Habitat

• The cod makes its home in the cold waters of Northern oceans, using a natural form of antifreeze to maintain its temperature in this harsh environment.
  
  

Significance to Humans

• Humans have fished for cod from the earliest times and today cod continues to make up 10% of the world fishing industry. In recent years, however, overfishing has threatened the cod's continued existence, according to Codfarms.com.
  
  

Diet

• Codfish have sharply pointed teeth that enable them to eat practically any kind of fish or shellfish, including herring, clams and sand eels. They also eat worms.
  
  

Size and Lifespan

• After 3 years, a cod will generally weigh about 5 pounds; it can grow to as much as 150 to 200 pounds and may live up to 15 years. A cod skull contains a pair of white "earstones" that indicate the cod's age through their growth rings.
