GaKaye is  right on, Contessa.
Monkfish is one ugly beast.  It has a huge  head/mouth, most of the body is eel-like tail.
  They are  landed on the East  Coast,  but I've heard tell that most of the catch is  airlifted to Japan and China, where it fetches  BIG money. 
You never see it in the regular  supermarkets.  If you are  really lucky, you might find it fresh at a specialty fish market, close to the landing  site.  You won't think it is "poor man's" anything if you find it.
I think I've had it in hand  just a few times over  a lot of years. It is  a lot like  lobster tail in texture and flavor, and an easy fish to handle in cooking and presentation because it doesn't  fall apart or flake. 
If/when you see it offered, don't pass it up.   YUM!
