Chromosome-level genome sequences of the elephant ear sponge, Ianthella basta (Pallas, 1766), its Haplosyllis basticola worm cobiont, and associated microbial metagenome sequences
We present chromosome-level genome assemblies from a specimen of Ianthella basta (Porifera; Demospongiae; Verongiida; Ianthellidae) and its Haplosyllis basticola worm cobiont (Annelida; Polychaeta; Phyllodocida; Syllidae). The I. basta assembly has a total length of 209.27 megabases, with 98.55% scaffolded into...
