Opahs are commonly known as moonfish
Opahs? I've never even heard of them.
They are fishes comprising the small family Lampridae
Hmm cool! What else do you know about them?
Only two living species occur in a single genus
Oh wow, really? That's pretty crazy!
One species is found in tropical to temperate waters of most oceans
Cool, I really want to know what they look like now.
