The chromosomal genome sequence of the giant barrel sponge, Xestospongia muta Schmidt 1870 and its associated microbial metagenome sequences

<ns3:p>We present a genome assembly from a specimen of <ns3:italic>Xestospongia muta</ns3:italic> (Caribbean barrel sponge; Porifera; Demospongiae; Haplosclerida; Petrosiidae). The genome sequence has a total length of 158.52 megabases. Most of the assembly (99.56%) is scaffolded into 15 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 18.99 kilobases in length. Several symbiotic bacterial genomes were assembled as MAGs, including <ns3:italic>Candidatus</ns3:italic> Poribacteria species, Candidatus Latescibacteria, Acidobacteriota, Actinomycetota Gemmatimonadota, multiple Chloroflexota and the archaeon Nitrosopumilus. Gene annotation of this assembly on Ensembl identified 20,220 protein-coding genes.</ns3:p>
