Cod is the common name for the genus Gadus, belonging to the family Gadidae, and is also used in the common name for various other fishes. Cod is a popular food with a mild flavor, low fat content and a dense, flaky white flesh. Cod’s soft liver can be tinned and eaten. Cod livers are processed to make cod liver oil, an important source of Vitamin A, Vitamin D, Vitamin E and omega-3 fatty acids (EPA and DHA). Larger cod caught during spawning are sometimes called skrei. Young Atlantic cod or haddock prepared in strips for cooking is called scrod.

The Atlantic cod, which can change color at certain water depths, has two distinct color phases: grey-green and reddish brown. Its average weight is 5–12 kilograms (11–26 lb), but specimens weighing up to 100 kilograms (220 lb) have been recorded. Cod feed on molluscs, crabs, starfish, worms, squid, and small fish. Some migrate to warm water in winter to spawn. A large female lays up to five million eggs in midocean, a very small number of which survive.
Cod meat is moist and flaky when cooked and is white in color. In the United Kingdom, Atlantic cod is one of the most common ingredients in fish and chips, along with haddock and plaice. It is also frequently consumed in Portugal and Spain

Periodically a cod with a deformed skull is found; the skull has a distinct top or crown giving it the name “king cod” or kongetorsk in Norwegian. In Norway this rare fish was earlier considered to be able to forecast the weather and was commonly used for that purpose. A woolen thread suspended the fish from the ceiling; its nose would point in a different direction depending on the coming weather. In reality, the thread rather than the fish that caused the movement. The twisted thread served as a primitive hygrometer by reacting to the air’s humidity, turning the fish as the humidity rose and fell.
