Leuresthes tenuis, the California grunion, is a species of ray-finned fish native to the Pacific coast of North America from Monterey Bay in California to Baja California. This species grows to 19 cm (7 in) in total length and is of minor importance to local fisheries, particularly during grunion runs in which the fish beach themselves to lay their eggs and are easily taken.
