Bar plot showing the average amount of variation in shape explained by body size in six vertebrate groups. For birds and mammals, shape was measured for skull-beak and skull-mandible, respectively. For fishes, data of shape corresponds to overall body form. Data from Bright, et al. (2016), Cooper & Purvis (2009), and Friedman et al. (2019).

To what extent has body size driven body shape disparity across fish species? Friedman et al. (2019) found that, for Indo‐Pacific shore fishes, body size accounts for a low fraction of variation, suggesting that there is a very weak relationship between body size and shape in this group.

... (2.9%) of variation in shape across the entire fish assemblage, contrasting markedly with previous results for other vertebrates: for example, 80% of variation in skull and beak shape are explained by body size in birds of prey ( Bright et al. 2016), and 34% to 46% of skull shape is explained by body size in mammals (Cooper and Purvis 2009; Fig. 1). Moreover, they found substantial variation in the effect of body size on generating shape disparity across families, ranging from 3% to 50%. Thus, the results suggest that variation in shape between fish species is decoupled from size evolution, providing the first case of a release from allometric ...
