This alligator and the American alligator are now considered to be sister taxa, suggesting that the A. mississippiensis lineage has existed in North America for seven to eight million years. [ 1 ] 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 ...

[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. The modern American alligator is well represented in the fossil record of the Pleistocene. [6] The alligator's full mitochondrial genome was sequenced in the ...
Wildlife officials shot the alligator, which was still holding the lifeless body of the boy 20 hours later. [44] [46] October 3, 1993 Grace Eberhart, 70, female: Florida — She was killed by one or more alligators at Lake Serenity, Sumter County. She died of a broken neck caused by an alligator bite to the throat and head. [44] [46] June 19, 1993
Articles relating to the genus Alligator. The two extant species are the American alligator (A. mississippiensis) and the Chinese alligator (A. sinensis). Additionally, several extinct species of alligator are known from fossil remains.
In the same year, 50 captive-bred crocodiles were released into the wild to help boost the population. Support from local people is crucial for the species' survival. [168] The American alligator has also undergone serious declines from hunting and habitat loss throughout its range, threatening it with extinction.
In fact, hypothetical models of alligator populations in the U.S. show that hunters would have to decrease the gator population by more than 90% in order to completely prevent human interaction ...
It was able to apply a bite force value of 3,700 lbf (16,000 N), and thus surpassed the previous record of 2,125 lbf (9,450 N) made by a 3.9 m (13 ft) long American alligator. [ 69 ] [ 70 ] Taking the measurements of several 5.2 m (17 ft) crocodiles as reference, the bite forces of 6-m individuals were estimated at 7,700 lbf (34,000 N). [ 71 ]
