Gadus is a genus of fish from the cod family(Gadidae). Their representatives live in the cold temperate and the arctic climatic zones in the northern Atlantic, in the northern Pacific and in the northern polar sea .
features
Gadus species reach a maximum length of 90 cm to two meters and have a spindle-shaped, elongated body with one to three dorsal and one to two anal fins, all of which are separated from each other. Your lower jaw is shorter than your upper jaw so that it protrudes. A goatee sits on the lower jaw . The palatine bone is toothless. The scales overlap. The pelvic fins have a single, slightly elongated filament. The sideline stands out brightly from the color of the sides of the body and extends without interruptions at least to the middle of the third dorsal fin, after a gap down to the caudal peduncle. Pores of the lateral line system are also found on the head.
