Check out this amazing footage from a diver wearing a GoPro video camera in the Cayman Islands. This spearfisher was busy collecting lionfish when he was engaged with by a Caribbean reef shark (who seemed to be mostly interested in the lionfish). Using his spear to keep the shark at bay, the diver was lucky to swim away unscathed.

What do you think? Did the diver react appropriately by using his spear?
