Form, Function and Feeding: Changes in Tooth Size and Shape Associated With Ontogenetic Changes in Prey Consumption by Australian White Sharks (<i>Carcharodon carcharias</i>). [PDF]

open access: yesEcol Evol
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 significant variation in dentition across jaw position and developmental stage, with a major transition occurring at 210 cm PCL and at the sixth tooth within
