The complete mitogenome of ghost jellyfish Cyanea nozakii (Cnidaria, Semaeostomeae, Cyaneidae)

Abstract

The cnidarian jellyfishes are impressive organisms to show animal mitochondrial genomic diversities. Their mitogenome structure is linear and tRNA content has one or two in numbers, which is highly different than other metazoans. In this study, a complete mitogenome of the ghost jellyfish Cyanea nozakii (Cnidaria, Semaeostomeae, Cyaneidae) was sequenced and analyzed. The mitgenome is 17,381 bp long with 38.5% A, 16.0% C, 13.9% G, and 31.6% T nucleotide distributions. In addition, phylogenetic relationship of C. nozakii in the class Scyphozoa was investigated by using mitochondrial protein coding genes. Due to results, C. nozakii was positioned in the paraphyletic order Semaeostomeae. This is the first complete mitogenome from the genus Cyanea.
