The complete mitochondrial genome of the three-spot seahorse was sequenced using a polymerase chain reaction-based method. The total length of mitochondrial DNA is 16,535 bp and includes 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and a control region. The mitochondrial gene order of the three-spot seahorse also conforms to the distinctive vertebrate mitochondrial gene order. The base composition of the genome is A (32.7%), T (29.3%), C (23.4%), and G (14.6%) with an A + T-rich hallmark as that of other vertebrate mitochondrial genomes.
