How important is the color of a lure to a billfish, a tuna or any other large pelagic game fish?
For many fish, including everything from small bait fish to giant marlin and tuna, color vision can be hugely important.
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 part of what makes them, and other tropical fish often found in tanks and aquariums, so special.
