Atlantic observation of Calanus marshallae (Copepoda; Calanoida)

Atlantic observation of Calanus marshallae (Copepoda; Calanoida)

1998

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.
