Taxon representative adult bite forces for extant Crocodylia with respect to mean body mass and the relationship between rostral proportion and force generation.

<p>(<i>A</i>) Members of the Alligatoridae are shown in blue, and members of the Crocodylidae+Gavialidae in green. The OLS regression equation describes the strong correspondence between body mass and bite force. Extant alligators and caiman (Alligatoridae), and crocodiles (Crocodylidae) show comparable relative bite-force capacities. Note that only <i>Gavialis gangeticus</i> is a statistical (i.e. outside the 95% confidence interval) low-force outlier. (<i>B</i>) Linear regression of the size-standardized residual bite force versus rostral proportion phylogenetic independent contrasts showing the low correlation between these after accounting for phylogeny and body mass.
