The white marlin is dark blue to brown on the back and silvery white on the belly and sides. It has spots on its dorsal fin. The most noticeable characteristic is the rounded tips of its dorsal and pectoral fins. The jaw is elongated and forms a bill.
The white marlin is an offshore fish and prefers blue water. They are found in temperate and tropical waters of the Atlantic and Gulf of Mexico.
Trolling lures and natural baits are the main focus of anglers targeting white marlin, though live bait will catch them as well. They are known for their quick and erratic movement in your spread of baits. They are tricky to hook up and can make an experienced angler feel sheepish.
