The chromosomal genome sequence of the fragile freshwater sponge, <i>Eunapius fragilis</i> (Leidy, 1851) and its associated microbial metagenome sequences

We present a genome assembly from a specimen of <i>Eunapius fragilis</i> (fragile freshwater sponge; Porifera; Demospongiae; Spongillida; Spongillidae). The genome sequence has a total length of 218.91 megabases. Most of the assembly (99.98%) is scaffolded into 23 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 28.5 kilobases in length. Gene annotation of this assembly on Ensembl identified 26,614 protein-coding genes. Additionally, eight high-quality bacterial metagenomes belonging to the <i>Bacteroidota</i> and <i>Pseudomonadota</i> phyla were assembled.
