Material properties of the exoskeleton of Paralomis birsteini

This data set includes measurements of the percent calcium, thickness, and microhardness of the exoskeleton in Paralomis birsteini, Cancer borealis, and Callinectes sapidus. Measurements were taken in the carapace, major chela, and minor chela of each crab. Paralomis birsteini were trapped at ~1350 m depth off Marguerite Bay, western Antarctic Peninsula in 2015. Cancer borealis were trapped in the Gulf of Maine, USA at ~50 m depth, and Callinectes sapidus were trapped in Florida, USA at depths shallower than 30 m.
