Yes, it's claimed that shellfish will run low on shell. So far, there's no sign of that around NZ. Shells are still really hard. Snapper and other mollusc eaters had better have very strong teeth. Even if shells do dissolve, that seems okay to me because then the shellfish will be easier to eat and eating molluscs makes our food chain better supplied. But it seems unlikely that dissolving shells will really be a problem. Given the vast history of molluscs and the fact that CO2 was well over 1000 ppm for eons, there seems unlikely to be an acidification problem unduly harmful to molluscs. Mqurice
