This critter is also called Ziphius, from the Greek word "xiphias", which means sword. It allegedly swashbuckled its way over the seas, cutting vessels open with its sword-like dorsal fin, "doing mischief" (Loki-d, anyone? Teehee).
And, before you go, please take note of the Ziphius' face expression: "Oh, crap." Seriously, Olaus, you're killing me.
