This project collects the sequencing data and assemblies generated for Cinachyrella kuekenthali, common name moon or golf ball sponge, to facilitate genome assembly and annotation as part of the Aquatic Symbiosis Genomics (ASG) Project (https://www.aquaticsymbiosisgenomics.org/) from samples supplied by the ASG Sponges-as-Symbiont Hub (https://www.aquaticsymbiosisgenomics.org/collaborators/the-genomic-basis-of-sponge-microbe-symbioses/). The data under this project are made available subject to the Tree of Life Open Data Release Policy (https://www.darwintreeoflife.org/project-resources/).
