A specific species of plankton drove the red tide that brought dramatic bioluminescent light shows to the San Diego coast in the spring of 2020.

A major red tide event occurred in waters off Southern California in the spring of 2020, resulting in dazzling displays of bioluminescence along the coast. The spectacle was caused by exceedingly high densities of Lingulodinium polyedra (L. polyedra), a plankton species renowned for its ability to emit a neon blue glow.
