California Corbina

Menticirrhus undulatus

California Corbina are marine fish known for their elongated, slightly compressed bodies and uniform grey coloration with some iridescence. They are part of the croaker family and are unique for lacking a swim bladder, a trait that helps them thrive in turbulent environments. Divers can identify them by the single barbel on their lower jaw, which they use to detect prey. These fish are typically found along sandy beaches and in shallow bays, ranging from the Gulf of California to Point Conception, California. They usually inhabit depths up to 20 meters, often seen in small groups or alone near the surf zone. This species feeds on a variety of small invertebrates, including crustaceans, bivalves, and small fish. They employ a distinctive feeding method by scooping up sand, filtering out edible material, and expelling the rest through their gills. Spawning occurs between June and September, with a peak in July and August. Eggs are pelagic, floating freely in the water. While California Corbina are targeted by commercial and sport fisheries, they are not currently subject to specific conservation efforts. The IUCN lists them as Data Deficient. Divers encountering this species may observe their solitary or small group behavior as they navigate the sandy bottoms in search of food.
