Are Ensatina salamanders poisonous?
Ensatina is the common name for a common lungless salamander found through much of the west coast of North America from British Columbia to northern Baja California. Ensatina have a diagnostic constriction at the base of their tail. They are able to exude a milky toxic substance from poison glands in this tail.
Where do Ensatina salamanders live?
The ensatina is a fairly common salamander. From southern British Columbia in Canada to northern Baja California in Mexico, it can be found lurking under logs in forests along the entire western coast of North America.
What do Ensatina salamanders eat?
In the wild, ensatina eat sow bugs; orthopterans; small, non-noxious millipedes; spiders; and even snails. Captive adults thrive on small crickets, small waxworms and field plankton (insects from an insecticide-free area caught in a sweep net).
Are Eschscholtzii and Klauberi the same species?
Some researchers see Ensatina eschscholtzii as two or more species that make up a superspecies complex. They recognize E. e. klauberi, found at the southern end of the ring, as a separate species – Ensatina klauberi.
What happens if you touch a salamander?
Salamanders are not dangerous to humans, they are shy and cryptic animals, and are completely harmless if they are not handled or touched. Handling any salamander and then rubbing your eyes or mucous membranes has the potential to cause irritation and discomfort.
What does the Ensatina do when threatened?
The ensatina was named for its habit of brandishing its tail like a sword. When threatened, the salamander straightens its legs to their full height, arches its back slightly, and points its tail in the air. Ensatina females lay their eggs underground or under forest debris in late spring.
What does a Ensatina eat?
Diet: Ensatina eats a wide variety of invertebrates. Behavior: Ensatina live in relatively cool moist places on land. They stay underground during hot and dry periods where they are able to tolerate considerable dehydration.
Is Ensatina a ring species?
The Ensatina eschscholtzii plethodontid salamander complex of western North America is a famous example of a ring species [5, 12–15]. These salamanders inhabit mesic, forested environments in Pacific western North America, and in California form a geographic ring around the arid Central Valley (Figure 1).
Is the splitting of the Ensatina salamanders an example of speciation?
If you’ve skimmed a high school biology textbook, you’ve probably seen the picture: multicolored salamanders meander around California, displaying subtle shifts in appearance as they circle its Central Valley. This is Ensatina eschscholtzii, and it’s so well known because it is a living example of speciation in action.
Is it safe to pick up a salamander?
Salamanders have very absorbent skin and the oils and salts from human hands can seriously harm them. This is why salamanders should never be handled, except during conservation related efforts.
Where are the Ensatina salamanders found in the world?

How big does an adult Oregon ensatina get?
Several adult Oregon Ensatinas and a tiny black juvenile which has lost its tail wish they could crawl back under their logs in Washington. An adult Ensatina measures from 1.5 – 3.2 inches long (3.8 – 8.1 cm) from snout to vent, and 3 – 6 inches (7.5 – 15.5 cm) in total length.
