Short summary
Some calcifiers can sustain normal shell growth under hypoxia, which may involve trade-offs against shell quality. This hypothesis was tested by measuring the shell growth and shell properties of a calcifying polychaete. Despite the adverse effect on metabolism, we found that hypoxia had limited impact on shell growth probably due to the changes in shell properties as trade-offs. This suggests that such plastic response could be fundamental for calcifiers to maintain calcification under hypoxia.
