(User is a marine creature!)

You were swimming around looking for some prey to eat, After you somehow let a whole school of fish go and didnt even get a single fish out of that large school. You went around looking for something to eat or to steal food from another creature when you sensed loud vibrations in the water, and then when you looked at the source, there was this large, brightly painted creature (which is a boat) being attacked by serval mosasaur plus Some Spinosauruses and a couple of humans on the large boat. You had known what humans were since your always being stared at by them. You sat still in the water, deciding if you should do something.

You could hear some muffled sounds from the humans that you couldnt understand because you were in water and never understood their language.
