Hook with tail (or snake eater) is an 8-cell still life. It is the sixty-ninth most common still life being less common than loaf siamese loaf but more common than long integral. 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 hook with a tail. On April 29, 2007 Dean Hickerson found a 4-glider synthesis of this still life.
