Wiki excerpt: The San Francisco Garter Snake (Thamnophis sirtalis tetrataenia) is a slender multi-colored subspecies of the common garter snake, designated as an endangered subspecies since the year 1967. Some researchers estimate that there are only 1,000 to 2,000 adult snakes remaining. This garter snake prefers wet and marshy areas, and because of its elusive nature, it is difficult to see or capture.
