Any ideas what species of salamander these are? Montague, Michigan, USA. It was near heavily wooded old forest on a dune, but the wetland from which they were taken, and mostly cattail-dominated marsh, was probably not part of the dune system since water runs down a tiny sluice out it into another (now dry) wetland, but still retains water.

Judging by the size, they're probably Tiger Salamander larvae. Most other salamanders morph out at half that size.

Josh-

Would almost certainly say it is a type of mole salamander? Tiger Salamanders, Spotted Salamander, and Blue-spotted Salamanders appear to be in the collection area, according to Jim Harding's Amphibians and Reptiles of the Great Lakes Region. I think I was told by Harding (by email) that Tiger Salamanders are not very common in Michigan. P

The larvae appear to be just over an inch, to my observance, though I don't know how close they are to really leaving water, except that they have all 4 legs.

Harding's book also says that Ambystoma t. tigrinum has a max larval length of 2.8 inches. A. maculatum gets to 1.6 to 3 inches when the morph. A. laterale metamorphose at 2.2-3.0 inches.

I can't determine what it is from the above data!

Give them a few weeks, they should start coloring up soon. Judging from your description I would expect Spotteds. Normally you can count coastal grooves but I think the count is identical between those two species. Either case they would normally be leaving the water here soon (not sure how late in the year in Michigan here in KY they would already be starting to leave).

IMO try to use some frozen food (blood,glass etc) or even cut up red worms instead of the pellets.


If a pet store says it, it must be true right?
