Despite their ecological significance and biotechnological potential, freshwater sponges remain relatively understudied compared to their marine counterparts. In special, the prokaryotic communities of species from isolated yet highly diverse ecosystems, such as the Amazon Rainforest, remain unknown, leaving an important part of the Porifera microbiome underexplored. Using high-throughput sequencing of the 16S rRNA gene, we unraveled the structure of the microbiota associated to the freshwater sponges Heteromeyenia cristalina and Metania reticulata for the first time. Their microbiome was compared with that of the haplosclerid marine sponges Amphimedon viridis and Haliclona melana; and the tetractinellid Cinachyrella alloclada. Our findings reveal not only a shared core microbiome between the freshwater and marine environments but also indicate functional redundancy in their communities, suggesting that certain microbial metabolic functions are conserved across diverse habitats. Comparisons between ecosystems also revealed that microbiomes of freshwater sponges can be richer and more diverse than those of marine species. Moreover, we compared the microbiome of adults and asexual reproduction structures (buds and gemmules) of sponges from both habitats, revealing a remarkable similarity between adults and their respective offsprings, indicating an important role of vertical transmission in this mode of reproduction. Our observations emphasize the dynamic interactions and the adaptability of the sponge-associated microbiota, providing insights into how these symbiotic associations were affected during the colonization of freshwater environments and shedding light into how symbiotic relationships are maintained throughout generations.
