Hydrothermal springs (HTSs) are unique environments characterized by the emergence of geothermally heated groundwater that often releases large amounts dissolved minerals. Despite interest in HTSs, microbial composition these sites remains largely under-explored, particularly concerning interactions between marine invertebrates and microorganisms. The shallow HTSs near west coast Sicily (Italy), with a constant temperature 31 °C throughout year, host two invertebrates: nudibranch Peltodoris atromaculata (P. atromaculata) sponge Petrosia ficiformis ficiformis). Using Next-Generation Sequencing (NGS) bacterial 16S rRNA gene marker, communities were analyzed. Microbial diversity was higher P. mantle than gut, notable differences families such as Caldilineaceae, Endozoicomonadaceae, Alteromonadaceae, Enterobacteriaceae, showing abundance variations among samples. Unique signatures, including Mycoplasmataceae, Alteromonadaceae gut Enterobacteriaceae atromaculata, also identified. These findings provide valuable insights into invertebrates, which recognized bioindicators environmental conditions.
