Abstract
Sagitta ferox is an important group of transparent marine metazoans in marine pelagic food webs, the diversity study of S. ferox in nature ecosystem is important. In this study, we report the complete mitochondrial genome sequences of S. ferox. Its complete mtDNA sequence is 12 153 bp in length, which contains 11 protein-coding genes, 11 transfer RNA genes, and 2 ribosomal RNA genes. The composition of A, T, G, and C in mtDNA is 30.23%, 28.39%, 22.13%, and 19.25%, respectively. The percentage of A + T is 58.62%. The complete mitogenome of S. ferox could be applied in the studies of biodiversity researches, molecular systematics, and the evaluation of marine ecological environment.
