There are 2188 species of Cnidaria that are commonly found in the North Atlantic.

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 2188 total species, 780 of these species (35%) have COI barcodes (from this or any ocean).
  • There are a total of 9179 "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 North Atlantic region):
  • Of the 2188 total species, 0 of these species (0%) have North Atlantic-collected COI barcodes.
  • There are a total of 0 "North Atlantic-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 2188 total species in this region, 1408 species do not have any COI barcodes (from any region).
