Most of my wildlife photos came from one job. That job, in spite of allowing me a lot of time and access to wander around taking pictures, did have a goal: to find and document flatwoods salamanders on two state forests.
It had recently been discovered that the flatwoods salamander is actually two species, so recently that the current Petersen Field Guide to Reptiles and Amphibians still lists them as one species: Ambystoma cingulatum. A few years before I started the job, the populations west of the Apalachicola River were declared a separate species, the reticulated flatwoods salamander (Ambystoma bishopi). They were already rare as one species; this little offshoot was extremely rare. There were only about 36 known ponds where they had been found, and at many of those, none had been seen in years.
