Spider is an orthogonal c/5 spaceship that was discovered by David Bell in April 1997. It is the smallest known c/5 orthogonal spaceship. Its side sparks have proven to be very useful in constructing puffers and rakes. On March 7, 2019, forum user 'Extrementhusiast' completed the first known synthesis of spider (and thus the first synthesis of any c/5 orthogonal) using a mere 601 gliders.
