On a sea monster's body, there was actually nothing too economically valuable. Their meat was too tough and difficult to eat, and the rendered fat had a strong, foul, fishy stench. Only the impoverished freemen at the very bottom class would grit their teeth and buy it to eat or use it as cheap lamp oil.
Although the hides and bones of sea monsters could be used to forge defensive equipment, compared to the sea monsters' formidable strength that could capsize entire ships and crush human bones, the cost and risk of hunting them were too great; it was completely unprofitable from a business perspective.
