Hook with tail (or snake eater) is an 8-cell still life. consisting of a hook with a tail. It was for a long time the smallest still life without a well-established name; it is now a vital component of the smallest known heavyweight spaceship gun, where it acts as a rock.

Note that, despite its name, this pattern is not truly a bookend with a tail.
