Tigerfish Mermaid Picture

Hi! Once again, I must ask of you whether or not this is in the right category. I'm sorry. I put it in the "Sword and Sorcery" because mermaid are usually categorized under "myth" and mythological creatures are usually within the sword and sorcery. I hope. XD

I've seen something similar to this in a book called "Freaks!" (I forgot the author), but is was more animalistic and I think they called it part lionfish...?
