Chordata-Cephalochordata of the North Atlantic There are 8 species of Chordata-Cephalochordata 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 8 total species, 4 of these species (50%) have COI barcodes (from this or any ocean). There are a total of 151 "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 8 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 8 total species in this region, 4 species do not have any COI barcodes (from any region).
