The San Antonio Zoo is working to save the Texas horned lizard. Researchers at the zoo are making progress in rebuilding the population of this iconic species. A recent development involves a mystery lizard, which may indicate success for the zoo's efforts.

The zoo has a "lizard factory" where this work is being done. Further details about the San Antonio Zoo's project to save the Texas horned lizard are available from the San Antonio Report, a local nonprofit newsroom.
