Pelleted diets require crushing, which exerts higher loads, especially on posterior tooth positions, where bite forces are highest. These differences...

... of winning in battles. The fact that this also decreases the mechanical advantage is largely compensated for by elongated in-levers. As a result, high muscle forces are correlated with elevated bite forces (0.27–7.6 N; factor of 28). Despite the large difference in the forcefulness of their bite, all...

We fitted lizard adhesive performance and bite force data to the Weibull distribution and found that it closely estimated maximum performance in both cases, illustrating...

We show that male Cyclommatus metallifer stag beetles bite three times as forcefully as females. This is not entirely...

The sex specificity of this trade-off suggests that the sexes differ in their optimal strategies for dealing with the conflicting requirements of bite force and sprint speed. Unlike males...

Bite force measurements show Rhagodes ( N =11) to be a much stronger biter than Galeodes ( N =8), in terms of both absolute maximum force ( Rhagodes 5.63 N, Galeodes 2.12 N) and force relative to cheliceral size. Synchrotron microtomographs of one specimen for each species reveal large...
