It was 55 degrees F.around 8 PM at about 8,000 ft. elevation on a mountain pass in Alpine County when I saw this rubber boa crossing the road. It eventually dropped down a huge tree stump to get away from me and curled up under some tree bark.
As you can see in this video, when they feel threatened, Northern Rubber Boas often curl into a ball with their head hidden in the middle and the tail on the outside, elevated like a head, which it resembles. When a predator attacks what it thinks is a head, it will only injure the tail, which is much less life threatening to the snake. Many rubber boas have scars on their tails from such attacks Natalie took Chad and myself to look under a board she found in Marin County that is used as a shelter by at least 8 rubber boas. When Chad lifts it, we see 7 boas and a Coast Gartersnake.
