Cods measure from 18 to 39 inches long. They weigh from 10 to 11 pounds. They have large heads with very long dorsal fins which are divided into 2 or 3 sections. They have a fleshy barbell on their chin for touch and taste as well as finding food. They live in both northern and southern hemispheres around the colder areas. The Antarctic cod is usually light gray and lives near the surface near drift ice at the edge of a polar ice cap. The females lay from 500,000 to 5,000,000 eggs depending on their size.
