One of the allures of fishing in general, but even more so in the ocean, is that you never know what may be at the end of your line. If you fish a lot, you generally know what the target species is at any given time. Or as you are bit and fighting the fish, you may have a good idea of what’s on the other end based on the fight, or how heavy it is. Still, there are times when you bring that fish to color and are truly surprised by what you see.

It was one of those times for some anglers recently fishing off Costa Rica on the sportboat Spanish Fly. They were treated to a most unusual and breathtaking sight.

1798764_603712186382386_635711094_nOver 20 miles off Los Suenos, Costa Rica, the 43-foot custom Spanish Fly caught and released something that seemed to be new to science: a 300-pound “albino” blue marlin.

Well, guess what? It cannot be confirmed as an “albino” blue marlin. Not trying to put a damper on what has been claimed as the unicorn of the sea. No matter what science says, it’s a rare sight. The IGFA has made a statement that corrects quite a few publications and reports out there speculating on the newfound billfish as albino.

“Although common names for marlin generally focus on color (e.g., black marlin, blue marlin, white marlin, etc.) color is typically not the best feature to use in identifying billfish. Especially in this case! The shape and size of this marlin’s dorsal and pectoral fins clearly indicate that it’s a blue marlin even though it’s not blue at all. The eye color – black, rather than red or pink – also indicates that this marlin is leucistic (which is a reduction in pigmentation) rather than albino.”

Even though it has turned out to be a leucistic blue marlin, it still was a good day for science and fishing. But, it was a heck of a day to take off for Capt. Daniel Espinoza Jimenez, instead Capt. Juan Carlos Fallas Zamora ran the boat. Others aboard the Spanish Fly, mates Carlos Espinoza Jimenez and Robert Salinas along with clients Bob and Karen Weaver.
