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

In this study, we found out the complete mitochondrial genome ofHalichondria(Halichondria) sp., a common demosponge in China. This is the first complete mitochondrial report on the genusHalichondria. The mitochondrial genome ofHalichondria(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 ofHymeniacidon sinapium, our phylogenetic result suggested thatHalichondria(Halichondria) sp. converged well according to morphological result.
