Salamander ID Help!

I've e-mailed photos of this larval salamander to several government agencies (F&W, NYSDEC) as well as some other people who are generally knowlegdeable with these things and have not been able to get an ID. As there are only a handful of mole salamander species on Long Island, the options (I'm pretty sure) are as follow:
Jefferson's
Blue Spotted
Tiger

Thanks in advance

Not to be funny, Luke, but: no spots, no stripes--must be a Jeffersons! I'm only half kidding...

Stan,

Your humor isn't lost on me. . . I hate trying to ID any non-mature aged animal as they always change so much (Don't get me started on tropical fish species). I've now been told that Jefferson's aren't on Long Island, so unless I'm missing something it's tiger or blue spotted, but the tiger should be significantly larger and the location I found them would make for a very isolated population of an endagered species. Hopefully someone can provide the answer!

When did you catch this specimen? If I know that i can tell you what it is.

Over the weekend - they are getting ready to lose the gills and walk out of the pond and into the ground

It is probably NOT a tiger salamander. Tigers breed in early autumn (oct) and early spring, so by this time the larva would be huge compared to that guy. Even if he was from a very early egg clutch from the past few days (unlikely) he'd still be tiny, without legs. Also, the other Ambystomid that occurs on LI is the Marbled Salamander (which this guy probably also is also not).

The blue spotted breeds in mid spring, so he would be getting ready to leave the water now.

Bryan,

That seems to make the most sense. Will try going there again this next weekend and hopefully find something a bit more distinct. Thanks for the info.
