 6m (16ft 5in to 19ft 8in) were reported. Although no valid records exist about its date of birth, as of 2012, it was in its 80s and possibly the oldest alligator living in captivity. [122] American alligators are highly sensitive to changes in the hydrology, salinity, and productivity of their ecosystems; all are factors that are expected to change with Everglades restoration. They will even consume carrion if they are sufficiently hungry. In Florida, feeding wild alligators at any time is illegal. [116] The nests built on levees are warmer, thus produce males, while the cooler nests of wet marsh produce females. 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. [47] Once an alligator's meal has been processed it will move on to the second portion of the stomach which is highly acidic. Louisiana harvested about 30,000 alligators last year--a number almost equivalent to the entire Mississippi alligator population. Large male alligators are solitary territorial animals. The victim's neighbor can be heard on a 911 call as Gloria Serge was dragged underwater. 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. There are 29,322 places in the United States. [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. Alligator in captivity The states that have alligators are Florida, Mississippi, Texas, Louisiana, Alabama, North and South Carolina, and Georgia. [1] The alligator's full mitochondrial genome was sequenced in the 1990s. [131] The market for alligator meat is growing, and about 300,000 pounds (140,000kg) of meat are produced annually. Large groups of animals bellow together for a few minutes a few times a day, usually one to three hours after sunrise. [15] In 2016, a Miocene (about 23 to 5.3 Mya) fossil skull of an alligator was found at Marion County, Florida. [41] In Lake Griffin State Park, Florida, adults weighed on average 57.9kg (128lb). Coyotes Native to the western 2/3 of the U.S., coyotes began considerably extending their range in the early twentieth century. By balancing sticks and branches on their heads, American alligators are able to lure birds looking for suitable nesting material to kill and consume. Anonymous 2 y Related What is the state with the most alligators? Impacts of the coypu removal program on the diet of American alligators (. Louisiana has the largest alligator population. Such behavior has been witnessed, as well as documented from stomach contents, with the American alligators eating such fruit as wild grapes, elderberries, and citrus fruits directly from the trees. Northeast Gulf Science 9: 18. The role of the alligator in shaping plant communities and maintaining wildlife in the southern Everglades. [80][81], American alligators are considered an apex predator throughout their range. [127] Only nine fatal attacks occurred in the United States throughout the 1970s1990s, but American alligators killed 12 people between 2001 and 2007. Alligators are naturally expanding their range into Tennessee from the southern border states. Alligators first appeared during the Oligocene epoch about 37million years ago.

The folds result in greater surface area for the nutrients to be absorbed through. Alligators and caimans split in North America during the late Cretaceous, and the caimans reached South America by the Paleogene, before the closure of the Isthmus of Panama during the Neogene period, from about 23 to 2.58 Mya. Fossils identical to the existing American alligator are found throughout the Pleistocene, from 2.5 million to 11.7 thousand years ago. [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. The state that is probably least known for alligator populations is Oklahoma. The animal's dark skin is armored with small, bony scales called scutes. [82][83] As they grow, American alligators gradually expand to larger prey. Southern Florida is the only place where both alligators and crocodiles live side by side. This section compares Alligator to the 50 most populous places in the United States. While there are rules of thumb for distinguishing alligators from crocodiles, all of them admit exceptions. 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. The acidity of the stomach has been observed to increase once digestion begins. [59] Louisiana has the largest American alligator population of any U.S. state. [45], The alligator has a similar digestive system to that of the crocodile, with minor differences in morphology and enzyme activity. [88], Other animals may occasionally be eaten, even large deer or feral wild boars, but these are not normally part of the diet. Population by Place in the United States. Alligators. By 1960, however, alligators had been completely eliminated from much of their former range. A lone American alligator was spotted for over 10 years living in a river north of Atlanta, Georgia. The Coast Guard spotted another floating south of the Ambrose shipping . [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). [20] The majority of American alligators inhabit Florida and Louisiana, with over a million alligators in each state. [68][69], American alligators are less vulnerable to cold than American crocodiles. [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. 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. (2003). [50] These morphological changes correspond to shifts in the American alligators' diets, from smaller prey items such as fish and insects to larger prey items such as turtles, birds, and other large vertebrates. 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 . This marks the seventh consecutive year of growth in the wild population. 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 . Subsequent conservation efforts have allowed their numbers to increase and the species was removed from endangered status in 1987. However, in the past few years, the population has also grown in these places. [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. American alligators have 74-80 teeth. The researchers concluded that the gators, which are at the northern end of their range in this state, could be vulnerable to hunting. The gastroliths work to grind up the meal as alligators will take large bites or swallow smaller prey whole. [26] The largest American alligator ever killed in Florida was 5.31m (17ft 5in), as reported by the Everglades National Park, although this record is unverified. Alligator feeding habits: New data and a review. 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. [47], Dorsally, adult American alligators may be olive, brown, gray, or black. 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. The American alligator is the official state reptile of Florida,[133] Louisiana,[134] and Mississippi. This may encourage people to approach alligators and their nests, which can provoke the animals into attacking. Louisiana has the largest alligator population. The A. mississippiensis in Boulder, Colorado, was collected (Livo et al., 1998). Once an American alligator reaches full size and power in adulthood, any animal living in the water or coming to the water to drink is potential prey. [23] 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. [99] [64], Both the United States Fish and Wildlife Service (USFWS) and state wildlife agencies in the South contributed to the American alligator's recovery.

Oklahoma is home to between 100-200 individuals, but they constitute a stable population. [21][22] A small population is also found in Tamaulipas, in Mexico. [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. [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. Keddy PA, Gough L, Nyman JA, McFalls T, Carter J, Siegnist J (2009). [46] Alligators have a two-part stomach, with the first smaller portion containing gastroliths. Fish and Wildlife Service pronounced the American alligator fully recovered. The American alligator is capable of biting through a turtle's shell or a moderately sized mammal bone. Keddy, P.A. [6] The full genome, published in 2014, suggests that the alligator evolved much more slowly than mammals and birds. Alabama is in the outlying part of the American Alligator's range, so the population boom was a bit slower there. Herpetologica, 99-107. Hatchlings feed mostly on invertebrates. Louisiana has the highest population of alligators in the United States, and it is least surprising that the largest alligator ever recorded was also found in this state. Additionally, several extinct species of alligator are known from fossil remains. 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. 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. . [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. [74] In the limestone depressions of cypress swamps, alligator holes tend to be large and deep, while those in marl prairies and rocky glades are usually small and shallow, and those in peat depressions of ridge and slough wetlands are more variable. [123] They may provide a protection service for water birds nesting on islands in freshwater wetlands. 1989. The sprawling of American alligators and other crocodylians is not similar to that of salamanders and lizards, being similar to walking. 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]. Louisiana has the highest alligator population, currently approaching 2 million. Sharks are also known to prey on American alligators, in turn, indicating that encounters between the two predators are common. [24] Mother American alligators eventually become more aggressive towards their young, which encourages them to disperse. The Chinese alligator likely descended from a lineage that crossed the Bering land bridge during the Neogene. [24] American alligators are often mistaken for a similar animal: the American crocodile. As the alveoli represent dead-ends to flow, the inspired air must move back out the same way it came in. In places like South Carolina, the alligator population is now estimated to be as much as 16 times higher than in the mid-1970s. [95] American alligator predation on American black bears has also been recorded. 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. On average, it is the largest species in the family Alligatoridae, with only the black caiman being possibly longer. Most of the state gets much too cold for gators to survive the winter, but there are some small regions that allow for a small population. Alligators generally mature at a length of 1.8m (6ft). 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). Mistaken identity leading to an attack is always possible, especially in or near cloudy waters. Adult alligators regularly cannibalize younger individuals, though estimates of the rate of cannibalism vary widely. In 1987, the USFWS removed the animal from the endangered species list, as it was considered to be fully recovered. Like the spectacled caiman, this species has a bony nasal ridge, though it is less prominent. Fully recovered state Park, Florida, and runaway consumption of Gulf marshes.
