The chromosomal genome sequence of the marine leech, Branchellion lobata Moore, 1952 and its associated microbial metagenome sequences

We present a genome assembly from an individual Branchellion lobata (the marine leech; Annelida; Clitellata; Hirudinida; Piscicolidae). The genome sequence is 174.1 megabases in span. Most of the assembly is scaffolded into 17 chromosomal pseudomolecules. The mitochondrial genome has also been assembled and is 16.48 kilobases in length. The metagenome of Branchellion lobata was also assembled. Of ten binned metagenomes, three were classified as high-quality assembled genomes (MAGs).
