Help ID Ambystoma species (larvae and metamorphosed pictures)

[James87]

Hello. I thought this larvae collected (on summer solstice) was A. tigrinum; however now that it has morphed (just a couple days ago), I am having my doubts.
It is around 4.5" long. Still appears to have a mottled yellow/black tail, dark gray/olive back, and grayish blue sides. Perhaps a hybrid of some sort? It was collected from Northwest Indiana. I am sorry for being a total n00b. Attached are low quality cell-phone photos which I hope can help. Thanks in advance for any help or information!

Jefferson's salamander, Ambystoma jeffersonianum.

Thank you.. I thought that perhaps it was a jefferson or blue-spotted hybrid but was unsure because if its large-ish size for just morphing. Will the coloration develop more in the next couple of weeks?

 

[Kaysie]

It will. Some Jeffersons aren't that heavily mottled, so it might not change much.

IMO it looks like you have a blue spotted salamander, though it is hard to tell...I had some larvae I caught a few years back that I had a hard time identifying, thought they were Jefferson's when they started to morph and looked exactly like your photos, but in a couple of weeks darkened and the blue spots came out...
