Calcareous red algae are foundation species and ecosystem engineers with a global distribution. The principles governing their calcification pathways are still debated and the morphological characters are frequently unreliable for species segregation, as shown by molecular genetics. The recent description of the new species Lithophyllum pseudoracemus, previously undetected and morphologically confused with Lithophyllum racemus, offered a challenging opportunity to test the effectiveness of microanatomy and ultrastructural calcification traits as tools for the identification of these two species, for integrative taxonomy.

- Hyperspectral imagers allow for detailed spectral imaging, helping classify various habitats and objects, and a new underwater system has been developed for studying the seafloor.
- The project tested this underwater hyperspectral imager in the Southern Adriatic Sea at two specific habitats: cold-water coral and Coralligenous environments.
- Initial results show promise for using this technology in mapping and monitoring underwater habitats, achieving reliable classifications despite some technical challenges.
