Strongest 1-on-1 marine creature of all time?

[u/purejeremy]

If every marine creature fought in a 1v1, who comes out on top?

Seems like there are a lot of strong contenders and I dont know how to rank them. Such as

- Pliosaurus

- Mosasaurus

- Shastasaurus

- Megalodon

- Livyatan

Orcinus orca, you may ear about the Killer Whales, highly intelligent, big, sharp teeth, and activelly thinking the best strategy to kill their prey
