Colour vision in billfish

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2000
Members of the billfish family are highly visual predatory teleosts inhabiting the open ocean. Little is known about their visual abilities in detail, but past studies have indicated that these fishes were likely to be monochromats. This study, however, presents evidence of two anatomically distinct cone types in billfish.
