We just learned about the Ring Necked Snake.
Another type of snake is the Pacific Gopher Snake.
This snake is not venomous, but it sometimes pretends to shake like a rattle snake, and can shake the grass to make the same noise.
Sometimes two snakes will fight for over an hour, twisting around each other like wrestlers.
