The first complete mitochondrial genome of Synandwakia multitentaculata (Actiniaria, Andvakiidae)

Year: 2026

Type: article

Abstract: The complete mitochondrial genome of Synandwakia multitentaculata, a marine protected species endemic to the western coast of Korea, was sequenced and analyzed. The circular mitogenome is 18,350 bp with AT-rich composition (G + C content: 34.3%) and contains 17 genes: 13 protein-coding genes (PCGs), two ribosomal RNAs , and two tRNAs. All PCGs are encoded on the heavy strand and initiate with ATG. The mitogenome shows characteristic Actiniaria split-gene architecture in COX1 and ND5, with ND1 and ND3 located within the ND5 intron. Phylogenetic analysis of 13 PCGs placed S. multitentaculata with Diadumene lineata within Metridioidea, providing the first mitochondrial genomic resource for Synandwakia and the family Andvakiidae.
