An alligator, or colloquially gator, is a large reptile in the genus Alligator of the family Alligatoridae in the order Crocodilia. 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.
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 ...
The alligator gar (Atractosteus spatula) is a euryhaline ray-finned fish in the clade Ginglymodi of the infraclass Holostei / h oʊ ˈ l ɒ s t i aɪ /, being most closely related to the bowfins. It is the largest species in the gar family (Lepisosteidae), and is among the largest freshwater fish in North America.
The Chinese alligator split from the American alligator about 33 million years ago [8] and likely 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. [9] The alligator's full mitochondrial genome was sequenced in the 1990s. [10]
The habitat of the Chinese alligator is fresh water bodies, as pictured. The habitat of the Chinese alligator is bodies of fresh water, particularly wetlands and ponds, [2] in areas transitioning between subtropical and temperate climates. [22] It lives at the base of mountains, in areas where grass and shrubs are common. [34]
Alligator hunting is the capture and killing of gators. With the appropriate licenses and tags, the American alligator can legally be hunted in the Southeastern United States . The states of Florida , Georgia , Alabama , Arkansas , Mississippi , Louisiana , North Carolina , South Carolina , and Texas all distribute alligator hunting licenses.
Crocodiles (family Crocodylidae) or true crocodiles are large, semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia.The term “crocodile” is sometimes used more loosely to include all extant members of the order Crocodilia, which includes the alligators and caimans (both members of the family Alligatoridae), the gharial and false gharial (both ...
The Mexican alligator lizard (Abronia graminea), also known as the green arboreal alligator lizard, is an endangered species of lizard endemic to the Sierra Madre de Oaxaca highlands of Mexico. [ 3 ] [ 4 ] It can be found in the states of Puebla , Veracruz , and Oaxaca . [ 3 ]
