  abstract = {{R}ecent comparative studies of billfishes ({I}stiophoridae and {X}iphiidae) have provided evidence of differences in the form and function of the rostra (bill) among species. {H}ere, we report the discovery of a new structure, lacuna rostralis, on the rostra of sailfish {I}stiophorus platypterus, which is absent on the rostra of swordfish {X}iphias gladius, striped marlin {K}ajikia audax and blue marlin {M}akaira nigricans. {T}he lacunae rostralis are small cavities that contain teeth. {T}hey were found on the ventral rostrum surface of all {I}. platypterus specimens examined and dorsally in half of them. {V}entrally, the lacunae rostralis were most prominent in the mid-section of the rostrum. {D}orsally, they occurred closer to the tip. {T}he density of lacunae rostralis increased towards the rostrum tip but, because they are smaller in size, the percentage of rostrum coverage decreased. {T}he teeth located within the lacunae rostralis were found to be different in size, location and orientation from the previously identified micro-teeth of billfish. {W}e propose two potential functions of the lacunae rostralis that both relate to the use of the bill in feeding: mechanoreception of prey before tapping it with the bill and more efficient prey handling via the creation of suction, or physical grip.},
