As many amphibians their are mostly nocturnal and they are hard to observe since apart of the breading season they spend most of their time underground in crevices and holes digged by other animals and amphibians. Long toed salamanders grow only in warm seasons and rings can be distinguished counted to determine their age. With this method, it is estimated that the lifespan of long-toed salamander in Canada can go over 8 years. Long toed salamanders feed on a wide range of preys consisting mostly of invertebrates and insects and their larvae eat zooplankton but sometime their also display cannibalistic behaviours..
