Does all the Eurycea larvae (longicauda/cirrigera to be specific) actually take 1-3 years to transform into a terrestial sallie?

Also, how do you know how far along they are? Mine are about 1/2"-ish and very short gills, they love to run from light and burrow under gravel.

*I know i have around 3 posts, but these questions are bugging me.

Hi Steve, longicuada usually take 4-8 months. E. cirrigera can take much longer, up to 3 years. There's really no way to tell how old they are for sure, you can only guess. But captivity usually makes them grow and therefore mature faster due to increased food supply, so you can shorten this period.

any way to know which larvae (longicauda/cirrigera) i have?

*also: they have all four legs and short gills.

I gave them around 3-4" water,planted,moss, and a rock to climb out, WILL they climb out and STAY out (on rock) when ready to be terrestial?

Wait, are these the same larvae we're having the Notophthalmus discussion about? If so, I highly doubt they are either.

If not, it's difficult to explain here. I've had larvae of both and can distinguish them in person, but I'd be hard-pressed to explain the differences to you here. As they approach metamorphoses though, they acquire the pattern of adults. So if cirrigera, they'll develop the two lines along the back typical of adults.

I don't know if it's too late, but try emailing Ronn Altig. He used to teach at Mississippi State University and specialized in the larvae of frogs and salamanders. You can email him at rga2@ra.msstate.edu
