What is the difference between a mudpuppy and an axolotl?
Mudpuppies have a few doppelgangers that people always get confused. The most notorious look-alike is the ever-popular axolotl. The axolotl is another type of salamander that does not do metamorphosis, and as such it has external gills just like the mudpuppy. They are not related, however.
Do mudpuppies bite?
