d13C and d15N values of the Atlantic blue crab Callinectes sapidus from native ranges, including the carbon and nitrogen signatures of animal (bivalves) or vegetal (primary producers including seagrasses and weeds) prey. Data are collated from 48 papers and MSc or PhD theses published between 1987 and 2020, for a total of 90 different locations. The dataset includes the coordinates and name of locations, and taxonomic information on prey. It is the initial input of the Crustaceans workflow, the input of the "Crustaceans WoRMS Taxonomic Checker" service. The only format requirement is that the species names to be checked need to be in the first column with no special character (no “_”…) and there must be an “ID” column numbering the entries (from 1 to the total number of entries in the file) to keep track. The screen reader support is enabled.

It is an intermediate file of the Crustaceans workflow that contains the validated SIA file by identifying the native and invasive species.
