The name «alligator» comes from the Spanish «el приведенная ссылка meaning lizard. English speakers, through mispronunciation, first converted the term to «aligarto» and later to «alligator. The reptile’s belly is creamy white, and its eyes are light brown. It can be differentiated from the American crocodile by its large, broad snout.

Unlike adults, young alligators have several yellow and white bands along their bodies. Alligators that shared the earth with dinosaurs million years ago looked almost the same and played similar ecological functions as their present-day relatives.

The largest alligator on record measured 5. Жмите, 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 where are the most alligators in south carolina – where are the most alligators in south carolina era.

Rice was introduced to Charleston, South Carolina, aroundresulting 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 по этой ссылке edge, and consist of a large mound of mud and crushed vegetation.

In the ACE Basin, most alligator nests are found where are the most alligators in south carolina – where are the most alligators in south carolina managed impoundments and, to a lesser extent, in remnant impoundments and unaltered marshes. 2022 timetable kenyan time 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 where are the most alligators in south carolina – where are the most alligators in south carolina 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. Hatchlings initially depend upon a yolk reserve but will begin feeding almost immediately on invertebrates such as insects, crustaceans, and snails and on small fish.

As they grow, larger foods such as snakes, larger insects and frogs become common. Adults feed on aquatic organisms and animals that come to the water’s edge to drink. In estuarine habits, the most common adult food item is blue crabs Callinectes sapidus.

Alligators are also known to feed on dead animals or carrion. Once alligators reach adulthood, they are top-level carnivores and have no natural predators. Raccoons Procyon lotorwading birds, and deer Odocoileus virginianus are prey items of the largest animals. In South Carolina, the harvest of American alligators for both food and leather remained unregulated until the s.

Inalligators benefited from a law, originally intended to protect deer, that banned night shooting. By the early s, in an effort to reduce poaching, alligator trappers were required by law to possess a license and tags. However, numbers of American alligators in South Carolina continued to decline, resulting in the closure of the season in Poaching continued even after inclusion of the species in the Endangered Species Protection Act of and the Endangered Species Conservation Act of Finally, inAmerican alligators were included under the Lacey Act ofwhich prohibited the transport of illegally collected mammals and birds across state boundaries.

Throughout the s and s, for scholarships students university a&m texas international continued to be protected under the Endangered Species Act of and were listed as endangered in coastal areas of South Carolina and threatened elsewhere in the state. Inthe U. Fish and Wildlife Service changed its status to one of «threatened upon similarity of appearance. Inthe S. This program was established in an effort to alleviate increasing human-alligator encounters due to rapid urban development in coastal areas.

After 31 years of closure, the alligator hunting season in South Carolina was re-opened in A permit, issued by the S. Department of Natural Resources and valid for one year, is required for the marketing and possession of any alligator product.
