When James Chambers and his colleagues discovered a new myxobacterium in North Wales in 2020, they noted that they’d found it near Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch, the village with the longest name in Europe.
So they named it Myxococcus llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogochensis.
