The mitochondrial genome of the deep-sea glass sponge <i>Lophophysema eversa</i> (Porifera, Hexacinellida, Hyalonematidae)

<div><p></p><p>We reported a nearly complete mitochondrial genome (mitogenome) from the glass sponge <i>Lophophysema eversa</i>, the second mitogenome in the order Amphidiscosida and the ninth in the class Hexactinellida. It is 20,651 base pairs in length and contains 39 genes including 13 protein-coding genes, 2 ribosomal RNA subunit genes and 24 tRNA genes. The gene content and order of <i>L. eversa</i> are identical to those of <i>Tabachnickia</i> sp., the other species with a sequenced mitogenome in Amphidiscosida, except with two additional tRNAs and three tRNA translocations. The <i>cob</i> gene has a +1 translational frameshift. These results will contribute to a better understanding of the phylogeny of glass sponges.</p></div>
