There are many turtles, native or nonnative, commonly kept in captivity in Arizona.  Often these turtles escape or are unlawfully released, meaning that you may find one in your neighborhood or even in the wild.  This website will help you identify a turtle that you may have found, and provide information on what you should do with it.  Because there are more exotic species than native found in residential areas, this site is mostly geared towards nonnative (exotic) species that are commonly encountered.  If you find a turtle in the wild, as opposed to a residential area, the best thing to do is to let it be.  Our native species are protected and most cannot be collected, even with a hunting license.  See current regulations at www.azgfd.gov.
