Figure 5.

Ontogenetic changes in the bite force of H. colliei with respect to standard length as determined by theoretical biomechanical modelling (squares, anterior; circles, posterior) and tetanic muscle stimulation experiments (diamonds, tetanic). Both anterior and posterior theoretical bite forces scaled with positive allometry, while tetanically stimulated bite force scaled isometrically. Values of r² for associated regression equations can be found in table 1.
