I tried to find some pictures of halibut (and grouper) to illustrate my point, but none that I found showed the heads very well. So I will try to describe how these fish look.
A halibut is a big and ugly fish (but good eating). I saw some up close and personal when I visited an aquarium. Its eyes are lopsided, with one looking forward, and the other on the side of its head, causing the fish to tip to the side.
The grouper appears to have sad looking eyes and a weak jaw.
I have a lazy eye, so I can look at people with one eye, and use the other to view my surroundings. Brain surgery no doubt has exacerbated this problem. All in all, I'd say that makes me a halibut. My husband I'd say leans more toward the grouper.
I guess that makes my son a seafood platter.
