Chromosome-level genome sequences of the elephant ear sponge, Ianthella basta (Pallas, 1766), its Haplosyllis basticola worm cobiont, and associated microbial metagenome sequences
Two chromosome-level genome assemblies from a specimen of Ianthella basta and its Haplosyllis basticola and worm cobiont are presented, of which two were high-quality metagenome-assembled genomes.
