Figure Caption

Figure 3. Fin-body coordination is abolished by peripheral vestibular lesion.

(A) Representative lateral photomicrographs, one of a larva with typical development of utricular (anterior) otoliths (top, control: wild-type or heterozygous for otogelin) and another of its sibling lacking utricular otoliths (bottom, otogelin -/-). Utricle position is encircled in red. (B) Attack angle as a function of posture change for bouts by control larvae (4767 bouts) and otogelin -/- siblings (3656 bouts). Data plotted as means of equally sized bins (gray lines) superimposed with best-fit sigmoids and their bootstrapped S.D. Marginals show cropped probability distributions, with otogelin -/- marginals superimposed on control data as dashed lines. (C) Fin-body ratio, or the maximal slope of best-fit sigmoid, plotted with 95% confidence interval. (D) Median posture change during bouts by individual clutches (gray) and their means. Pairwise t-test, t₄ = 3.13, p = 0.035. (E) Mean deviation of posture from horizontal during steep climbs (> 20°). Pairwise t-test, t₄ = 3.02, p = 0.039.
