Figure 4. Postoral arm and total calcite rod length in T. gratilla larvae.
A. Mean post oral (PO) arm length and B. total length of calcite rods (TLC) of T. gratilla larvae in six treatments (3 pH ×2 temperature levels) in 35 larvae from each of 3 females (n = 3, ±SE). See Table 4 for P CO2, Ωcalcite and Ωaragonite conditions.
