(* I’m taking your word for the fact that fish have TLR-4.)

He's correct about that, but only because I informed him of it. Ray-finned fish typically do have TLR-4, although the pufferfish, which has a stripped-down genome, eliminated it.

Coral do not have TLR-4. They have an ancestral TLR protein that does not match any of the fish or mammal TLR subtypes. Since we've been diverging from coral for about half a billion years, that's to be expected.

You are such a liar. Here's proof: Southack informs ahayes of TLR-4 in Fish
