Abstract: Do billfish and tuna distinguishcolours? This question has capti-vated both fishermen and scientistsfor years. Proving colour vision inthis group of fish is particularly dif-ficult since behavioural colour dis-crimination experiments—the“final proof” of colour vision abili-ty in any animal—are impossible toundertake with such large openocean fish. Instead, scientists have aimed to establish if billfish andtuna have the necessary ‘hardware’ in their eyes to discriminatecolours.More than 20 years ago two different approaches (pigmentextraction by Munz and McFarland 1977 and electrophysiologicalrecordings, Tamura et al. 1972, and Kawamura et al., 1981) wereused to try to identify the potential for colour vision in billfish andtuna. Neither technique produced any evidence of potential
