  • Of the 28 total species, 9 of these species (32%) have COI barcodes (from this or any ocean).
  • There are a total of 58 "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 Southern Ocean region):
  • Of the 28 total species, 0 of these species (0%) have Southern Ocean-collected COI barcodes.
  • There are a total of 0 "Southern Ocean-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 28 total species in this region, 19 species do not have any COI barcodes (from any region).
