Found these in 2-6 inches of water under rocks.
They are 2-3 inches long.
The water was cold.
Found in SE Pennsylvania.
There are salamanders in the area so this might be larval stage but I though they were juvenile mudpuppies.
Could they be larvae left over from last year?

Mudpuppies are not native to SE PA.
Depending on where in SE PA you found them they could be a number of species.

appear to be Gyrinophilus porpyriticus

The lighter colored, slender animals with rows of dorsal light spots in the first photo are Two-lined Salamander (Eurycea cirrigera or E. bislineata, I'm not sure which occurs in your area)larvae; the larger animals are probably Spring Salamander (Gyrinophilus porphyriticus) larvae. Both of these species have long larval stages.

Mudpuppies (Necturus maculosus) are found in rivers and lakes, not in small streams, and have four toes on each hind foot. Mudpuppy larvae small enough to be confused with those other salamanders have distinctive longitudinal black stripes. They can be found in your area, mainly in tributaries to the Ohio River.
