The Jefferson salamander, Ambystoma jeffersonianum, is a mole salamander that lives in the northeastern United States, southern and central Ontario, and southwestern Quebec. It’s named after Jefferson College in Pennsylvania. They live in underbrush in deciduous forests in damp conditions. Physically, they are dark gray, brown, or black on its dorsal surface, with a lighter shade on their anterior, and some may have silver or blue specks on their sides. They are slender, with a wide nose and long toes. Larvae and adults are carnivorous and consume aquatic invertebrates, and insufficient food supply results in cannibalistic behavior.
