My favorite group of salamanders, and one of my favorite herp groups in general1 I look forward to the photos.
Here is my contribution:
All the following were found in Ohio.
Eastern Tiger Salamander (Ambystoma tigrinum)
Jefferson Salamander (Ambystoma jeffersonianum)
Small-mouthed Salamander (Ambystoma texanum)
Streamside Salamander (Ambystoma barbouri)
Spotted Salamander (Ambystoma maculatum)

Normal and purple Spotted Salamanders
Marbled Salamander (Ambsytoma opacum)
Hybrids from the Kelley’s Island, Ohio. Tiger, Smallmouth, Bluespot, Jefferson and Streamside genes in the population.

Same as above, with this one showing lots of Tiger genes.
All the following are not from Ohio.
Arizona Tiger Salamander (Ambsytoma mavortium nebulosus) from Gunnison, Co.

Failed to photo larvae of A.m. melanostictum in Yellowstone.
Mole Salamander (Ambystoma talpoideum) from S. Illinois.
Also failed to photo Blue-spotted Salamander far north in Quebec. And that is it for me and Ambsytoma.
