The chromosome-level genome sequence of a bone-eating worm, Osedax fenrisi Eilertsen, Dahlgren & Rapp, 2020 (Sabellida: Siboglinidae) and its associated microbial metagenome sequences

<ns3:p> We present a genome assembly from an individual <ns3:italic>Osedax fenrisi</ns3:italic> (bone-eating worm; Annelida; Polychaeta; Sabellida; Siboglinidae). The genome sequence has a total length of 699.06 megabases. Most of the assembly (96.07%) is scaffolded into 8 chromosomal pseudomolecules. The mitochondrial genome has also been assembled, with a length of 20.29 kilobases. Gene annotation of this assembly by Ensembl identified 12 909 protein-coding genes. From the metagenome data, we recovered 11 bins, of which four were high-quality MAGs. The genomic data will provide a foundation for studying symbiotic nutrient acquisition, bone-degradation mechanisms, and the ecological roles of bone-eating worms in deep-sea carbon and nitrogen cycling. </ns3:p>
