Fig. 4. Plot showing the correlation between calculated and in vivo bite
forces. Both are strongly correlated (r=0.87; P<0.01) and
the slope is not significantly different from one. Thus calculated bite forces
are a good approximation of in vivo bite forces. The white circle
represents Glossophaga soricina, a nectar eater and the gray one
Desmodus rotundus, a blood-licking bat.
