Where do Ensatina salamanders live?
Ensatinas can be found from the southwestern tip of British Columbia, Canada, down the North American coast to the top of Mexico’s Baja California Peninsula. They also live on the western slopes of the Cascade and Sierra Nevada mountain ranges (IUCN SSC Amphibian Specialist Group 2015).
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 Ensatina salamanders poisonous?
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.
How did the Ensatina salamanders spread through California?
The various Ensatina salamanders of the Pacific coast all descended from a common ancestral population. As the species spread southward from Oregon and Washington, subpopulations adapted to their local environments on either side of the San Joaquin Valley.
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.
Where is the Ensatina from?

Can salamanders see color?
The salamanders were able to discriminate blue from green, and green from red (Fig. 10). The results can be explained by assuming a trichromatic color vision based on 3 photoreceptor types maximally sensitive around 450 nm, 500 nm and 570 nm (Fig. 12).

What do you do if you find a salamander?

Ancestral salamanders likely had a complex aquatic-to-terrestrial life cycle and a basic tetrapod body form. We show that permanent simplifications to aquatic-only or terrestrial-only life cycles have resulted in accelerated rates of salamander body form evolution.
