Spotted Salamander (Ambystoma maculatum)

The Spotted Salamander, also called Yellow-spotted Salamander, lives in the forests of eastern North America. Their yellow or orange spots warn predators of their toxicity and help them blend in with the forest floor. 

Moreover, they are active at night, eating insects and other invertebrates, which helps keep pest populations in check. They mostly live underground and will come out to eat or breed.
