Ambystomatidae Family

The family Ambystomatidae is distinguished from other Idaho families of salamanders by the presence of transverse vomerine teeth

. More obvious characteristics are the presence of costal grooves (vertical creases along the body), and the absence of nasolabial grooves

(grooves running from the nostril to the lip). There are two representatives of the family Ambystomatidae here in Idaho: the Long-toed Salamander (Ambystoma macrodactylum) and the Tiger Salamander (Ambystoma tigrinum).
