The California Tonguefish is a demersal fish found in the Eastern Central Pacific, ranging from California, USA, to the Gulf of California. It typically inhabits depths between 30 and 80 meters, though it can be found as deep as 201 meters. This species prefers mud or sandy-mud bottoms, where it can blend in with its surroundings. Measuring up to 21 cm in total length, the California Tonguefish has a short and deep body shape. It lacks dorsal and anal spines, but has a high number of soft rays, with 94 to 102 dorsal soft rays and 77 to 83 anal soft rays. This flatfish is adapted to life on the sea floor, where it feeds on small fishes and invertebrates. Divers might encounter the California Tonguefish while exploring sandy or muddy areas. It is a harmless species and poses no threat to humans. The IUCN has assessed its conservation status as Least Concern.
