We'd almost certainly find some way to kill them if we ever ran across any of them.
We're pretty good at accomplishing things like that.
One day, there's some space sharks swimming in a sea of liquid helium and doing deep dives to get to the smaller creatures that devour the seabed of diamonds.
The next day, we're figuring out how to use space shark squeezings in our fusion reactors.
Unless, of course, the space sharks figure out how to kill us first. They will probably try if that's useful to then.
