Cod (Bacalao): evolution, habitats, species—and a thousand ways to win your palate
El bacalao y sus mil formas de conquistar tu paladar — science, history, and flavor in one place.
Cod—known as bacalao in Spanish—is a cold‑water white fish that has shaped marine ecosystems, global trade, and culinary traditions for centuries. This guide explores where cod lives, how it evolved, the differences among major species, and the many ways it can delight your palate—from salted cod stews to crisp fish and chips.
Where cod lives and how it evolved
Cod belongs to the genus Gadus, thriving in cold, nutrient‑rich waters of the North Atlantic and North Pacific. Over time, cod developed a barbel (a small chin whisker) for sensing prey on the seafloor, a streamlined body for energy‑efficient swimming, and schooling behavior that improves survival and feeding success.
Habitats
- North Atlantic shelves: Iceland, Norway, Barents Sea, Grand Banks.
- North Pacific shelves: Bering Sea, Gulf of Alaska, Sea of Okhotsk.
- Depth range: typically 50–300 m; migrates seasonally following temperature and prey.
Evolutionary adaptations
- Cold tolerance: enzymes and metabolism tuned for frigid waters.
- Sensory foraging: lateral line + barbel to detect crustaceans and small fish.
- Flexible diet: shrimp, crabs, sand eels, herring—supporting wide distribution.
