What is the top predator in the ocean besides man?

I think you need to define what you mean by top.

At the moment you're able to (and repeatedly have) trivially dispute any answer your given. But you're disputing them not on the basis that the given answer is wrong but rather on the basis that it doesn't qualify against a set of criteria that you are changing to suit your current response. that makes it impossible to answer your question in any meaningful way.

I suspect your definition for "top" is basically who would win in a fight, the answer to which is almost always whoever is in their own element.

By top I mean top of the food chain, the top predator in the Oceans. The idea is to examine all of the main contenders and determine what is the overall top oceanic predator. I can't be too restrictive, it could be the fastest, the most poisonous, the most heavily armoured, the most intelligent, or the best all rounder. I have tried to use only quality references in order to avoid trivializing the determination.

As these are all oceanic creatures they should all be in their element, unlike man going into the sea.

I am sorry that old Bluey is not the top predator as she is not even capable of attacking any of the medium to larger fish or sea mammals, and is instead prey for the faster predators with sharper teeth, like an elephant or giraffe on land. If you still think the Blue whale is the top predator, make a case for it against all the other predators in the ocean.
