An observation of Calanus marshallae Frost, 1974, on the Atlantic side of the Polar Ocean is reported. Copepods were identified by comparing nucleotide sequences of mitochondrial 16S ribosomal RNA with a previously reported sequence from the Pacific region. Presence of the species in the Barents Sea may explain multi-modal length distributions previously obtained in the region. Potential implications for future identification of Calanus spp, in this region are discussed.
