The complete mitochondrial genome of the big-belly seahorse, Hippocampus abdominalis (Lesson 1827)

Abstract

In this study, the complete mitogenome sequence of the big-belly seahorse, Hippocampus abdominalis (Lesson, 1827) (Syngnathiformes: Syngnathidae), has been sequenced by the next-generation sequencing method. The assembled mitogenome is 16 521 bp in length which includes 13 protein-coding genes, 22 transfer RNAs, and 2 ribosomal RNAs genes. The overall base composition of the seahorse is 31.1% for A, 23.6% for C, 16.0% for G, 29.3% for T and shows 87% identities similar to tiger tail seahorse, Hippocampus comes. The complete mitogenome of the big-belly seahorse provides essential and important DNA molecular data for further phylogeography and evolutionary analysis for seahorse family.
