The defensive spines on the caudal peduncles of the aptly named
surgeonfishes (Acanthuridae) are capable of making incisions with almost
"scalpel-like" efficiency. The spines are also shaped much like a
scalpel in that they are not serrated but have the cutting edge on the
convex side.

Just a note from the marine end of things.
