• Cilus gilberti (Pacific corvina): Very common on the coasts of Peru and Chile. Medium-sized, with delicate flesh, it's often used in ceviche.
• Micropogonias undulatus (Atlantic Corvina or Labrada Corvina): Common in the Gulf of Mexico and the East Coast of the U.S. Smaller size, softer texture, and mild flavor.

Habitat

The croaker primarily inhabits the eastern Atlantic, from the Bay of Biscay to South Africa, including the Mediterranean, at depths ranging from 15 to 300 m.
