[70] In fact, the American alligator is found farther from the equator and is more equipped to handle cooler conditions than any other crocodilian. [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. [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 discovery of this unexpected part of the American alligator diet further reveals that they may be responsible for spreading seeds from the fruit they consume across their habitat. Domestic American alligators range from long and slender to short and robust, possibly in response to variations in factors such as growth rate, diet, and climate. The Coast Guard spotted another floating south of the Ambrose shipping . 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. "Alligator hunters, pelt traders, and runaway consumption of Gulf coast marshes: a trophic cascade perspective on coastal wetland losses". [15] In 2016, a Miocene (about 23 to 5.3 Mya) fossil skull of an alligator was found at Marion County, Florida. 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. The American alligator is a relatively large species of crocodilian. [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. 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. 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 . [24] Other prey, including snakes, lizards, and various invertebrates, are eaten occasionally by adults.

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. They may kill larger prey by grabbing it and dragging it into the water to drown. Unusually in these regions, reptiles and amphibians were the most important nonpiscivore prey, mostly turtles and water snakes. They are grouped in the family Alligatoridae with the caimans. 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. Its front feet have 5 toes, while rear feet have 4 toes that are webbed. Additionally, it weighs considerably less, with males rarely over 45kg (100lb). [22], In 2013, American alligators and other crocodilians were reported to also eat fruit. The Gatornationals is a NHRA drag race held at the Gainesville Raceway in Gainesville since 1970. This listing has been adopted by the State of Florida. In Florida, feeding wild alligators at any time is illegal. Male alligators grow faster and larger than females. 9 p.

Louisiana has the largest alligator population. B. However, they can not walk on their hind legs. [96][97][98], Occasionally, domestic animals, including dogs, cats, and calves, are taken as available, but are secondary to wild and feral prey. These items help the American alligator in the process of digestion by crushing up the meat and bones of animals, especially animals with shells. [93] However, the python is also known to occasionally prey on alligators, a form of both competition and predation. The agency annually issues about 2,500 tags, with most of those tags used . 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. Nyman, T. McFalls, J. Carter and J. Siegrist (2009). The state has a "healthy and stable population" of about 1.3 million alligators of every size, but the most common range in size from 4-12 feet. [35][36] Their stomachs also often contain gizzard stones. [70] This adaptiveness is thought to be why American alligators are widespread further north than the American crocodile. 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. Oxygen exchange takes place in extensive vasculature around the parabronchi.

This behavior has qualified the American alligator to be considered a keystone species. 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. This is due to the increase in CO2 concentration of the blood, resulting from the right to left shunting of the alligators heart. Impacts of the coypu removal program on the diet of American alligators (. [54], Like other crocodilians, alligators have an armor of bony scutes. 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. Fossils identical to the existing American alligator are found throughout the Pleistocene, from 2.5 million to 11.7 thousand years ago. Ecosystems 2: 4963. may seem too good to be true, but then, some truths are quite incredible in themselves. [57], American alligators, being native both to the Nearctic and Neotropical realms, are found in the wild in the Southeastern United States, from the Lowcountry in South Carolina, south to Everglades National Park in Florida, and west to the southeastern region of Texas. 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. This differs from Nile crocodiles, which lay their eggs in pits. 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. [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. 115133. [48] The re-circulation of blood leads to higher CO2 concentration as well as lower oxygen affinity. The sprawling of American alligators and other crocodylians is not similar to that of salamanders and lizards, being similar to walking. The 11 feet-long gator was later captured and killed. [10] The largest ever recorded, found in Louisiana, measured 5.84m (19.2ft). The Gator Bowl is a college football game held in Jacksonville annually since 1946, with Gator Bowl Stadium hosting the event until the 1993 edition. The young are tiny replicas of adults, with a series of yellow bands around their bodies that serve as camouflage. This information helps TPWD determine trends in the population, assess alligator habitat and establish wise hunting limits for the species. Therefore, the two forms of land locomotion can be termed the "low walk" and the "high walk". In the future, possible American alligator populations may be found in areas of Mexico adjacent to the Texas border. [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. The American alligator is a large, semi-aquatic, armored reptile that is related to crocodiles. While events of predation by Burmese pythons on any sizable American alligators have been observed,[94][119][120] no evidence of a net negative effect has been seen on overall American alligator populations. Protection under the Endangered Species Act allowed the species to recuperate in many areas where it had been depleted. 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. The Florida Naturalist, 41, 27, 6974. The Amphibians and Reptiles of Louisiana. [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. Large American alligators feed heavily on nutria, so American alligators may not only control nutria populations in Louisiana, but also prevent them spreading east into the Everglades. [37][27] As humans encroach into their habitat, attacks are few but not unknown. [17] However, the full genome, published in 2014, suggests that the alligator evolved much more slowly than mammals and birds.[18]. [24] Mother American alligators eventually become more aggressive towards their young, which encourages them to disperse. Rootes, W. L., & Chabreck, R. H. (1993). As a result, an adult human can hold an alligator's jaws shut bare-handed. [44], While noticeable in very mature specimens, the sexual dimorphism in size of the American alligator is relatively modest among crocodilians. Herp highlight #1: American alligator. View Case History American Alligator(1).pdf from FW 350 at Oregon State University, Corvallis. [104], In East Texas, diets were diverse and adult American alligators took mammals, reptiles, amphibians, and invertebrates (e.g. Alligators. Indeed, far more Chinese alligators live in zoos around the world than can be found in the wild. Journal of Zoology, 260(3), 317-327. 7 min read. [23][125] Alligator bites are serious injuries, due to the reptile's sheer bite force and risk of infection. "Gators" has been the nickname of the University of Florida's sports teams since 1911. [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. Like many reptiles, alligators reach a larger size in Florida and other southern latitudes, sometimes reaching 15 feet. [118] They are preyed on by large fish, birds, raccoons, Florida panthers, and adult American alligators. [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. [21] [22] A small population is also found in Tamaulipas, in Mexico. [47] Once an alligator's meal has been processed it will move on to the second portion of the stomach which is highly acidic. Adults range in color from black or dark gray to dark olive. The American alligator was abundant in the pre-drainage Everglades in south Florida. 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. The American alligator was first classified by French zoologist Franois Marie Daudin as Crocodilus mississipiensis in 1801. Hatchlings mostly feed on invertebrates such as insects, insect larvae, snails, spiders, and worms, as well as small fish and frogs. The modern American alligator is well represented in the fossil record of the Pleistocene. Nests constructed on leaves are hotter than those constructed on wet marsh, so the former tend to produce males and the latter, females. 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. Smaller alligators can often be found in large numbers close to each other. Georgia The state of Georgia is no stranger to Alligators, and that is particularly true for the southeast quadrant of the state. The alligator is no longer endangered. They were removed from "total protection" status in 1987. A lone American alligator was spotted for over 10 years living in a river north of Atlanta, Georgia. This process makes digestion and nutrient absorption easier once the food reaches the second portion of the stomach. 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. [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. Additionally, several extinct species of alligator are known from fossil remains. [26] Farther west, in Louisiana, heavy grazing by coypu and muskrat are causing severe damage to coastal wetlands. Alligators first appeared during the Oligocene epoch about 37million years ago. In its plan, the state described the alligator population stretching just north of Albemarle Sound and as far west as Robeson County. Members of this superfamily first arose in the late Cretaceous, about 10065 million years ago (Mya). Wild Alligator Harvest Summaries By Year 2021 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 In contrast, air in alligator lungs makes a circuit, moving in only one direction through the parabronchi. This latest sighting is one of several confirmed sightings of alligators in Southwest Tennessee. [110] Males are known to use infrasound during mating bellows. The American alligator is the official state reptile of Florida,[133] Louisiana,[134] and Mississippi. Cannibalism in the American alligator. Virginia Living Museum. 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. Together, these two subfamilies form the family Alligatoridae. Black caiman, Charles, S.; Ross, A. and Garnett, Stephen (1989), Erickson, G. M., Lappin, A. K., & Vliet, K. A. . 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. 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. [50] Another study noted that as the American alligator increases in size, the force of its bite also increases. Reproduction By the way, Florida declared the alligator their official state reptile in 1987. Historically, hunting had decimated their population, and the American alligator was listed as an endangered species by the Endangered Species Act of 1973. 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. [33], Alligators are generally timid towards humans and tend to walk or swim away if one approaches. Almost black in color, the it has prominent eyes and nostrils with coarse scales over the entire body. 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. [45], The alligator has a similar digestive system to that of the crocodile, with minor differences in morphology and enzyme activity. Alligators move on land by two forms of locomotion referred to as "sprawl" and "high walk". American alligators are apex predators and consume fish, amphibians, reptiles, birds, and mammals. Some of these locations appear to be relatively recent introductions, with often small but reproductive populations. [118] Young alligators grow 38in (7.620.3cm) a year and reach adulthood at 6ft (1.8m). [57][58] The Aquarium of the Americas in New Orleans has leucistic alligators found in a Louisiana swamp in 1987. Alligators have muscular, flat tails that propel them while swimming. [25] In Arkansas, a man killed an American alligator that was 4.04m (13ft 3in) and 626kg (1,380lb). ", "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. [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. 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. An alligator with an immobilized tail cannot perform a death roll. 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. 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). The two kinds of white alligators are albino and leucistic. [86] In this way, the vital ecological service they provide may be important in reducing rates of coastal wetland losses in Louisiana. 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. snails) in often equal measure as they did fish. [127] Only nine fatal attacks occurred in the United States throughout the 1970s1990s, but American alligators killed 12 people between 2001 and 2007. Leidyosuchus of Alberta is the earliest known fossil, from the Campanian era 83 to 72 Mya. American Alligator (Alligator mississippiensis) An ESA success story Photo: Expert Help. )", "Crocodilian Species - American Alligator (Alligator mississippiensis)". Alligator hides bring good prices and hides in the 6- to 7-ft range have sold for $300 each. Southern Florida is the only place where both alligators and crocodiles live side by side. Alligators. [59] Louisiana has the largest American alligator population of any U.S. state. Young are born with yellow bands around their bodies and are protected by their mother for up to one year.[12]. The A. mississippiensis in Boulder, Colorado, was collected (Livo et al., 1998). [123] They may provide a protection service for water birds nesting on islands in freshwater wetlands. (2003). 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". [40], In summer, the female builds a nest of vegetation where the decomposition of the vegetation provides the heat needed to incubate the eggs. [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. 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. Craighead, F. C., Sr. (1968). 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). 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. 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]. [137] Allegheny College and San Francisco State University both have Gators as their mascots, as well.[138]. The muscles that close the jaws are powerful, but the muscles for opening their jaws are weak. [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. [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. [99] [58] They are found in parts of North Carolina, South Carolina, Georgia, Florida, Louisiana, Alabama, Mississippi, Arkansas, Oklahoma and Texas. 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. . 1998. [22] Meanwhile, their undersides are cream-colored. The conservation status of the American alligator is listed as Least Concern by the International Union for Conservation of Nature. [52], Alligators also have complex microbiomes that are not fully understood yet, but can be attributed to both benefits and costs to the animal. Grizzly is observing in the U.S. states of Washington, Idaho, Montana, Wyoming, and Montana.

No significant difference is noted between the bite forces of male and female American alligators of equal size. [41] The mother defends the nest from predators and assists the hatchlings to water. Eggs are laid in a nest of vegetation, sticks, leaves, and mud in a sheltered spot in or near the water. [51] Alligators also have highly folded mucosa in the lining of the intestines to further aid in the absorption of nutrients. 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. [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 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. [135] Several organizations and products from Florida have been named after the animal. 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). [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. Gabrey, S. W. 2005. Both sexes may den underneath banks or clumps of trees during the winter. [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). For the history, the United States is the only nation on earth where both alligators and . [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. These microorganisms can be found in the high surface area of the mucosa folds of the intestines, as well as throughout the digestive tract. 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.
