Eastern newts (Caudata: Salamandridae: Notophthalmus viridescens) are relatively common throughout most of the eastern US and southeast Canada. They are typically found in ponds or moist woodlands, depending on their life stage. The gilled larvae and fully-developed adults are aquatic, but juveniles like the one shown here are terrestrial.
Known as “efts,” these juveniles are much more brightly colored than the drab adults. As is often the case in nature, these colors warn potential predators of their toxic secretions. Since the conspicuous efts wander considerable distances over land with impunity, they’re the life stage most commonly encountered by people.
