  • Of the 16 total species, 14 of these species (87%) have COI barcodes (from this or any ocean).
  • There are a total of 1473 "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 16 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
