>>19756408Quagsire is based on a giant salamander yes, but I think you confused my post; the giant salamander doesn't have the external gills that the axolotl has and the tiger salamander has in its larval stages.
The only thing Swampert shares with the giant salamander is immense size and being amphibian.
In addition, Swampert resembles the mudpuppy for exactly the same reason as it does the axolotl, and shares the fin similarity with the mudskipper.
