<i>Macoma balthica</i>: Ocean acidification effects on larval development.

<p>Shell length, survival and development stage of larvae between day 3 and day 19 of development reared at three seawater pH conditions: ∼pH_8.1 (circles, solid line), ∼pH_7.8 (squares, dashed line), and ∼pH_7.5 (triangles, dotted line). Regression lines in (a) and (b) indicate average larval growth rate (µm.d⁻¹) and mortality rate (d⁻¹) for each treatment.
