how far north do alligators live

"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 ! [44] Some American alligators are missing or have an inhibited gene for melanin, which makes them albino. 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. Black caiman, Charles, S.; Ross, A. and Garnett, Stephen (1989). [76] In the 2000s, when invasive Burmese pythons first occupied the Everglades, alligators have been recorded preying on them, possibly controlling populations, thus preventing the invasive species from spreading northwards. [22] As American alligators grow and develop, the morphology of their teeth and jaws change significantly. Nyman, T. McFalls, J. Carter and J. Siegrist (2009). This alligator and the American alligator are now considered to be sister taxa, meaning that the A. mississippiensis lineage has existed in North America for over 8 million years. Young are born with yellow bands around their bodies and are protected by their mother for up to one year.[10]. [41] In the saltwater crocodile, for example, the females are only slightly larger at average (2.4 m (7 ft 10 in) in the American alligator, 2.6 m (8 ft 6 in) in the saltwater crocodile) than female American alligators, but the mature males, at 4.3 to 5.2 m (14 ft 1 in to 17 ft 1 in) typically, as opposed to 2.4 to 4 m (7 ft 10 in to 13 ft 1 in) expected in mature male American alligators, are considerably bigger than male American alligators and at median are nearly twice as long as and at least four times as heavy as the female saltwater crocodiles of the same species. [55], Historically, hunting and habitat loss have severely affected American alligator populations throughout their range, and whether the species would survive was in doubt. It is distinguished from the sympatric American crocodile by its broader snout, with overlapping jaws and darker coloration, and is less tolerant of saltwater but more tolerant of cooler climates than the American crocodile, which is found only in tropical climates. As human populations increase, and as they build houses in low-lying areas or fish or hunt near water, incidents are inevitable where humans intrude on American alligators. [118] Allegheny College and San Francisco State University both have Gators as their mascots, as well.[119]. How far is raleigh north carolina from charlotte north carolina? Protection under the Endangered Species Act allowed the species to recuperate in many areas where it had been depleted. [69][70], American alligators are considered an apex predator throughout their range. Fossils identical to the existing American alligator are found throughout the Pleistocene, from 2.5 million to 11.7 thousand years ago. [49] In the water, American alligators swim like fish, moving their pelvic regions and tails from side to side. Leidyosuchus of Alberta is the earliest known fossil, from the Campanian era 83 to 72 Mya. In 1807, Georges Cuvier created the genus Alligator;[11] the American alligator and the Chinese alligator are the only extant species in this genus. American alligators bellow in B flat (specifically "B♭1", defined as an audio frequency of 58.27 Hz), and bellowing choruses can be induced by tuba players, sonic booms, and large aircraft.[98]. [84] Additionally, American alligators engage in what seems to be cooperative hunting. In May 2006, American alligators killed three Floridians in less than a week. The American alligator is capable of biting through a turtle's shell or a moderately sized mammal bone. But, in fact, they already range a long way up from Florida. [22] The largest reported individual size was a male killed in 1890 on Marsh Island, Louisiana, and reportedly measured at 5.84 m (19 ft 2 in) in length, but no voucher specimen was available, since the American alligator was left on a muddy bank after having been measured due to having been too massive to relocate. [63] 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. The conservation status of the American alligator is listed as least concern by the International Union for Conservation of Nature. [20] Meanwhile, their undersides are cream-colored. There are two different types of alligator, and they vary in size. [61] 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. 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. This is not often seen, since if disturbed, they quickly retreat back into the water by jumping from their perch. In that year, a printer made a spur-of-the-moment decision to print an alligator emblem on a shipment of the school's football pennants. [99] The female builds a nest of vegetation, sticks, leaves, and mud in a sheltered spot in or near the water. [45], The teeth number 74–80. ", "Climbing behaviour in extant crocodilians", "American Alligator Ecology and Monitoring for the Comprehensive Everglades Restoration Plan", "Characterization of Natural and Artificial Alligator Holes", 10.1656/1528-7092(2004)003[0583:CONAAA]2.0.CO;2, WEC203/UW230: Living with Alligators: A Florida Reality, "Crocodiles are cleverer than previously thought: Some crocodiles use lures to hunt their prey", "Alligators Attack and Eat Sharks, Study Confirms". American alligators are apex predators and consume fish, amphibians, reptiles, birds, and mammals. [90] Their vocal folds consists of epithelium, lamina propria and muscle. In 2018, several sightings of animals that had moved north into West Tennessee were confirmed. [114] 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. There are approximately 200,000-250,000 alligators in the state of Georgia. Recently a seven-foot alligator was videoed by TWRA Region 1 personnel in West Tennessee at the Wolf River WMA in Fayette County.
