The silverfish is a 31c/240 orthogonal spaceship that was constructed on May 9, 2020.[1] Various reductions brought it down to its current size of 210,108 cells,[2] making it the smallest known spaceship of this speed, surpassing the centipede caterloopillar in cell count (and, as a result, making the smallest 31c/240 spaceship true-period again).
