Complete mitochondrial genome sequence for the seahorse adulteration Hippocampus camelopardalis Bianconi 1854

Abstract

In the study, we report the complete mitochondrial genome of giraffe seahorse, Hippocampus camelopardalis Bianconi, 1854. The genome of H. camelopardalis is found to be 16,523 bp in length, containing 13 protein-coding genes (PCGs), two rRNA genes, 22 tRNA genes, and a control region (D-loop). The overall base composition of H. camelopardalis is 32.46% for A, 23.54% for C, 14.54% for G, and 29.46% for T, respectively. All PCGs use the typical initiation codon ATG, except for COX1 that uses GTG. The lengths of 12S rRNA and 16S rRNA were 939 and 1685 bp, respectively. Phylogenetic analysis results showed that H. camelopardalis is closely related to the Jayakar’s seahorse H. jayakari. The complete mitochondrial genome of Hippocampus camelopardalis provided essential and important molecular data for evolutionary analysis of genus Hippocampus.
