Mitogenomic sequence and phylogenetic placement of the Hortle's whipray Himantura hortlei (Elasmobranchii: Dasyatidae)

Abstract

Chondrichthyans are a class of fishes threatened with habitat destruction and fishing pressures. The current study presents the complete mitochondrial genome sequence (17,688 bp) of the vulnerable Hortle's whipray, Himantura hortlei. The mitochondrial genome arrangement is consistent with that seen in most vertebrates, containing 13 protein-coding, 22 tRNA, 2 rRNA genes, and 1 control region. Phylogenetic analyses were performed based on mitogenome and ND2 sequences. Under our taxon sampling scheme, Himantura hortlei was found to be most closely related to H. fai.
