Amphibians & Reptiles of the Dungeness Watershed

Amphibians

Amphibians have smooth and moist skin with many glands. They breathe using gills, lungs, through their skin and throat, separately or together. Their eggs have a jelly-like covering, but no shell. Six species of salamanders and newts, and five species of toads and frogs may be found in the Dungeness watershed.


Salamanders

Salamanders live their early lives in water and their adulthood on land. Others, such as lungless salamanders, live only on land.  Newts start out in the water, then spend several years on land before returning to the water for their adulthood.
