PACIFIC GIANT SALAMANDER
Scientific Name:
Dicamptodon ensatus
Distinguishing Characteristics:
This large salamander is 7-12" long, has a massive head and is dark brown
with marbled coloration and a network of irregular spots of tan, copper,
gray or purple.
Importance in the Web of Life:
Pacific giant salamander feeds on aquatic invertebrates (stone flies, caddis
flies, may flies). It is preyed upon by fish, snakes and otters.
Cool Facts:
Salamanders are amphibians and the Pacific giant salamander is perhaps the
largest salamander in the world. The female stays with her eggs until they
hatch and her young leave-that may take as long as 200 days! The
salamander's defense system includes toxic skin secretions, a low-pitched
rattling sound and biting.
Threats:
Habitat destruction and a reduction in water quality can harm the salamander.
Where in Washington Can I See One?
Pacific giant salamanders are not easy to see. They live in damp evergreen
forests from the Pacific coast to the Cascade Mountains. Try an after-dark
expedition, shining your flashlight into a slow-moving stream or pond
bottom; that's where they feed at night. Maybe you'll get lucky!
What Can I Do to Help?
Don't trap, bother or remove Pacific giant salamanders-or any wild creatures-from their homes.
