Shell strength and growth are correlated in zebra mussels.

<p><b>A</b>: experimental data as mean growth (measured in mm increase in the 3 shell dimensions length, height, and width) in relation to the corresponding shell strength means from the 28 experimental tanks with 16 mussels each. <b>B</b>: field data as individual growth in the first year post settlement in relation to shell strength of 556 mussels. Dashed lines denote 95% confidence intervals for the fit.
