Mahi Mahi are easily my favorite fish I've ever caught on the fly. They are the perfect exciting fight without going overboard with long, drawn out, bulldog type slogs. Just speed, aerials, bad assery, and tacos.
Specifically, a peacock razorfish = Iniistius pavo. It is found throughout the Indo-Pacific. It is interesting that this species appears to be better known in Hawaii by its Japanese name = nabeta, rather than its Hawaiian name = lae nihi.
In the Tidal Planet episode of the Blue Planet series, bottlenose dolphins echolocate the buried razorfish (probably via resonance against the swim bladder of the razorfish) and dig them out of the sand.
You just fry them up crispy skin and scales tastes like fried lobster with fried chicken skin.
Only thing, be careful taking them off the hook. They can turn their heads and take a dime sized chunk out of your hand.
