Atlantic Sailfish Istiophorus albicans
Like swordfish and marlin, the Atlantic sailfish has its upper jaw extended into a long spear. This is used to slash through shoals of fish, stunning and maiming them. It has a huge sail-like dorsal fin, which is used in displays, but is folded away for fast swimming. A similar sailfish occurs in the Pacific and may be the same species.
