Morphometric parameters of the sailfish and swordfish (see also Figure 1).

*The streamwise position of maximum thickness is defined as the distance from the tip of lower jaw to the location of maximum thickness, normalized by the body length.
**The fineness ratio is defined as the ratio of body length to the maximum thickness.
***The wetted area of fish (standard) contains those of the bill, body (trunk) and all the fins for the swordfish, but the first dorsal, first anal and pelvic fins are excluded for the sailfish.
****The wetted area of fish (without fins) means those of the bill, body (trunk) and caudal fin only.
