Northern Zigzag Salamander vs. Northern Ravine Salamander

A Zigzag usually has a wavy-edged stripe; a Ravine never does. Dark Zigzags have no stripe, so look at the armpit: a red or orange patch where the front leg meets the body means Zigzag. A Ravine is plain dark with fine silvery flecks, long and thin with short legs.
