All 3 species (Black Marlin, Blue Marlin & Striped Marlin) are found here.

Black Marlin are generally the largest of the three, reaching up to 15+ feet in length, and about 1,600lbs+. They strongly resemble the Blue Marlin because, interestingly, they are actually blue in color. The main physical differences that distinguish them from Blue Marlin is that they lack the distinctive striping of the Blue Marlin, the dorsal fin is more rounded and their pectoral fins are much more rigid. Black Marlin are purportedly the fastest fish in the world (according to some estimates they can reach up to 80mph). They got their name because they turn black after they die.

Blue Marlin are slightly smaller (up to 1400 lbs) and slower (up to 60 mph) as compared to Black Marlin. However, they put up an equally spirited and exciting fight, making them just as much of a thrill to catch. They are distinguished by their less rigid pectoral fins, side stripes, more pointed dorsal fin, and the fact that they don’t turn black when dead. They are abundant in Costa Rican waters and trophy specimens are routinely found on our charts.
