Galapagos sharks are very sly been night spearfishing for about 30 years off and on never seen one but other divers told me they will sneak up on you and grab your catch if your not paying attention, this couple after the shark took and ate there catch it followed them hoping they would spear another fish for the shark to eat, never herd of anyone ever bitten by a Galapagos shark but if I see one I would get out of the water anyway.
