What primary respiratory surfaces does the newt use across its different life stages?

Gills (larval stage), lungs, and skin
The newt transitions from breathing primarily through gills in its aquatic larval form to utilizing both lungs and cutaneous respiration (breathing through the skin) as an adult, requiring cardiovascular adjustments.
