Eater head siamese eater tail (or eater siamese eater, or eater with nine) is a still life consisting of two eaters attached to each other. As a result it can eat gliders, too.

Three other ways of siamizing two eaters together are possible. The first two are similar 12-cell objects, while the third — elevener — is a deeper connection.


Eater head siamese eater tail is the fifty-eighth most common still life in Achim Flammenkamp's census, being less common than cis-boat on dock but more common than cis-block on long hook.[1] It is also the sixty-eighth most common object on Adam P. Goucher's Catagolue.[2]
