A saltwater fish is any fish that lives in marine environments with high salinity levels, like oceans and seas. Think of them as the globe-trotting adventurers of the fish world 🐟✈️. Unlike freshwater fish, saltwater fish have adaptations to regulate their internal salt balance in a highly saline environment. Examples include tuna, salmon (for part of their lives), and cod. They are crucial to marine ecosystems and human diets. They offer a wide variety of flavors and textures.
