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.
