The complete mitochondrial genome of the critically endangered Atlantic humpback dolphin, Sousa teuszii (Kükenthal, 1892)

Abstract

The Atlantic humpback dolphin remains an understudied, critically endangered cetacean species. Here, we describe the first complete mitogenome of Sousa teuszii, derived from an animal stranded on Île des Oiseaux, Sine Saloum, Senegal. The S. teuszii mitogenome is composed of 16,384 base pairs and is 98.1% identical to its closest relative with a mitogenome, Sousa chinensis. Phylogenetic analysis confirms its placement with S. chinensis, as well as the placement of the genus Sousa within subfamily Delphininae.
