Habitat
These salamanders prefer inhabiting swampy woodlands, wet, damp, hardwood and deciduous forests. They are found in open fields and coniferous forests. During breeding season they tend to inhabit temporary pools where there is water till late summer. They tend to look for leaf litter, logs, rocks and under-brush for shelter round the year.
This salamander has a very unique adaptive feature. It lashes its tail back and forth. Then it swirls itself into within the tail. It secretes a toxin from its tail and releases into the predator’s mouth, when the predator tries to grab it. Even if the predator survives that toxin and still holds on to the tail, then the salamander shreds its tail off from itself. The tail grows back again later with time.

Reproduction
Blue spotted salamanders start reproductive interactions since the age of 2 years. They choose one of those abandoned temporary ponds as their mating site. The male salamander rubs his chin on head of the female, grabbing her close to him by his front limbs. Then he leaves some germ-cells on the bottom of the pond and positions the female above the place where his germ-cells are. The female takes those germ cells inside her body and her eggs germinate.
Female salamanders attach their eggs behind some rocks or rooted aquatic plants and not floating ones in order to keep the eggs from the sight of their predators. These salamanders lay about 490 eggs every year. The eggs hatch almost after a month after laying.
