The largest alligator on record measured 5. However, such large and heavy animals are quite uncommon. They also inhabit wetland areas in Texas, Oklahoma, and Arkansas. In South Carolina, American alligators make extensive use of the state's coastal marshlands, with the ACE Basin being one of the most important nesting areas. High quality alligator habitat found on the coast was created as a result of wetland alteration during the rice-growing era. Rice was introduced to Charleston, South Carolina, around , resulting in the clearing of forested, tidal swamps.
Ditch and dike construction permanently altered natural drainage patterns and caused extensive change in wetland plant communities.
After the rice industry's demise in the early s, abandoned, diked fields began to deteriorate; however, some dikes and water-control structures were repaired and maintained by sportsmen as waterfowl hunting areas. Today, these impoundments support the highest alligator population and nest densities found in the ACE Basin and the state.
Alligator populations gradually decline inland because habitats are seasonally flooded and prey density is reduced. American alligators are cold-blooded animals, but generally are active year round in South Carolina. Breeding season for the American alligator varies throughout its range because the onset coincides with warmer weather. Nest site selection, construction, maintenance, and protection are important activities in the life of a female alligator.
In South Carolina, the majority of nest construction and egg laying takes place during the month of June. Nests are located on high ground, 1 to 5 meters 3 to 18 ft from the water's edge, and consist of a large mound of mud and crushed vegetation. In the ACE Basin, most alligator nests are found in managed impoundments and, to a lesser extent, in remnant impoundments and unaltered marshes.
Most nests within impoundments are located on remnant dikes. Nest material is from surrounding vegetation, which is typically giant cordgrass Spartina cynosuroides and nests are about 1. Once the mound is complete, the female digs a conical chamber in the center of the mound and deposits eggs into the chamber.
Several layers of mud and vegetation are then added and compacted atop the egg chamber. Inside it, the eggs are kept at a constant temperature as a result of heat produced by decomposition of the nesting material. Sex of alligators is determined by nest temperatures during the middle third of embryo development. Females are produced at temperatures less than Decreasing numbers of males are produced as temperatures approach 35oC, a temperature beyond which only females are produced.
Incubation periods average between 63 and 65 days, but can be as long as 77 days. Hatchling alligators average about 24 cm 10 in in total length and weigh g 1. After hatching, juvenile alligators remain together in a group called a pod or creche, which may remain together for up to three years. Both sexes grow to about cm 4 ft by age 5. After this age, female growth begins to slow, presumably channeling energy towards reproduction, while males continue to grow fairly rapidly.
By age 25, males on average measure cm 10 ft 4 in and females average cm 8 ft 3 in. Males can reach lengths greater than cm 13 ft while females rarely exceed cm 9 ft 6 in. Males and females become sexually active when approximately 2. Alligator food habits vary by size class, with prey size increasing as alligators get larger.
The season is regulated as a quota hunt and requires an application and permitting process. Hunters, who are only permitted for one season at a time, are only allowed to take one individual each year. Conservation Challenges: Alligator populations are considered to have recovered from overharvesting pressures through supplemental farming practices and the reduced take of wild animals.
However, alligators face plenty of challenges in our present-day landscapes. Expanding development in their habitat and the colonization of stormwater freshwater catchment lagoons along golf courses has forced an increase in interactions with resident humans. Since alligators cannot be relocated, all calls from property owners requesting removal result in the harvest of that animal. As human populations increase in these areas and tourism booms along coastal habitats, there are more and more situations where alligators are being fed and therefore, must ultimately be removed from the population.
This situation is confounded by the fact that alligators have a bad albeit biologically inaccurate reputation from people misinterpreting the actual risk of alligator encounters.
Aside from problem interactions with humans, alligators are also experiencing direct habitat loss from development and the effects of pollution. Contaminants such as mercury and pharmaceuticals have led to decreased water quality and physiological effects in alligators exposed to these pollutants. The future of the alligator lies in the hands of the people who live around alligators; their support is crucial in the development and implementation of long-term conservation and management of alligators and their habitats.
How to Be Safe Around Alligators. Did you know? Send your suggestions, comments, or questions to: srelherp gmail. Herp Home. SREL Home. Alligators and their relatives are the last of the living reptiles that were closely related to dinosaurs, and their closest modern kin are birds. There is only one other alligator species, the Chinese alligator. Alligators and crocodiles are related. However, alligators have rounded snouts, while most crocodile species have longer, pointed snouts.
Also, crocodiles occur only in tropical and subtropical areas only south Florida in the United States , while alligators live in somewhat colder climates. The incubation period lasts about 65 days, during which the mothers defend the eggs against predators.
American alligators have a typical lifespan of about years; alligators in captivity can live up to 80 years. Some alligators die when much younger, and once they are about four feet long, they are safe from most predators apart from other alligators and humans.
The teeth are also replaced constantly throughout their life; when they wear down, new teeth grow in. American alligators could go through teeth in their lifetime, as they get replaced if they break or wear down.
While alligators thrive in many lakes in South Carolina, Lake Marion is the most infested. Over alligators are confirmed to live in Lake Marion, and alligators weighing up to pounds are found in the lake. They venture into brackish salt water and move back and forth from freshwater to marine ecosystems to balance the salt levels in their bodies. They protect them fiercely and will attack intruders if they believe they are a threat to their eggs.
All crocodile species have V-shaped snouts that could vary from narrow to broad but maintain the pointed shape. Alligators are smaller, with most 8 to 11 feet long with a weight of to pounds, with the male alligators being larger than their female counterparts. While the crocodiles are enormous, it is often challenging to tell the two species apart through their size, and it is difficult to eyeball.
Alligators live in lakes, low-flowing rivers, ponds, and swamp lands; they prefer living closer to the shore. They cannot survive in salt water, and the most they can do is move in and out of freshwater and saltwater ecosystems.
There are only two alligator species, with the American alligator the only one available in South Carolina. Crocodiles have shades of black, brown, grey, and green.
Their bodies have mottled patterns, which help them blend well with substrate and algae. If you hear an alligator hissing, it is a warning sign that you are too close for comfort; walk away.
The only native alligator species in the state is the American alligator which has a lifespan of up to 50 years and 80 years when domesticated. Alligators get aggressive when they feel threatened, and it is crucial to take the necessary safety precautions.
You can hunt alligators in South Carolina during the designated hunting season if you have a permit and harvest tag.

By age 25, males on average measure cm 10 ft 4 in and females average cm 8 ft 3 in. Adults feed on aquatic organisms and animals посетить страницу come to the water's edge to drink. This studies prolong documentation of growth rates, along with several other growing studies point toward the more newly supported pattern of determinant growth in the American alligator. 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 and their habitats.

The mother defends the nest against predators throughout the incubation period, approximately 65 days. When the eggs are ready to hatch, the mother alligator digs into the nest mound, opens any eggs that have not hatched, and carries the young down to the water. Females sometimes aggressively defend their young for more than a year.
Mother alligators that are killed or removed from the area cannot defend their nests or young, and the hatchlings often are doomed. If the young escape predation and can find enough food, they may grow between 3 and 8 inches in length yearly.
When they reach lengths of about 6 feet, they are considered adults. With the start of their breeding season in May, male alligators "bellow" to females and other males in the area. When the eggs hatch, the mother alligator digs into the nest, opens any eggs that have not hatched, and carries the young down to the water. Prey: Alligators are opportunistic feeders; adults eat fish, turtles, wading birds, snakes, frogs, small mammals and even smaller alligators they find near the shoreline of their habitat.
Young alligators feed on small fish and aquatic invertebrates, but in turn, they can be food for raccoons, crabs, large snakes, turtles, various types of wading birds and even fish. They have recorded population sizes, genetic patterns, distribution patterns and long-term population trends; animal sizes, sexes, activity periods, growth rates and reproductive efforts; diet, nutrition and energetics; responses to thermal effluent from reactors into cooling reservoirs; uptake of radionuclides; and the conservation of the species.
Currently, SREL researchers work with alligators through long-term mark-recapture surveys, characterization of mating and paternity systems, and through studies on the effects of contaminants in long-lived reptiles. Alligators are easily spotted at night by the shine of their eyes in the beam of a headlamp. For this reason, biologists often conduct nocturnal surveys. Game hunters found the gator in Lake Moultrie, known for housing the biggest gators in the state today.
The American alligator Alligator mississippiensis of the Family Alligatoridae is the only species native to South Carolina. While previously listed as endangered, their populations have rebounded and are currently doing so well. In , the Department of Natural Resources initiated a program to allow contracted trappers to remove aggressive gators aggressive to domesticated animals and humans or invaded recreational areas. As the population grew, the Department of Natural Resources initiated a hunting season, as plenty of the species existed.
While it is safe to swim in swimming pools in South Carolina, avoid swimming in natural waters, especially ones that are known to harbor reptiles. Swimming in these water sources often attracts alligators as they think a prey is injured when you splash.
Protective mothers can also attack instinct as they believe their nests or young ones are in danger. Swimming between dusk and dawn puts you in danger, as the reptiles are active at night. If it is not a designated swimming area, other looming hazards include stumps, steep drop-offs, rocks, and other obstructions. For safe swimming in South California , pay attention to swimming advisory signs warning against alligators before venturing into natural waters. Never swim alone, and be careful when around water; this is not only to give you a fighting chance against alligators but also as a standard safety precaution.
After dolphins, alligators are the most popular wildlife attraction in coastal areas of South Carolina. The state is home to over , predators, which everyone visiting the state wants to see. You can observe the reptiles from a distance or through safer means, like embarking on a guided alligator tour, visiting the South Carolina aquarium, or going for an alligator adventure. Then with a quick burst of speed, the alligator will grab the prey with its teeth, exerting over 3, lbs of pressure per square inch.
From there the alligator will pull its prey down to drown it. Once the prey is dead it is swallowed whole. Though alligators have very powerful bites, they lack serious strength in opening their mouths. Once their mouths are closed, they can be kept closed with a thick rubber band DO NOT try this at home.
The American alligator was once almost extinct because they were hunted for their meat and skin.
