Form, Function and Feeding: Changes in Tooth Size and Shape Associated With Ontogenetic Changes in Prey Consumption by Australian White Sharks (Carcharodon carcharias) White sharks exhibit distinct ontogenetic shifts in tooth morphology that underpin changes in diet and ecological function. Using Elliptic Fourier Analysis and traditional morphometrics, we reveal si...
