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. Wild Alligator Harvest Summaries By Year 2021 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 It has more alligators than any other state. [113] Observers of large bellowing choruses have noted they are often felt more than they are heard due to the intense infrasound emitted by males. Adults range in color from black or dark gray to dark olive. The folds result in greater surface area for the nutrients to be absorbed through. Alligator feeding habits: New data and a review. [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. Alligator in captivity The states that have alligators are Florida, Mississippi, Texas, Louisiana, Alabama, North and South Carolina, and Georgia. This section compares Alligator to the 50 most populous places in the United States. [17] However, the full genome, published in 2014, suggests that the alligator evolved much more slowly than mammals and birds.[18]. Legal Status. 497 p. Chapter 4. Cambridge University Press, Cambridge, UK. 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. [76], American alligators have been documented using lures to hunt prey such as birds. The species is the official state reptile of three states: Florida, Louisiana, and Mississippi. [50] Juveniles have small, needle-like teeth that become much more robust and narrow snouts that become broader as the individuals develop. (2010). The state has one million wild alligators and another million on alligator farms. 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. 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. -23.28% (-27) Rank in State 354th Rank in Country 26937th The current population of Alligator, Mississippi is 89 based on our projections of the latest US Census estimates.The last official US Census in 2020 recorded the population at 116. [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. [68][69], American alligators are less vulnerable to cold than American crocodiles. 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. Gabrey, S. W. 2005. [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). They are grouped in the family Alligatoridae with the caimans. Smaller alligators can often be found in large numbers close to each other. [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. They were removed from "total protection" status in 1987. This process makes digestion and nutrient absorption easier once the food reaches the second portion of the stomach. Alligator hides bring good prices and hides in the 6- to 7-ft range have sold for $300 each. Sounds ranged from 50 to 1200Hz. The air first enters the outer branch, moves through the parabronchi, and exits the lung through the inner branch. 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. Rockefeller Wildlife Refuge in southern Louisiana has several in captivity in an attempt to preserve the species. [29], American alligators do not normally reach such extreme sizes. The wild population of Mexican wolves in the United States continued to grow in 2022. 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. 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 . Killed by Max Touchet, a game warden on Marsh Island following an attempted live capture. Population by Place in the United States. 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. 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. [29][30][31], Although the alligator has a heavy body and a slow metabolism, it is capable of short bursts of speed, especially in very short lunges. [23][125] Alligator bites are serious injuries, due to the reptile's sheer bite force and risk of infection. [24] When they construct alligator holes in the wetlands, they increase plant diversity and provide habitat for other animals during droughts. [110] Males are known to use infrasound during mating bellows. They may kill larger prey by grabbing it and dragging it into the water to drown. Louisiana harvested about 30,000 alligators last year--a number almost equivalent to the entire Mississippi alligator population. On spring nights, American alligators gather in large numbers for group courtship, in the aforementioned "water dances". [21][22] A small population is also found in Tamaulipas, in Mexico. [52], Alligators also have complex microbiomes that are not fully understood yet, but can be attributed to both benefits and costs to the animal. [86][85] It has also been reported that large American alligators prey on medium-sized American alligators, which had preyed on hatchlings and smaller juveniles. [93] However, the python is also known to occasionally prey on alligators, a form of both competition and predation. [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. Oklahoma (100-200) There is a tiny population of alligators that live in certain southern regions of the state. [45], The alligator has a similar digestive system to that of the crocodile, with minor differences in morphology and enzyme activity. The Chinese alligator likely descended from a lineage that crossed the Bering land bridge during the Neogene. [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. These microorganisms can be found in the high surface area of the mucosa folds of the intestines, as well as throughout the digestive tract. It has a large, long head with visible upper teeth along the edge of the jaws. However, they can not walk on their hind legs. [137] Allegheny College and San Francisco State University both have Gators as their mascots, as well.[138]. [86], Recently, a population of Burmese pythons became established in Everglades National Park. Florida . 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. Alligators have muscular, flat tails that propel them while swimming. [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. Rootes, W. L., & Chabreck, R. H. (1993). Keddy, P.A. [112] Large bellowing "choruses" of American alligators during the breeding season are commonly initiated by females and perpetuated by males. Protection under the Endangered Species Act allowed the species to recuperate in many areas where it had been depleted. In its plan, the state described the alligator population stretching just north of Albemarle Sound and as far west as Robeson County. 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). 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. [64], Both the United States Fish and Wildlife Service (USFWS) and state wildlife agencies in the South contributed to the American alligator's recovery. American alligators have 74-80 teeth. Southern Florida is the only place where both alligators and crocodiles live side by side. The alligator now has a status of "threatened due to 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. [66], Nutria were introduced into coastal marshes from South America in the mid-20th century, and their population has since exploded into the millions. The two states that have the most gators are Florida and Louisiana. 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. [16][17], Alligators are native to only the United States, Mexico, and China. [114], American alligators typically live to the age of 50, and possibly over 70 years old. [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. 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. In 1807, Georges Cuvier created the genus Alligator;[13] the American alligator and the Chinese alligator are the only extant species in the genus. [73], American alligators modify wetland habitats, most dramatically in flat areas such as the Everglades, by constructing small ponds known as alligator holes. Alligators generally mature at a length of 1.8m (6ft). When young, alligators eat fish, insects, snails, crustaceans, and worms. [2] Later English spellings of the name included allagarta and alagarto. The below cladogram shows the phylogeny of alligators. Since 1948, 257 documented attacks on humans in Florida (about five incidents per year) have been reported, of which an estimated 23 resulted in death. Alabama is in the outlying part of the American Alligator's range, so the population boom was a bit slower there. Keddy, P.A., L. Gough, J.A. Retrieved April 08, 2021, from, Thorbjarnarson, J. [118] They are preyed on by large fish, birds, raccoons, Florida panthers, and adult American alligators. [39] In 2010, on spring nights alligators were found to gather in large numbers for group courtship, the so-called "alligator dances". [117] The female remains near the nest throughout the 65-day incubation period, protecting it from intruders. 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.

The Coast Guard spotted another floating south of the Ambrose shipping . [100] Additionally, American alligators engage in what seems to be cooperative hunting. 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). Fossils identical to the existing American alligator are found throughout the Pleistocene, from 2.5 million to 11.7 thousand years ago. [54] In the water, American alligators swim like fish, moving their pelvic regions and tails from side to side.
