The scaffold-level genome sequence of an encrusting sponge, <i>Halisarca caerulea</i> Vacelet & Donadey, 1987, and its associated microbial metagenome sequences

We present a scaffold-level genome assembly from a <i>Halisarca caerulea</i> specimen (encrusting sponge; Porifera; Demospongiae; Chondrillida; Halisarcidae). The genome sequence is 195.70 megabases in span. The mitochondrial genome has also been assembled and is 19.15 kilobases in length. Gene annotation of this assembly on Ensembl identified 26,722 protein-coding genes. The metagenome of the specimen was also assembled and four binned bacterial genomes related to the relevant sponge symbiont clades Alphaproteobacteria bacterium GM7ARS4 and Gammaproteobacteria bacterium <i>AqS2</i> ((Tethybacterales) were identified.
