Characterization of the exoskeleton of the Antarctic king crab Paralomis birsteini
Abstract Ocean acidification is projected to inhibit the biogenic production of calcium carbonate skeletons in marine organisms. Antarctic waters represent a natural environment in which to examine the long‐term effects of carbonate undersaturation on calcification in marine predators. King crabs (D...
