Would a mermaid be like human flesh up top but fish on the bottom from a BBQ perspective? Are you getting surf and turf in one meal if you were to catch one and eat it?
Personally I'd like to think that there is some sort of membrane inside that separates the human portion from the fish portion.
Like if you were starving, you could eat the fish portion and give the human half a wheelchair?
Mermaid genetics. That's what happens when you ask me to write two 100 word or more posts in a day ladies.
