FIG. 2.

Kinematics change as fish grow, and these relationships are affected by thyroid hormone. Scatter plots show the relationships between fish size and maximum (A) gape distance, (B) gape angle, (C) cranial elevation angle, (D) jaw protrusion, and (E) hyoid depression. Measurement details in text. All WT groups shown as black dots; dashed lines show best fit lines for WT samples only. Asterisks of corresponding colors indicate that a group differs significantly from values predicted by regression (paired t test, p < 0.01).
