The spotted salamander (Ambystoma maculatum) is a mole salamander common in the eastern United States and Canada. It can reach 19 cm long and has yellow spots on its back. Their primary habitat are deciduous forests with fish-free ponds or vernal pools for egg laying and larval development. They feed primarily on invertebrates such as earthworms and slugs but will eat almost any insect they can get. They are primarily subterranean, but can also be found beneath surface debris.
