Dicamptodon
The Pacific giant salamanders are members of the genus ''Dicamptodon''. They are large salamanders endemic to the Pacific Northwest in North America. They are included in the family Ambystomatidae, or alternatively, in their own monogeneric family Dicamptodontidae. Description Pacific giant salamanders are defined by their wide protruding eyes, costal grooves, thick arms, and dark background coloring. ''Dicamptodon'' have a snout-vent-length (SVL) of , a broad head, laterally flexible flattened tails, paired premaxillae that are separate from the nasals, and the aquatic larvae have gills. ''Dicamptodon'' have lacrimals and pterygoids that are present, but quadratojugal are absent. While most salamanders are silent, the Pacific giant salamander is one of several salamanders that have vocal abilities. When startled, these salamanders may respond with a croaky-sounding cry similar to that of a barking dog. Habitat Pacific giant salamanders are semi-aquatic animals that occupy ...

California Giant Salamander
The California giant salamander (''Dicamptodon ensatus'') is a species of salamander in the family Ambystomatidae. ''Dicamptodon ensatus'' is endemic to California, in the western United States. The species once additionally included individuals now belonging to the species ''D. aterrimus'' ( Idaho giant salamander) and ''D. tenebrosus'' ( coastal giant salamander), under the common name Pacific giant salamander, which now refers to the genus and family. Taxonomy The Pacific giant salamander (''D. ensatus'') was thought to consist of three geographic populations: an Idaho group, a group in northern California, and a group in Oregon and Washington. In 1989 genetic studies showed that the ''D. ensatus'' populations consisted of three species: the Idaho giant salamander (''Dicamptodon aterrimus'') in Idaho, and two highly divergent species with a narrow hybrid zone in California, the coastal giant salamander (''Dicamptodon tenebrosus'') (ranging from northern California to Washi ...

Coastal Giant Salamander
The coastal giant salamander (''Dicamptodon tenebrosus'') is a species of salamander in the genus ''Dicamptodon'' (Pacific giant salamanders). It is endemic to the Pacific Northwest of North America. There are three closely related species to this taxon: ''D. ensatus'' (California giant salamander), ''D. copei'' (Cope's giant salamander), and ''D. aterrimus'' ( Idaho giant salamander). Description The coastal giant salamander can reach up to in total length as a terrestrial adult, and in paedomorphic forms, making it the largest terrestrial salamander in North America. The coastal giant salamander has stout limbs with four toes on the front feet and five toes on the back feet. The species tail is around 40 percent of the total length of the salamander and is laterally compressed. The head, back, and sides have a marbled or reticulate pattern of dark blotches on a light brown or brassy-colored background. The head is broad with a shovel-like snout and a fold of skin across the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cope's Giant Salamander
Cope's giant salamander (''Dicamptodon copei'') is a species of salamander in the family Dicamptodontidae, the Pacific giant salamanders.Behler, J. L. and F. W. King. (1979) ''National Audubon Society Field Guide to Reptiles and Amphibians'', Knopf, It is native to Washington and Oregon in the Pacific Northwest region of the United States. Description This species can attain lengths up to 19.5 centimeters. It exhibits neoteny rarely undergoing metamorphosis to the adult form, and resembles the larvae of similar salamander species. It usually becomes sexually, but not physically, mature. It is gold and brown in color. The costal grooves are inconspicuous. It has a rounded snout and the laterally compressed, fin-like tail of a typical larva. It retains its gills.Hallock, L. A. and McAllister, K. R. 2009Cope's Giant Salamander. Washington Herp Atlas. Behavior Little is known about the species' habitat requirements, but it has been found in mountain pools and streams. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
