Mollusca-Gastropoda of the Mediterranean Sea There are 667 species of Mollusca-Gastropoda that are commonly found in the Mediterranean Sea. Information on the COI barcoding* status of these species is presented in the table below.*
MODE A	*All available COI barcodes for this taxa group (collected from any ocean and/or without geo-referencing):* Of the 667 total species, 350 of these species (52%) have COI barcodes (from this or any ocean). There are a total of 9973 "any ocean" COI barcode records available for this ocean and taxa group. All available taxa group COI barcodes will be included in the Mode A downloads.
MODE B	*Regional COI barcodes for this taxa group (includes only those collected in the* Mediterranean Sea region):** Of the 667 total species, 0 of these species (0%) have Mediterranean Sea-collected COI barcodes. There are a total of 0 "Mediterranean Sea-collected" COI barcodes available for this taxa group. In the map to the right, Red Stars show sampling locations of the COI barcodes in the Mode B download.
Uncoded Species	Of the 667 total species in this region, 317 species do not have any COI barcodes (from any region).

Barcoding progress summary for the Mediterranean Sea region, out of a total of 667 possible species:
