What is a nuisance alligator? Generally, an alligator may be considered a nuisance if it is at least four feet in length and is believed to pose a threat to people, pets or property.
Physiology[ edit ] When on land, an American alligator moves either by sprawling or walking, the latter involving the reptile lifting its belly off the ground. The sprawling of American alligators and other crocodylians is not similar to that of salamanders and lizards, being similar to walking.
Therefore, the two forms of land locomotion can be termed the "low walk" and the "high walk". Unlike most other land vertebrates, American alligators increase their speed through the distal rather than proximal ends of their limbs.
It was found that there is no significant difference between the bite forces of male and female American alligators of equal size. In there were several confirmed sightings of animals that had moved north into West Tennessee.
A lone American alligator was spotted for over ten years living in a river north of Atlanta, Georgia. While they prefer fresh water, American alligators may sometimes wander into brackish water,  but are less tolerant of salt water than crocodiles, as the salt glands on their tongues do not function.
During summer, males still preferred open water, while females remained in the swamps to construct their nests and lay their eggs. Both sexes may den underneath banks or clumps of trees during the winter.
This behavior has qualified the American alligator to be considered a keystone species. Alligator holes retain water during the dry season and provide a refuge for aquatic organisms.
Aquatic organisms that survive the dry season by seeking refuge in alligator holes are a source of future populations. The construction of nests along the periphery of alligator holes, as well as a buildup of soils during the excavation process, provide drier areas for other reptiles to nest and a place for plants that are intolerant of inundation to colonize.
Alligator holes are an oasis during the Everglades dry season, so are consequently important foraging sites for other organisms. American alligators also may control the long-term vegetation dynamics in wetlands by reducing the population of small mammals, particularly coypuwhich may otherwise overgraze marsh vegetation.
American alligators prevent predatory mammals from reaching island-based rookeries and in return eat spilled food and birds that fall from their nests. Wading birds appear to be attracted to areas with American alligators and have been known to nest at heavily trafficked tourist attractions with large numbers of American alligators, such as the St.
Augustine Alligator Farm in St. This is not often seen as the American alligators will retreat back into the water by jumping from their perch. They are opportunists and their diet is determined largely by both the size and age of the American alligator and the size and availability of prey.
Most American alligators will eat a wide variety of animals, including invertebratesfishbirdsturtlessnakesamphibiansand mammals.
Hatchlings mostly feed on invertebrates such as insects, insect larvaesnailsspidersand worms. As they grow, American alligators gradually expand to larger prey.
Once an American alligator reaches adulthood, any animal living in the water or coming to the water to drink is potential prey, due to the size and power of the American alligator. Most animals captured by American alligators are considerably smaller than the American alligator itself.
Occasionally, domestic animals, including dogscatsand calvesare taken as available, but are secondary to wild and feral prey. Occasionally, unwary adult birds are grabbed and eaten by American alligators, but most predation on bird species occur with unsteady fledgling birds in late summer as the prey of American alligators, as fledgling birds attempt to make their first flights near the water's edge.
Unusually in these regions, reptiles and amphibians were the most important non-piscivore prey, mostly comprised by turtles and water snakes.
Usually, terrestrial hunting occurs on nights with warm temperatures. The American alligator is capable of biting though a turtle's shell or a moderately sized mammal bone.
Sharks are also known to prey on American alligators in turn, indicating encounters between the two predators are more common than thought.
InAmerican alligators and other crocodilians were reported to also eat fruit. The discovery of this unexpected part of the American alligator diet further reveals that American alligators may be responsible for spreading seeds from the fruit it digests across its habitat.
By balancing sticks and branches on their heads, American alligators are able to lure birds looking for suitable nesting material to kill and consume. This strategy, which is shared by the mugger crocodileis particularly effective during the nesting season, in which birds are more likely to gather appropriate nesting materials.Aug 15, · The randomly-chosen permits will allow the use of anything from hand-held ropes to bow and arrows to hunt for alligators between September 1 and October 1.

An alligator is a crocodilian in the genus Alligator of the family grupobittia.com two living species are the American alligator (A. mississippiensis) and the Chinese alligator (A. sinensis).Additionally, several extinct species of alligator are known from fossil remains.
Alligators first appeared during the Oligocene epoch about 37 million years ago.. The name "alligator" is probably an. TWRA would like to remind everyone that alligators are a protected species and catching or shooting one is a violation of the law.
If you come across one while exploring the outdoors in West TN, leave it alone and enjoy Tennessee’s unique biodiversity. Juveniles: Small alligators are eaten by a variety of predators including raccoons, otters, wading birds, and fish; however, larger alligators may be their most significant predator.
Adults: Cannibalism, intraspecific fighting, and hunting by humans are probably the most significant mortality factors.
