Jefferson's salamander is an amphibian from the ambystomatidae family. It lives in the forests of eastern North America, has a dark body and blue spots on the sides.
Jefferson's salamander differs from related species by the specific arrangement of blue spots and preference for certain forest water bodies. It is important for nature because it eats harmful insects and serves as food for birds and snakes. Its presence indicates the purity of forest ecosystems.
Immature form that undergoes metamorphosis before adulthood.
