The American alligator lives in wetlands in southeastern United States from North Carolina to Texas. Wetlands are areas of standing water such as bogs, swamps, ponds, and marshes. Alligators mostly live in fresh water wetlands, but sometimes alligators live in brackish water. Brackish water is water that has more saline or salt water than fresh water.

The average temperature is 50 degree Fahrenheit a year and 40 to 60 inches of rainfall a year.
