How important is the color of a lure to a billfish, a tuna, or any other large pelagic game fish?
For fish, especially those living in shallow water or staying near the surface, color vision can be hugely important for many species, including everything from small bait fish to giant marlin and tuna.
Consider mahi-mahi, almost certainly they would never have developed their outstanding coloration if they were not also gifted with color vision. This is a major part of what makes them, and all those gorgeous little tropical fish often collected and found in glass tanks and aquariums, so special.
