We present the first mitogenome sequence of the Smoothnose Wedgefish, Rhynchobatus laevis obtained through field sequencing on the MinION handheld sequencer. The mitochondrial genome of R. laevis is 16,560 bp in length and consisted of 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes, and a non-coding control region (D-loop). GC content was at 40.1%. The control region was 867 bp in length. Whole mitochondrial genome sequence of R. laevis will enable improved understanding of distribution, abundance, catch and trade rates of the Critically Endangered species.
