The chromosomal genome sequence of the bread-crumb sponge, Halichondria panicea (Pallas, 1766) (Suberitida: Halichondriidae) and its associated microbial metagenome sequences

<ns3:p> We present a genome assembly from an individual <ns3:italic>Halichondria panicea</ns3:italic> (bread-crumb sponge; Porifera; Demospongiae; Suberitida; Halichondriidae). The genome sequence has a total length of 131.46 megabases. Most of the assembly (99.62%) is scaffolded into 17 chromosomal pseudomolecules. The mitochondrial genome has also been assembled, with a length of 19.57 kilobases. Gene annotation of this assembly by Ensembl identified 26 096 protein-coding genes. Five medium-quality bacterial bins were also recovered, of which three belonged to the main <ns3:italic>Amylibacter</ns3:italic> -related symbiont, termed <ns3:italic>Halichondribacter symbioticus</ns3:italic> . </ns3:p>
