Very long snake is an 8-cell still life and is the long long extension of the snake which can be used as a one-time reflector. It was found in 1971.[1]

This still life can be interpreted as two mutually stabilising hooks. An alternate arrangement, which could be seen as the cis version of the very long snake, results in the canoe.

Very long snake is the sixtieth most common still life in Achim Flammenkamp's census, being less common than cis-block on long bookend but more common than tub with nine.[2]

It is the 61st most common still life on Adam P. Goucher's Catagolue, being less common than cis-block on long bookend but more common than boat with long tail. It is the 2nd rarest still life with 8 cells, being less common than canoe but more common than hook with tail.[3]


All strict still lifes with a population of 21 or fewer cells, as well as all oscillators and spaceships with 16 or fewer cells, are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
