alligator population by state

[117] The female remains near the nest throughout the 65-day incubation period, protecting it from intruders. American alligators are apex predators and consume fish, amphibians, reptiles, birds, and mammals. The state that is probably least known for alligator populations is Oklahoma. Incubation temperatures of 30C (86F) or lower produce a clutch of females; those of 34C (93F) or higher produce entirely males. 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. Alligators. 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. Northeast Gulf Science 9: 18. Females generally grow to less than 9 feet and weigh up to 200 pounds. The acidity of the stomach has been observed to increase once digestion begins. Alligators. 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. [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. In one experiment conducted on the larynx, the fundamental frequency depended on both the glottal gap and stiffness of the larynx tissues. Adult alligators regularly cannibalize younger individuals, though estimates of the rate of cannibalism vary widely. [20] The majority of American alligators inhabit Florida and Louisiana, with over a million alligators in each state. The Chinese alligator likely descended from a lineage that crossed the Bering land bridge during the Neogene. [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. 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. [11] Male American alligators use infrasound to attract females. The largest of the species (both males and females) defend prime territory; smaller alligators have a higher tolerance for other alligators within a similar size class. It is common to use several wraps of duct tape to prevent an adult alligator from opening its jaws when being handled or transported. Young American alligators eat small fish, frogs, crayfish, and insects. [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. [76], American alligators have been documented using lures to hunt prey such as birds. The Cuban crocodile, "Trappers catch crocodile in Lake Tarpon," Tampa Bay Times, July 12, 2013. 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. The state has one million wild alligators and another million on alligator farms. 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. 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. 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. The ontogeny of bite-force performance in American alligator (Alligator mississippiensis). While there are rules of thumb for distinguishing alligators from crocodiles, all of them admit exceptions. [65] Females and juveniles are also found in Carolina Bays and other seasonal wetlands. [52], During brumation the process of digestion experiences changes due to the fasting most alligators experience during these periods of inactivity. As the frequency increases, there's high tension and large strains. The mating season is in late spring. Some of these locations appear to be relatively recent introductions, with often small but reproductive populations. [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. In its plan, the state described the alligator population stretching just north of Albemarle Sound and as far west as Robeson County. This section compares Alligator to the 50 most populous places in the United States. Such incidents usually involve a panther trying to cross a waterway or coming down to a swamp or river to get a drink. [110] Males are known to use infrasound during mating bellows.

[16][17], Alligators are native to only the United States, Mexico, and China. If fed, the alligators will eventually lose their fear of humans and will learn to associate humans with food.[34]. [25] They are, therefore, considered an important species for maintaining ecological diversity in wetlands. [94] Females hatched from eggs incubated at 30C (86F) weigh significantly more than males hatched from eggs incubated at 34C (93F). [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. Fossils identical to the existing American alligator are found throughout the Pleistocene, from 2.5 million to 11.7 thousand years ago. Population by Place in the United States. As they mature, progressively larger prey is taken, including larger fish such as gar, turtles, and various mammals, particularly coypu and muskrat,[24] as well as birds, deer, and other reptiles. The animal's dark skin is armored with small, bony scales called scutes. Estimated to be between 426.72cm and 457.2cm when spotted. )", "Crocodilian Species - American Alligator (Alligator mississippiensis)". may seem too good to be true, but then, some truths are quite incredible in themselves. [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. [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. 10. (2016, April 30). [75], The teeth of the American alligator are designed to grip prey, but cannot rip or chew flesh like teeth of some other predators (such as canids and felids), and depend on their gizzard, instead, to masticate their food. Ecosystems 2: 4963. [11] The Chinese alligator is smaller, rarely exceeding 2.1m (7ft) in length. 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. Louisiana harvested about 30,000 alligators last year--a number almost equivalent to the entire Mississippi alligator population. Cannibalism in the American alligator. Black caiman, Charles, S.; Ross, A. and Garnett, Stephen (1989), Erickson, G. M., Lappin, A. K., & Vliet, K. A. 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. [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 muscles that close the jaws are powerful, but the muscles for opening their jaws are weak. Bellowing is performed in a "head oblique, tail arched" posture. Alligators are naturally expanding their range into Tennessee from the southern border states. The alligator has recovered from extremely low population levels in the mid-1900s and is now recreationally and commercially hunted in many southeastern states. 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. These microorganisms can be found in the high surface area of the mucosa folds of the intestines, as well as throughout the digestive tract. The American alligator is a stunning example of a species that has fully recovered in large part due to protections provided by the Endangered Species Act. Rootes, W. L., & Chabreck, R. H. (1993). 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. [66], Nutria were introduced into coastal marshes from South America in the mid-20th century, and their population has since exploded into the millions. [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. In this role as a top predator, it may determine the abundance of prey species, including turtles and coypu. 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). [118] Young alligators grow 38in (7.620.3cm) a year and reach adulthood at 6ft (1.8m). [116] The nests built on levees are warmer, thus produce males, while the cooler nests of wet marsh produce females. [32], Most of the muscle in an alligator's jaw evolved to bite and grip prey. Louisiana and Florida. Wetland Ecology: Principles and Conservation (2nd edition). The air first enters the outer branch, moves through the parabronchi, and exits the lung through the inner branch. Juveniles also make a distress call to alert their mothers if they are being threatened. Fish and Wildlife Service pronounced the American alligator fully recovered. [24] Hatchlings gather into pods and are guarded by their mother and keep in contact with her through their "yelping" vocalizations. [63], Historically, hunting and habitat loss have severely affected American alligator populations throughout their range, and whether the species would survive was in doubt. Some 23 dead whales have washed ashore along the East Coast since early December, including 12 in New Jersey and New York. This listing has been adopted by the State of Florida. [50] American alligators have broad snouts, especially in captive individuals. Whenever an American alligator's mouth is closed, the fourth tooth is no longer visible. 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. Together, these two subfamilies form the family Alligatoridae. [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. 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. [37][27] As humans encroach into their habitat, attacks are few but not unknown. [54], Like other crocodilians, alligators have an armor of bony scutes. [84] Stomach contents show, among native mammals, muskrats and raccoons are some of the most commonly eaten species. [121], American alligators play an important role in the restoration of the Everglades as biological indicators of restoration success. [7], The genus Alligator belongs to the subfamily Alligatorinae, which is the sister taxon to Caimaninae (the caimans). Large male alligators are solitary territorial animals. [57][58] The Aquarium of the Americas in New Orleans has leucistic alligators found in a Louisiana swamp in 1987. [77] This means they are among the first reptiles recorded to use tools.

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. [59] Louisiana has the largest American alligator population of any U.S. state. Males rarely exceed 13 feet in length and large males can weigh well over 500 pounds. [86] In this way, the vital ecological service they provide may be important in reducing rates of coastal wetland losses in Louisiana. [50] Another study noted that as the American alligator increases in size, the force of its bite also increases. Indeed, far more Chinese alligators live in zoos around the world than can be found in the wild. They cause serious damage to coastal marshes and may dig burrows in levees. Louisiana What States have alligators? In NC, males can reach 13 feet and weigh up to 500 pounds or more. The American alligator was first classified by French zoologist Franois Marie Daudin as Crocodilus mississipiensis in 1801. The folds result in greater surface area for the nutrients to be absorbed through. Alligators also provide economic benefits through the ecotourism industry. The natural sex ratio at hatching is five females to one male. [22][23], During the 19th and 20th centuries, larger males reaching 5 to 6m (16ft 5in to 19ft 8in) were reported. 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. [22], In 2013, American alligators and other crocodilians were reported to also eat fruit. [44], While noticeable in very mature specimens, the sexual dimorphism in size of the American alligator is relatively modest among crocodilians.

[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. 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? 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. [123] They may provide a protection service for water birds nesting on islands in freshwater wetlands. Therefore, the two forms of land locomotion can be termed the "low walk" and the "high walk". Additionally, it weighs considerably less, with males rarely over 45kg (100lb). Herp highlight #1: American alligator. The construction of nests along the periphery of alligator holes, as well as a buildup of soils during the excavation process, provides drier areas for other reptiles to nest and a place for plants that are intolerant of inundation to colonize. 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. [105], An American alligator is able to abduct and adduct the vocal folds of its larynx, but not to elongate or shorten them; yet in spite of this, it can modulate fundamental frequency very well. [10] The largest ever recorded, found in Louisiana, measured 5.84m (19.2ft). 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. Alligators generally mature at a length of 1.8m (6ft). [3], Alligators and caimans split in North America during the early Tertiary or late Cretaceous (about 53 million to about 65 million years ago). Most animals captured by American alligators are considerably smaller than itself. In 1987, the USFWS removed the animal from the endangered species list, as it was considered to be fully recovered. Alligators in the wild can live up to 70 years; some in captivity may live even longer. Rockefeller Wildlife Refuge in southern Louisiana has several in captivity in an attempt to preserve the species. Its front feet have 5 toes, while rear feet have 4 toes that are webbed. 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 high walk is an up-on-four-limbs forward motion used for overland travel with the belly well up from the ground. [24] Other prey, including snakes, lizards, and various invertebrates, are eaten occasionally by adults. Members of this superfamily first arose in the late Cretaceous, about 10065 million years ago (Mya). [20] The majority of American alligators inhabit Florida and Louisiana, with over a million alligators in each state. 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. Both sexes may den underneath banks or clumps of trees during the winter. Here's a complete rundown. [26] Farther west, in Louisiana, heavy grazing by coypu and muskrat are causing severe damage to coastal wetlands. [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. Keddy, P.A., L. Gough, J.A. Alligator in captivity The states that have alligators are Florida, Mississippi, Texas, Louisiana, Alabama, North and South Carolina, and Georgia. [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. Leidyosuchus of Alberta is the earliest known fossil, from the Campanian era 83 to 72 Mya. [5][6] On rare occasions, a large, old male may grow to an even greater length. Nyman, T. McFalls, J. Carter and J. Siegrist (2009). Alabama is in the outlying part of the American Alligator's range, so the population boom was a bit slower there. The victim's neighbor can be heard on a 911 call as Gloria Serge was dragged underwater. Alligator hunters, pelt traders, and runaway consumption of Gulf coast marshes: A trophic cascade perspective on coastal wetland losses. "Gators" has been the nickname of the University of Florida's sports teams since 1911. [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. [25] In Arkansas, a man killed an American alligator that was 4.04m (13ft 3in) and 626kg (1,380lb). 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. [80][81], American alligators are considered an apex predator throughout their range. In April and May, alligators form so-called "bellowing choruses". The type of food eaten by alligators depends upon their age and size. Male alligators grow faster and larger than females. Baton Rouge: Louisiana State University Press. [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. Almost black in color, the it has prominent eyes and nostrils with coarse scales over the entire body. [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. However, it is listed as 'threatened by similarity of appearance', and as such, harvest and management is governed by the CITES Treaty (Convention . 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). This differs from Nile crocodiles, which lay their eggs in pits. 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". 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. 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). Fish and Wildlife, both Florida and Louisiana have 1.5 million alligators. Historically, hunting had decimated their population, and the American alligator was listed as an endangered species by the Endangered Species Act of 1973. 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). [48] The re-circulation of blood leads to higher CO2 concentration as well as lower oxygen affinity. [44] Most other amniotes are believed to exhibit bidirectional, or tidal breathing. Throughout the year (in particular during the breeding season), American alligators bellow to declare territory, and locate suitable mates. Louisiana has the highest alligator population, approaching 2 million (alligatorfur.com) According to U.S. 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]. Smaller alligators can often be found in large numbers close to each other. [127] Only nine fatal attacks occurred in the United States throughout the 1970s1990s, but American alligators killed 12 people between 2001 and 2007. This may encourage people to approach alligators and their nests, which can provoke the animals into attacking. Wiki User . This listing provides federal protection for alligators but allows state-approved management and control programs. Wild Alligator Harvest Summaries By Year 2021 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 In Louisiana, alligators are most common in coastal marshes. Herpetologica, 99-107. [51] Alligators also have highly folded mucosa in the lining of the intestines to further aid in the absorption of nutrients. Unusually in these regions, reptiles and amphibians were the most important nonpiscivore prey, mostly turtles and water snakes. By the way, Florida declared the alligator their official state reptile in 1987.
