Morphology and localization of symbionts in Rostanga alisae. (A) Common view of the nudibranch in the natural habitat on the sponge. (B) Histological organization, longitudinal section. (C–E) are enlarged views of the areas indicated by the corresponding arrows: (C) Bacteria (b) in the mucus layer covering the body. Bacterial clusters (bc) in the epidermis of the notum (D) and foot (E). Nuclei (nu) of epithelial cells are visible. Combination of fluorescence microscopy and Phase microscopy, DNA stained with DAPI (blue fluorescence).
