None were fatal. Exaggeration, you say? [38] In Lake Griffin State Park, Florida, adults weighed on average 57.9 kg (128 lb). To capture prey, they quickly snap their head to the side and grab it with their large teeth. [4][5][6][7][8] The American alligator inhabits freshwater wetlands, such as marshes and cypress swamps from Tamaulipas in Mexico to southeastern and coastal North Carolina. On a historical note, in his 1950 book, Steamboating: Sixty-Five Years on Missouri’s Rivers, Captain Bill Heckman reported the largest fish ever caught in the Missouri River was a blue catfish. Staff Writer - Larry Archer The Chinese alligator likely descended from a lineage that crossed the Bering land bridge during the Neogene. [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. 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]. [101] They are preyed on by large fish, birds, raccoons, Florida panthers, and adult American alligators. Sharks are also known to prey on American alligators, in turn, indicating encounters between the two predators are common. Killed by Max Touchet, a game warden on Marsh Island following an attempted live capture. 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. [18][19], As with all crocodilians, and as opposed to many mammals where size eventually diminishes with old age, healthy American alligators may continue to grow throughout their lives and the oldest specimens are the largest. [7][8] In Newnans Lake, Florida, adult males averaged 73.2 kg (161 lb) in weight and 2.47 m (8 ft 1 in) in length, while adult females averaged 55.1 kg (121 lb) and measured 2.22 m (7 ft 3 in). 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. [40], While noticeable in very mature specimens, the sexual dimorphism in size of this species is relatively modest among crocodilians. [106] They may provide a protection service for water birds nesting on islands in freshwater wetlands. Lake sturgeon have a shark-like tail, a sucker-like mouth underneath the head, and four large barbels (or whiskers) that dangle under the nose. 9 p.

[24] The largest American alligator ever killed in Florida was 5.31 m (17 ft 5 in), as reported by the Everglades National Park. 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. No, there’s not an alligator in Big Lake. Tackle boxes, rods and reels, seat cushions, and bait buckets went flying as we scrambled around the boat to pull up the anchors and find the dip net. [50] During respiration, air flow is unidirectional, looping through the lungs during inhalation and exhalation;[51] the American alligator's abdominal muscles can alter the position of the lungs within the torso, thus shifting the center of buoyancy, which allows the American alligator to dive, rise, and roll within the water. [18] A specimen that was 4.8 m (15 ft 9 in) long and weighed 458.8 kg (1,011.5 lb) is the largest American alligator killed in Alabama and has been declared the SCI world record in 2014. In 2018, several sightings of animals that had moved north into West Tennessee were confirmed. [44] Some American alligators are missing or have an inhibited gene for melanin, which makes them albino. On Mingo NWR, alligator gar must be released unharmed immediately after being caught. Usually, terrestrial hunting occurs on nights with warm temperatures. The officer also noted there are several semi-submerged logs in the lake. Call 1-800-392-1111 to report poaching and arson. [117] Several organizations and products from Florida have been named after the animal. [22], Adult American alligators held the record as having the strongest laboratory-measured bite of any living animal, measured at up to 13,172 N (1,343.2 kgf; 2,961 lbf). 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. F. Wayne King, John Thorbjarnarson and Carlos Yamashita. Fish and Wildlife Service pronounced the American alligator fully recovered. 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. 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. No matter your choice of fishing method or bait, you’re in for a lot of fun if you hook into one of these monsters. Flathead catfish typically occur in the large rivers and lakes in Missouri. [102][103][104], American alligators play an important role in the restoration of the Everglades as biological indicators of restoration success. One exception is that blue catfish will readily take cut bait, where flathead catfish usually do not. The nests built on levees are warmer, thus produce males, while the cooler nests of wet marsh produce females. The Gatornationals is a NHRA drag race held at the Gainesville Raceway in Gainesville since 1970. [73] Rarely, American alligators have been observed killing and eating bobcats, but such events are not common and have little effect on bobcat populations. The paddle-shaped snout, which is covered with sensory organs, is thought to assist with finding food. This behavior has qualified the American alligator to be considered a keystone species. [9] Male American alligators use infrasound to attract females. 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. 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. The goal of those stockings was to restore alligator gar to some of its native range in Missouri. Such incidents usually involve a panther trying to cross a waterway or coming down to a swamp or river to get a drink. Smaller blue catfish eat a variety of food including aquatic insects, crayfish, and mussels. Very old, large male American alligators reach an expected maximum size up to 4.6 m (15 ft 1 in) in length and weighing up to 453 kg (999 lb), while females reach a maximum of 3 m (9 ft 10 in). Even with medical treatment, an American alligator bite may still result in a fatal infection.[109]. They cause serious damage to coastal marshes and may dig burrows in levees. The Missouri rod-and-reel state record was caught in Montrose Lake in 2003 and weighed 77 pounds, 8 ounces. Most catfish anglers will tell you that there is nothing like the feeling of fighting one of these huge fish! 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. [22] Stomach contents show, among native mammals, muskrats and raccoons are some of the most commonly eaten species. 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. In one experiment conducted on the larynx, the fundamental frequency depended on both the glottal gap and stiffness of the larynx tissues. Throughout the year, in particular during the breeding season, American alligators bellow to declare territory and locate suitable mates. To capture prey, they quickly snap their head to the side and grab it with their large teeth.

[20][21], During the 19th and 20th centuries, larger males reaching 5 to 6 m (16 ft 5 in to 19 ft 8 in) have been reported. Young are born with yellow bands around their bodies and are protected by their mother for up to one year.[10].
