Technical Note


The Pacific white-sided dolphin (Lagenorhynchus obliquidens Gill, 1865) is one of the most abundant, widely distributed delphinids in the North Pacific Ocean, whose existence is threatened by fisheries and environmental contamination. Herein, we report the first complete mitochondrial genome of L. obliquidens. The 16,392-bp sequenced genome exhibited typical cetacean mitochondrial gene arrangement, consisted of the typical set of 37 genes, one replication origin, and a D-loop. As expected, the genome displayed the highest similarity with that of Cephalorhynchus heavisidii and was distinct from that of L. albirostris. Multigene phylogeny also revealed that L. obliquidens was closely related to C. heavisidii, thus suggesting that the genus Lagenorhynchus is polyphyletic, in accordance with the results of recent molecular phylogenetic studies. The results provide information fundamental for genetic and conservation studies for L. obliquidens.
