instead of changing "fourth smallest" to "fifth smallest", it should probably be removed as it's on the larger side now |

The centipede is a 31c/240 spaceship constructed by Chris Cain later on the same day as the shield bug.[1] It actually reuses most of shield bug's circuitry despite having a quite different shape. Its smaller size is due to a more compact front-end that was built by Cain a day earlier.
It was the smallest 31c/240 spaceship making use of the 31c/240 reaction (and therefore the smallest period-240 31c/240 spaceship) until the development of the silverfish in 2020, the leaf bug in 2024 and the water strider in 2025.
The centipede ranked second place in the Pattern of the Year 2014 competition in a belated vote held on the ConwayLife.com forums, behind the waterbear.[2]
