Why striped marlin change colour when hunting

[@milktruckdriver]

Anti-camo to prevent friendly fire. Pretty cool.

[@jaybanks2709]

good analogy for something like this nice

[@complimentary_voucher]

Like the other person says, this is a plausible theory but they do all seem striped. Perhaps they all have the same level of arousal while hunting and are displaying simultaneously, but I fail to see the attacking/passive differential that would support their theory. Maybe the footage is exaggerating the striping.

Huh? They all look striped to me.
