Dicamptodontidae is nicknamed the Pacific Giant Salamanders after the fact that they are sorta large but not as big as the members of the family Cryptobranchidae such as the Hellbender or the Chinese Giant Salamander. They are the largest terrestrial salamanders. The Coastal Giant Salamander can reach over a foot long. They are found on the Pacific Coast of North America from California up to Canada.
As the name suggests, the Idaho Giant Salamander is primarily found in Idaho but it is also found in Montana. It can reach up to 9 inches long.
The Cope’s Giant Salamander is found in Washington and Oregon. They almost never metamorphose so they retain their gills into adulthood.
The California Giant Salamander only makes it home in the northern half of the state of California. It is listed as Near Threatened by the IUCN.
The Coastal Giant Salamander is found from California up to barely in British Columbia on the west coast.
