The complete mitochondrial genome of the South African snoek Thyrsites atun (Euphrasén, 1791) (Perciformes, Gempylidae)

Figures & data

Figure 1. Thyrsites atun species reference image. Snoek has an elongated and strongly compressed body, it is dark blue with a paler belly. The key distinguishing feature of snoek is the single lateral line running close to the upper contour of the body below most of the first dorsal-fin base then abruptly curving ventrally.

Table 1. List of mitochondrial sequences used in phylogenetic reconstruction of the family Gempylidae (Scombriformes) to investigate the placement of Thyrsites atun among 12 other species of gempylids. Trichiurus lepturus and Benthodesmus tenuis (Scombriformes: Trichiuridae) were used as outgroups (marked by an asterisk).

Figure 2. The annotated mitochondrial genome of South African Thyrsites atun. The complete and circular mitochondrial genome is 16,494 base pairs long, it consists of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and a control region (D-loop). Arrows indicate transcription directions.

Figure 3. Phylogenetic tree depicting placement of Thyrsites atun [OP133162] within the Gempylidae family derived from a Bayesian analysis of 13 protein-coding genes. Members of Trichiuridae; Trichiurus lepturus [MK333401] and Benthodesmus tenuis [AP012522] are included as outgroups. Nodal support is indicated by Bayesian Posterior Probabilities (in red are BPP <0.95, and in black are BPP≥ 0.95).
