Pholas orientalis (angelwing clam) is a mollusc species found in the coastal areas of Southeast Asia. Despite its economic significance, genetic information on the species is lacking. In this study, a P. orientalis specimen was collected from Kedah, Malaysia, and its complete mitochondrial genome was assembled using whole-genome sequencing data generated on an DNBSEQ-G400 platform. The circular mitochondrial genome of P. orientalis is 18,995 bp in size and contains 12 protein-coding genes (PCGs), 22 tRNAs, two rRNAs, and three control regions (D-loops). All genes are located on the heavy strand. The mitogenome has a base composition of 25.4 % A, 41.5 % T, 22.1% G, and 11 % C, exhibiting a bias towards AT content (66.9 %). The mitochondrial genomes of P. orientalis and 11 other Pholadoidea species were included in a phylogenetic analysis, which indicated that P. orientalis is closely related to Xyloredo nooi. The data reported in this study represents the first time that a Pholas mitochondrial genome has been reported. Such data will contribute to the better understanding of genetic relationships between P. orientalis and its relatives, leading to informed conservation and sustainable utilization of the species.
