alligator population by state

This type of protection allowed the alligator population to increase. Females are smaller, measuring 2.6 to 3m (8.5 to 9.8ft) in length. Herpetologica, 99-107. [115] The female builds a nest of vegetation, sticks, leaves, and mud in a sheltered spot in or near the water.

During summer, males still preferred open water, while females remained in the swamps to construct their nests and lay their eggs. There are 29,322 places in the United States. snails) in often equal measure as they did fish. 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. This listing provides federal protection for alligators but allows state-approved management and control programs. While there are rules of thumb for distinguishing alligators from crocodiles, all of them admit exceptions. [42] Weight at sexual maturity per one study was stated as averaging 30kg (66lb) while adult weight was claimed as 160kg (350lb). [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. Louisiana harvested about 30,000 alligators last year--a number almost equivalent to the entire Mississippi alligator population. Oklahoma (100-200) There is a tiny population of alligators that live in certain southern regions of the state. Northeast Gulf Science 9: 18. [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. Some 23 dead whales have washed ashore along the East Coast since early December, including 12 in New Jersey and New York. Alligator hides bring good prices and hides in the 6- to 7-ft range have sold for $300 each. [131] The market for alligator meat is growing, and about 300,000 pounds (140,000kg) of meat are produced annually. 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. Almost black in color, the it has prominent eyes and nostrils with coarse scales over the entire body. Louisiana and Florida. [70] This adaptiveness is thought to be why American alligators are widespread further north than the American crocodile. Adults range in color from black or dark gray to dark olive. The young are tiny replicas of adults, with a series of yellow bands around their bodies that serve as camouflage. [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. The bellows of male American alligators are accompanied by powerful blasts of infrasound. American alligator predation on Florida panthers is rare, but has been documented. On spring nights, American alligators gather in large numbers for group courtship, in the aforementioned "water dances". [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. [25] In Arkansas, a man killed an American alligator that was 4.04m (13ft 3in) and 626kg (1,380lb). Today, alligator farming is a large, growing industry in Georgia, Florida, Texas, and Louisiana. When young, alligators eat fish, insects, snails, crustaceans, and worms. Together, these two subfamilies form the family Alligatoridae. Mistaken identity leading to an attack is always possible, especially in or near cloudy waters. 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? [80][81], American alligators are considered an apex predator throughout their range. Alligator in captivity The states that have alligators are Florida, Mississippi, Texas, Louisiana, Alabama, North and South Carolina, and Georgia. [60] Alligators have been naturally expanding their range into Tennessee,[61] and have established a small population in the southwestern part of that state via inland waterways, according to the state's wildlife agency. [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. 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. 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 alligator has recovered from extremely low population levels in the mid-1900s and is now recreationally and commercially hunted in many southeastern states. Large male alligators are solitary territorial animals. [19] Weight varies considerably depending on length, age, health, season, and available food sources. Alligators. [57][58] The Aquarium of the Americas in New Orleans has leucistic alligators found in a Louisiana swamp in 1987. The least populous of the compared places has a population of 383,899. 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. [22][23], During the 19th and 20th centuries, larger males reaching 5 to 6m (16ft 5in to 19ft 8in) were reported. 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. Estimated to be between 426.72cm and 457.2cm when spotted. 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). [citation needed], Alligators, much like birds, have been shown to exhibit unidirectional movement of air through their lungs. [72], American alligators primarily bask on shore, but also climb into and perch on tree limbs to bask if no shoreline is available. Miami MetroZoo in Florida also has a breeding pair of Chinese alligators. [99] Black caiman, Charles, S.; Ross, A. and Garnett, Stephen (1989), Erickson, G. M., Lappin, A. K., & Vliet, K. A. This latest sighting is one of several confirmed sightings of alligators in Southwest Tennessee. ", "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. Cambridge University Press, Cambridge, UK. The American alligator is capable of biting through a turtle's shell or a moderately sized mammal bone. Protection under the Endangered Species Act allowed the species to recuperate in many areas where it had been depleted. In order to understand and properly manage Texas's alligator population, TPWD Wildlife Division conducts extensive studies in the state on the number, character and harvest of alligators every year. 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. "Gators" has been the nickname of the University of Florida's sports teams since 1911. Alligators are naturally expanding their range into Tennessee from the southern border states. Louisiana has the largest alligator population. 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. [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. [129] At least 28 fatal attacks by American alligators have occurred in the United States since 1970. [11] Male American alligators use infrasound to attract females. 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. However, in the past few years, the population has also grown in these places. [59] Louisiana has the largest American alligator population of any U.S. state. Impacts of the coypu removal program on the diet of American alligators (. The gastroliths work to grind up the meal as alligators will take large bites or swallow smaller prey whole. [121], American alligators play an important role in the restoration of the Everglades as biological indicators of restoration success. [94] [58] They are found in parts of North Carolina, South Carolina, Georgia, Florida, Louisiana, Alabama, Mississippi, Arkansas, Oklahoma and Texas. 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. They cause serious damage to coastal marshes and may dig burrows in levees. Here's a complete rundown. [21][22] A small population is also found in Tamaulipas, in Mexico. "Severe mammal declines coincide with proliferation of invasive Burmese pythons in Everglades National Park", "Key West Florida Attractions | Alligator Exhibit", "Crocodiles and alligators like to chomp down on fruit! 1998. Morgan, G. S., Richard, F., & Crombie, R. I. [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. While they prefer fresh water, American alligators may sometimes wander into brackish water,[66] but are less tolerant of salt water than American crocodiles, as the salt glands on their tongues do not function. [68][69], American alligators are less vulnerable to cold than American crocodiles. [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. 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. The researchers concluded that the gators, which are at the northern end of their range in this state, could be vulnerable to hunting. The mating season is in late spring. By the way, Florida declared the alligator their official state reptile in 1987. By 1960, however, alligators had been completely eliminated from much of their former range. Alligators have muscular, flat tails that propel them while swimming. In the future, possible American alligator populations may be found in areas of Mexico adjacent to the Texas border. 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. Southern Florida is the only place where both alligators and crocodiles live side by side. 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. Nyman, T. McFalls, J. Carter and J. Siegrist (2009). 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]. If fed, the alligators will eventually lose their fear of humans and will learn to associate humans with food.[34]. Keddy PA, Gough L, Nyman JA, McFalls T, Carter J, Siegnist J (2009). Unlike most other land vertebrates, American alligators increase their speed through the distal rather than proximal ends of their limbs. Throughout the year (in particular during the breeding season), American alligators bellow to declare territory, and locate suitable mates. Such general rules include: Alligator in the Everglades National Park, Alligator in the Canberra Zoo in Australia, Juvenile alligator found in Everglades National Park. [48] Some American alligators are missing or have an inhibited gene for melanin, which makes them albino.

The victim's neighbor can be heard on a 911 call as Gloria Serge was dragged underwater. [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. Alligators first appeared during the Oligocene epoch about 37million years ago. Male alligators grow faster and larger than females. Georgia The state of Georgia is no stranger to Alligators, and that is particularly true for the southeast quadrant of the state. Reproduction [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.
