The Complete Mitochondrial Genome Of The Chocolate Chip Sea Cucumber Isostichopus Badionotus (Echinodermata: Holothuroidea)

The chocolate chip sea cucumber, Isostichopus badionotus (Selenka 1867), is an ecologically and biomedically important species. In this study, we report the complete mitogenome sequence of the sea cucumber, I. badionotus (Echinodermata: Holothuroidea). The mitochondrial genome consisted of 16,319 bp, with 13 protein-coding genes, 22 tRNA genes, and 2 rRNA genes. The total nucleotide composition consisted of 31.61% A, 29.20% T, 23.48% C, 15.71% G, with a high A + T content of 60.81%. Phylogenetic analysis using the complete mitochondrial genome of I. badionotus is helpful in studying the evolution of beneficial adaptations to aid in bioremediation and biomedical research and development.
