Fig. 6. Resting tail curvature compared with tail curvature during swimming.
is the mean tail curvature over the length of the tail. (A) Silhouette of a resting individual from a dorsal view with a mean tail curvature (
) of 0.47radmm-1. (B) A midline for the individual shown in A is drawn with a tail curvature equal to the median value for tail curvature
measured during swimming (
=0.51radmm-1). The range of tail excursion during swimming is shown in gray. (C) Comparison of the tail curvatures of resting larvae with the median tail curvatures of an independent sample of swimming larvae shows the statistically indistinguishable differences in curvature between samples (N=11). The middle line in the box plot represents the median, the top and bottom edges of the box show the first quartile and error bars denote the second quartile.
