[Coral-List] CO2 effects on Echinoderm development

[Eugene Shinn]

Echinoderms (sea urchins) have skeletons composed of magnesium calcite 
with is 30-times more soluable than normal calcite (ordinary limestone). 
Surprisingly, results of numerous studies designed to test the effects 
of reduced pH predicted for end of the century ocean chemistry on many 
species of echinoderms produced little to no change in their 
development. The summary of these studies can be found at
