So, coronaviruses and influenza viruses have nonoverlapping habitats?

That's not the reason why ants don't outcompete shrimps. Does it help if I say shrimps and whales?

Yes, it is.

> Does it help if I say shrimps and whales?

No, because shrimp and whales also mostly don't compete because they have largely non overlapping habitat within the ocean (and actually are otherwise more “potentially competitive”, if you pick the right ones of each, since both many shrimp and some whales eat krill, for instance.)

This is a case where it is probably better to just make your argument directly than to rely on analogy, I suspect.
