5 Desmognathus species

• D. ochrophaeus• D. fuscus• D. monticola• D. quadramaculatus• D. welteri• Note: These are in increasing

order of water affinity so it will be helpful to look at the keel of the tail in each species

Cross Sections of Desmognathus Tails

specks along each side of the body• Head is usually brownish• Dark belly and body (except for the

chocolate head)• 14 costal grooves• STRONGLY KEELED TAIL
