Abstract Cnidarians, such as corals and sea anemones, associate with a wide range of bacteria that have essential functions, including nutrient cycling the production antimicrobial compounds. Within cnidarians, can colonize all microhabitats tissues. Among them are obligate intracellular phylum Chlamydiota (chlamydiae) whose impact on cnidarian hosts holobionts, especially corals, remain unknown. Here, we conducted meta-analysis previously published 16S rRNA gene metabarcoding data from cnidarians (e.g. coral, jellyfish, anemones), eight metagenome-assembled genomes (MAGs) coral-associated chlamydiae, one MAG jellyfish-associated chlamydiae to decipher their diversity functional potential. While dataset showed an enormous cnidarian-associated six out nine MAGs were affiliated Simkaniaceae family. The other three assigned Parasimkaniaceae, Rhabdochlamydiaceae, Anoxychlamydiaceae, respectively. All lacked genes necessary for independent existence, lacking any nucleotide or vitamin most amino acid biosynthesis pathways. Hallmark chlamydial genes, type III secretion system, transporters, host interaction, encoded in MAGs. Together these observations suggest lifestyle chlamydiae. No unique found suggesting lack specificity. Additional studies needed understand how interact coral host, microbes holobionts. This first study potential improves our understanding both microbiome range.
