I found this Redbacked Salamander while visiting NH recently. I found this guy after only about 5 minutes of searching. I’m told they are not hard to find if you look in the right place: he was under a rock. I released it after a brief photo shoot.
This salamander is called a Northern Redback Salamander, as well as, an Eastern Red-backed Salamander (Plethodon cinereus). It can also be found in Maryland but I haven’t found one here yet.
Note the four toes in the back and the three in the front.
