Cod are ugly. Flat noses and big mouthed they look like a fighter that should have retired years before.
After the film Jaws a lot of attention was paid to Great White Sharks. (The largest in the world, at that time, was caught off southern New Brunswick.) The son of the owner of Gimbles in New York, with lots of time and more money made a film called Blue Water: White Death.
(I see it was before Jaws.)
In it he searches for Great Whites .... one thing he does is buy a dead whale off S. Africa and leave it for the sharks to feast upon. A very scary and impressive scene underwater.
In another segment he is following a large Great White that comes upon some food upon the bottom. As friend shark goes to eat it .... a CODFISH emerges from its' hole and attacks the shark - the prize was its' dinner and it was not about to share with man nor beast. The shark was obviously dazzled that something other than another shark would dispute to for food.
Cod grow to a respectable size, but nothing compared to the sharks ... but the pugnacious cod actually chased away this ultimate killing machine of the oceans from its' lunch.
