Neighbor-joining tree based on sequences of the COI gene of the A. tonsa (Ato) and A. lilljeborgi (Ali) samples collected during the present study. Acartia negligens (Ane) and Acartia danae (Ada) were included as the outgroups. The samples collected for molecular identification are identified as “sample”, and the number at the end of each species code is the GenBank accession number
