Fig.5. The effects of extracellular calcium levels on crystal formation in planulae. Planulae were exposed to calcium-free SW (0mmoll^-1; N=15), 9mmoll^-1 Ca²⁺ SW (9mmoll^-1; N=17) and 50mmoll^-1 Ca²⁺ SW (50mmoll^-1; N=10). *Significant difference compared with 9mmoll^-1 Ca²⁺ SW (for comparison of 0mmoll^-1 Ca²⁺ SW with 9mmoll^-1 Ca²⁺ SW, P<0.001; for 50mmoll^-1 Ca²⁺ SW with 9mmoll^-1 Ca²⁺ SW, P<0.05). Values given as mean ± S.E.M.
