Abstract Although several strandings of the leatherback turtle (Dermochelys coriacea Vandelli, 1761) have been reported in Korea, its haplotype or mitogenome have yet to be investigated. Herein, we report the first complete mitogenome of D. coriacea. The 16,501-bp sequenced mitogenome is similar to those of other marine turtles, and the particular genetic features reported in birds and turtles were also found in ND3 and ATP8. The comparison of the control region verified that D. coriacea stranded in Korea belonged to the haplotype JD1 (identical to haplotypes I and Dc9.1). Multigene phylogeny revealed that D. coriacea was well separated from other Cheloniidae species, and the overall tree topology was congruent with the recent phylogenetic analysis of marine turtles. These results provide information fundamental for genetic and conservation studies on leatherbacks, especially the critically endangered West Pacific Ocean subpopulation.

The leatherback sea turtle Dermochelys coriacea (Vandelli 1761) is the only extant genus of the family Dermochelyidae. It comprises seven subpopulations (Northwest Atlantic Ocean, Southeast Atlantic Ocean, Southwest Atlantic Ocean, Northeast Indian Ocean, Southwest Indian Ocean, East Pacific Ocean, and West Pacific Ocean) those are threatened by fisheries bycatch and human consumption (Wallace et al. 2011). Among those, the West Pacific Ocean (WPO) subpopulation has been listed as “Critically Endangered” by the International Union for Conservation of Nature and Natural Resources Red List of Threatened Species in 2013 (Tiwari et al. 2013). Until now, a total of six haplotypes have been reported in the WPO subpopulation (Dutton et al. 2007). The leatherbacks foraging around Japan mainly comprise the JD1 haplotype, which is identical to Haplotype I sensu Dutton et al. (1999) and originates in the WPO stock of New Guinea and the Solomon Islands (Yoshikawa et al. 2016). However, although several strandings of D. coriacea have been reported in Korea (Kim et al. 2017a),
