Directed by: Guillermo del Toro

Continuity mistake: When Hellboy has been speared in the chest and fallen to the ground, the POV shot of Nuala and Nuada has been turned so their heads are at the right hand side of the frame - from Hellboy's point of view their heads should be to the left.
Continuity mistake: In the first Hellboy movie, when they first show the BPRD headquarters, it reads "Newark, New Jersey". In Hellboy II, they show what is clearly the same highly distinctive building, but it now reads "Trenton, New Jersey".
Trivia: During the auction scene, there's a man with a dog on his lap. This man is Santiago Segura, a Spanish actor. He was the underground train driver in the first film (the one who knocked HB down the train with a fire extinguisher).
Chosen answer: Why not wear it? It's clearly something that's useful to him, even if it's apparently not particularly essential. It may simply just make him more comfortable, like a human wearing a scarf in cold weather - allowing him to breathe the water that he prefers rather than air. There's never any mention that Abe can only survive for a limited time out of the water; equally, there's no suggestion that he's particularly vulnerable to atmospheric microbes. It's part of his equipment that he uses when he wishes to, that's all.
