From: Skull shape reflects prey size niche in toothed whales Figure 2. Frequency graphs showing absolute prey size (log<sub>10</sub> prey size) with spline smoothing. (A) Prey size niche in raptorial feeding (n = 34, purple), suction feeding (n = 18, green) and all odontocetes (n = 52, orange dashed). (B) Prey size niche in elongate (n = 6, red) and brevirostrine (n = 6, blue) raptorial feeding taxa compared to all odontocetes (n = 52, orange dashed). Error bars depict standard error of the mean. Data are binned into 0.25 log<sub>10</sub> prey size classes. Fish and cephalopods are not separated within the analysis.
