The upside-down jellyfish holobiont, Cassiopea xamachana , is a useful model system for tri-partite interactions between the cnidarian host, photosymbiont, and bacterial microbiome. While interaction host photosymbiont has been well studied, less understood of associated community. To date, microbiome wild C. remained largely uncharacterized. Thus, medusae (n=6) larvae (n=3) were collected from two sites in Florida Keys. Bacterial community composition was characterized via amplicon sequencing 16S rRNA gene V4 region. medusa dominated by members Alphaproteobacteria Gammaproteobacteria, while Planctomycetota, Actinomycetota, Bacteroidota, Bacillota also present, among others. Community consistent locations across structures (oral arm, bell, gonad). larval clustered apart beta diversity analysis presence several Pseudomonadota taxa that not present medusa, including Alteromonas Pseudoalteromonas Thalassobius genera. A isolate library encompassing much developed tested metabolic assays separate culture-dependent isolates bells, oral arms, laplets. Most characteristics correlated with sex or structure, but gelatinase production more common laplet isolates, lactose fermentation female arm isolates. Endozoicomonas genus dominant both our library, equally prevalent all sexes. Understanding component holobiont will allow us to further develop this important holobiont.
