In a fishless, sand bottomed pond with clear, clean water. ID using: http://fwf.ag.utk.edu/mgray/wfs493/HovermanLarvaeID.pdf - Also, the only species of salamander that has been seen in adult form in the area. However, I didn't see the blue-spotted salamander in the key and the habitat for that species is potentially available. Photos are probably not of the same individual. In the third photo, the salamander tries unsuccessfully to eat a large wormlike creature, possible some kind of leech.
