The main threat facing the American alligator is the destruction and degradation of wetland habitat. Destruction of wetlands frequently occurs in association with human development.[1]
How Are Reptiles Affected By Global Warming?
Lizards, like other reptile species, are unable to regulate their own body temperature, which changes with air temperature. When the air temperature becomes too cold, lizards become immobilized. They often lose their grip on trees and fall stunned to the ground, making them vulnerable to predators.[2]
Are Crocodiles Affected By Climate Change?
According to a new study, climate change could lead to a huge population increase and diversification of crocodile species in North America and Europe. In the past, changing sea levels and global cooling over millions of years caused a significant decline in the number of crocodile species and their relatives.[3]
Why Do Alligators Need A Warm Climate?
Basking in the sun
Alligators have survived millions of years but need temperatures above 40 degrees to be active and can’t digest food if the temperature is below 70 degrees. Reptiles are coldblooded (ectothermic) and rely on external sources of heat to regulate their body temperature.[4]

Where Is The American Alligator Located?
The American alligator is found in the United States from North Carolina to the Rio Grande in Texas. Alligators are usually found in freshwater, slow-moving rivers. They also live in swamps, marshes and lakes. They can only tolerate salt water for brief periods because they do not have salt glands.[6]

There are also nearly 1 million alligators on farms in Louisiana.[8]
What Type Of Alligator Are In Louisiana?
American Alligator – Alligator mississippiensisOther Common Names:Subspecies: No subspecies recognized.Louisiana Range: Statewide, but records lacking from many parishes in west-central and northern Louisiana.Global Conservation Status: American Alligators are listed as Least Concern by the IUCN Red List.[9]
What Does An American Alligator Look Like
American alligator News. Both males and females have an ‘armored’ body with a muscular, flat tail. The skin on their back is armored with embedded bony plates called osteoderms or scutes. They have four short legs; the front legs have five toes while the back legs have only four toes.[10]
What Is An American Alligator Called?
The American alligator (Alligator mississippiensis), sometimes referred to colloquially as a gator or common alligator, is a large crocodilian reptile native to the Southeastern United States.[11]
Is There An American Alligator?
American alligators are large crocodilians found only in the United States. They can grow to be more than 12 feet (3.6 meters) in length and weigh as much as 1,000 pounds (450 kilograms), with males being slightly larger than females on average. The animal’s dark skin is armored with small, bony scales called scutes.[12]
What Is The Difference Between An American Alligator And An American Crocodile?
To distinguish the two, alligators have a more U-shaped snout while crocodiles have a more pointed or V-shaped one. In addition, alligators are black, while crocodiles are usually a lighter grayish brown. Learn More: American alligator (Alligator mississippiensis)[13]
How Big Is A Full Grown American Alligator?
Male alligators grow faster and larger than females. Females rarely exceed 9 feet in length and large females can weigh more than 200 pounds. Males rarely exceed 13 feet in length and large males can weigh well over 500 pounds.[14]
If An American Alligator Has Been Basking But Gets Too Hot, How Might The Alligator Cool Itself?
Swimming and Burrowing
The American alligator lives in wetlands, rivers, swamps and other freshwater sources, as well as brackish waters. The water helps him cool off when it becomes especially hot, or he’ll withdraw to whatever shade is available to become more comfortable.[15]
How Does An Alligator Cool Down?
It’s similar to a dog panting to cool down. Crocodilians have evolved to maximize heat gain and minimize water loss. Basically, they can’t sweat like we do to cool down. They evolved other methods of cooling, by opening their mouths and essentially sweating through their mouths.[16]
What Might An Alligator Do During Hot Weather?
To warm themselves, alligators bask in the sun, which is when they are frequently observed on the banks of water bodies. On hot summer days they can sometimes be seen basking with their mouths open. This is a cooling mechanism essentially equivalent to a dog panting.[17]
How Can Alligators Change Their Temperature?
Physiologi- cally, crocodilians increase cutaneous thermal conductance by increasing blood flow to the skin (and subdermal musculature) during warming. This hastens the warming process. Cutaneous blood flow is reduced during general cooling and locally if the body tempera- ture exceeds skin temperature.[18]
What Will Happen To The Alligator If Its Body Temperature Gets To Low?
When the water or air temperature is too low they go into a state of “brumation,” which means their metabolism slows down so much that the gators go into a lethargic state. During that time, the alligators will stay at the bottom of the body of water.[19]
American Alligator How Many Are Left
An estimated 5 million American alligators are spread out across the southeastern United States. Roughly 1.25 million alligators live in the state of Florida.[20]
Are American Alligators Endangered?
Least ConcernAmerican alligators were once threatened by extinction, but after being placed on the endangered species list in 1967, their population increased. This species is now classified as least concern. The main threat to these reptiles today is habitat loss caused by wetland drainage and development.[21]
How Many Alligators Does The U.S. Have?
There are about five million alligators in the U.S. Two million are in Louisiana, more than one million are in Florida, and the rest live among the other states.Sep 16, 2021[22]
Are Alligators Endangered 2022?
Alligators are no longer considered endangered. However, at one point, alligators were in great danger of extinction. From the 1800s through the mid-1900s, gators were often hunted for their skins, which were used in making leather. They were also poached for meat.[23]
Is The American Alligator Population Increasing?
The American alligator is a rare success story of an endangered animal not only saved from extinction but now thriving. State and federal protections, habitat preservation efforts, and reduced demand for alligator products have improved the species’ wild population to more than one million and growing today.[24]

Growth then slows slightly until age 10, when the alligator reaches approximately 8 feet in length. However, after 10 years, a female gator will have reached full size (9 feet), and a male alligator’s growth rate will slow considerably, growing less than an inch per year.Apr 2, 2019[27]
What Is The Longest American Alligator?
The largest reported individual size was a male killed in 1890 on Marsh Island, Louisiana, and reportedly measured at 5.84 m (19 ft 2 in) in length, but no voucher specimen was available, since the American alligator was left on a muddy bank after having been measured due to having been too massive to relocate.[28]
Can Alligators Grow Indefinitely?
For years, it was believed that American alligators continued growing in length until they died, what is called ‘indeterminate growth.’ But a 35-year study of a protected alligator population at the Yawkey Center on the South Carolina coast has found that male and female alligators exhibit ‘determinate growth.’ In …[29]
