Thyroid hormone regulates allometric trajectories in zebrafish. A-C, Principle component (PC) scores of body shape plotted against standard length for both WT (green cross) and TH− (purple open circle) zebrafish. Percent variation explained by each PC axis is shown in the upper left corner. Developmental trajectory is shown in solid line with purple SE for WT and dashed line with green SE for TH−. For comparison between graphs, gray stripes highlight period from 6 to 6.4 SL, during which TH availability is elevated. D-F, Deformation grids showing extreme shapes along each PC. G-I, Vector plots showing shape change along each PC axis, with arrows pointing from negative to positive PC values
