A snake is the cheapest way in both population and bounding box to stabilize a line of three cells, such as in [[cauldron]], and the cheapest in bounding box but not population for a line of five, such as in the [[rectifier]].

Snake is a 6-bit still life. It was discovered by the JHC group in 1970.[1]
Snake is the twenty-first most common still life in Achim Flammenkamp's census, being less common than boat-tie but slightly more common than big S.[2] It is also the twenty-eighth most common object on Adam P. Goucher's Catagolue. It is the rarest of the five 6-bit still lifes.[3]
The snake is about twice as common in C2_4 (the symmetry it has) compared to asymmetric soups.
As rock
The snake can act as a rock. An example is shown below in Conduit 1.

As induction coil
A snake is the cheapest way in both population and bounding box to stabilize a line of three cells, such as in cauldron, and the cheapest in bounding box but not population for a line of five, such as in the rectifier. Snakes are also the most efficient way to stabilize certain non-flat regions such as those in 55P10 and 28P7.2, although aircraft carriers also work for this purpose.
