The complete mitochondrial genome of sponge Halichondria (Halichondria) sp. (Demospongiae, Suberitida, Halichondriidae)

摘要

In this study, we found out the complete mitochondrial genome of Halichondria (Halichondria ) sp., a common demosponge in China. This is the first complete mitochondrial report on the genus Halichondria . The mitochondrial genome of Halichondria (Halichondria ) sp. is 20 746?bp in length, with 14 protein-coding genes, two rRNA genes and 25 tRNA genes. When compared with the complete mitochondrial genome of Hymeniacidon sinapium , our phylogenetic result suggested that Halichondria (Halichondria ) sp. converged well according to morphological result.
