Tiger salamanders inhabit a wide variety of ecosystems across North America. Given this geographic diversity, subpopulations of tiger salamanders exhibit morphological and behavioral diversity. Whether subpopulations constitute independent species or subspecies within the Ambystoma tigrinum complex, as well as the driving forces behind diversification, remains an active area of research as of 2024. Several subspecies within the Ambystoma tigrinum complex have been reclassified as an independent species.
