Marlin or Sailfish... do you know?

Both are billfish with pointy snouts and streamline bodies built for speed. It is the dorsal fin, pectoral fin and the bill that mark the difference.

This is a Sailfish. The dorsal fin is more pronounced, looking like a sail and the pectoral fin is larger. Also the bill is shaped thin like a rapier rather than thick like a Marlin snout.
