In 1989, genetic studies showed D. copei to be a distinct species, and the D. ensatus populations to consist of three species: the Idaho giant salamander (D. aterrimus) in Idaho, and two highly divergent species with a narrow hybrid zone in California, the coastal giant salamander (D. tenebrosus) (ranging from northern California to Washington ...
The coastal giant salamander can reach up to 33 cm (13 in) in total length as a terrestrial adult, and 35.5 cm (14.0 in) in paedomorphic forms, [4] making it the largest terrestrial salamander in North America. [5] The coastal giant salamander has stout limbs with four toes on the front feet and five toes on the back feet.

There are three closely related species to this taxon: D. ensatus (California giant salamander), D. aterrimus (Idaho giant salamander) and D. tenebrosus (coastal giant salamander).
