Alligators （短吻鳄） can be found in the wild in nearly half the counties in Texas，especially in the eastern part of the state，so residents and visitors may need a safety course about alligators．Although no deaths attributable to alligator attacks have been recorded in Texas during the past 15 years，17 people have reported injuries．It's against law to feed a free-ranging alligator，because after an alligator realizes that people are a source of food，it will become a problem animal．The alligator is a protected game animal in Texas，so special permits are required to hunt，raise or possess alligators．
TIPS FOR SAFETY AROUND ALLIGATORS：
l  Stay at least 30 feet away from an alligator．
l  Never Feed an alligator or leave food accessible．
l  Don't approach them or swim in areas where alligators have been seen．
l  During warm months，alligators are most active at dawn and dusk．
l  Alligators are common in swamps，rivers and muddy places．While typically found in fresh water，they can endure salty water．
