DNA barcoding of morid cods reveals deep divergence in the antitropical Halargyreus johnsoni but little distinction between Antimora rostrata and Antimora microlepis

Diversity of the CO1 Gene of Mitochondrial DNA in Representatives of Genus Antimora (Moridae, Gadiformes) in the World Oceans

The frequency of occurrence of the COI gene of mitochondrial DNA in the Pacific flatnose Antimora microlepis and blue antimora Antimora rostrata (Moridae, Gadiformes) was analyzed in samples collected in different areas of the World Ocean. The revealed maximum haplotype diversity of COI in the blue antimora in the North Atlantics may indicate that this species emerged in this region, from which it widely distributed in the World Ocean. The Pacific flatnose Antimora microlepis originated from Antimora rostrata. Antimora might penetrate into the North Pacific by several routes: through the Panama Strait, along the coast of Antarctica, or through the Indian Ocean along the coast of Australia.
