On the shore, we met this tiny snake:
I had never seen one of these before, only the larger Common garter snake. This one was barely a foot long, and very slender. We saw it first, weaving its way along the old seaweeds at the high tide line; when it noticed us, it headed up the beach, going fast. We followed, and after a bit, it stopped running, coiled up, and threatened us. Not much of a threat, considering that it would fit in one of my hands.
However, these garter snakes do strike and have been known to bite. I'm glad I didn't try to pick it up.
The snake is named "terrestial", but is mainly aquatic, rarely found far from water, salt or fresh. And "Wandering" refers to its wide range; most of the western North American continent, sea level to high in the mountains.
