Highlights • Coastal habitats with the steepest ocean acidification gradients are most detrimental for larval Dungeness crabs. • Severe carapace dissolution was observed in larval Dungeness crabs along the US west coast. • Mechanoreceptors with important sensory and behavioral functions were destabilized. • Dissolution is negatively related to the growth,

Transcriptomic response to decreased pH in adult, larval and juvenile red king crab, Paralithodes camtschaticus, and interactive effects of pH and temperature on juveniles
Ocean warming and acidification are expected to influence the biology of the ecologically and economically important red king crab, Paralithodes camtschaticus. We investigated transcriptome responses of adult, larval and juvenile red king crab to assess sensitivity to reduced pH and elevated temperature. In adults, gill tissue (but not heart or
