Most people won’t even catch half of these things, but when I’m given a location, or specific situation, I try to fully set design stuff. I don’t just have “fish” but specific ones to the area the scenes may take place in; as I did here in the coastal waters of New Jersey. Something else I try to do is brand everything for Cobra. They love reminding people who they are, and what the organization is… kind of like Amazon. 
Hence their branded “fins”.
