I love how the guy sees this shark big enough to swallow him whole, and he just kinda listlessly raises his handcannon and fires.
In the Warhammer world having your ship devoured by a skyscraper sized shark is not an uncommon occurrence. I'd wager this guy is totally bored by it. "Doesn't even have wings or tentacles. Lame."
He has high morale and good resistance (perhaps immunity) to being terrorized. Kinda like those 10 peasants in Total War that are being fired by 20 cannon and yet they don't even flinch or even think about taking cover.
