[DF] Statting a Dire Mantis Shrimp

[Stix4armz]

I came across this article on The Oatmeal yesterday about the Mantis Shrimp and immediately thought, "I would never want to face this thing in an underwater level."

I turn to you all for help statting this thing, because even just statting it realistically I don't know how to go about it. (Namely the punching as fast as a bullet)

I was thinking it'd be good to stat it as a dire mantis shrimp, anywhere from SM 0 to SM+2, that way this it would actually be a serious threat to your standard DF character.

Thanks in advance for your help!
