Those are some interesting points; especially the one about the rats. Now that I think back, didn't Lady Smith mention mice in one of her quotes? I don't think seals and dolphins would be present at the bottom of the sea. Dolphins breathe air and live in warmer climates.

I'll include most of this stuff; it's just important to note what is clearly present and what may have been present. While I believe it would be logical for Rapture to have fish or kelp farms, I don't see any evidence that there actually were any.

As for ADAM-infused plants and Sea slugs...

I guess that counts as the flora and fauna, but I want to know what the people of Rapture had accesss to in their daily life. I wonder if they'd have access to the plants and what they'd use them for...
