General Description. Tethya aurantium generally inhabits areas that are more exposed to light and current in depths of 1–40 m, while T. citrina prefers more sheltered places and possesses a thinner cortex than T. aurantium (Sará, 1987).

De petite papille émoussées lui donnent une ressemblance extraordinaire avec une orange par sa taille et par sa surface. Sexual and asexual reproduction in two species of Tethya (Porifera: Demospongiae) from a Mediterranean coastal lagoon. A common species on horizontal or sloping rocky surfces in clean water but tolerant of silt. A total of 92 specimens of T. aurantium and 74 of T. citrina were collected from the Adriatic Sea (Palese, Bari; N 41°09’ 39” E 16°45’ 50”), on rocky bottom, around 2 meters of depth, from February to March 2010. The budding process has been studied in two congeneric Mediterranean species belonging to Tethya from different sampling sites: Marsala and Venice Lagoons (Tethya citrina); Marsala Lagoon and Porto Cesareo Basin (Tethya aurantium). Reproduction: Stalked buds produced between July and September. Both species are oviparous and gonochoric. Description of oogenesis, spawning beginning of August, segmentation, larva, metamorphosis Lévi (1956) pp. Taxonomic classification to order, family, genus and species level is based mainly on skeletal structure and composition, but increasingly on non-skeletal characters such as mode of reproduction, cellular characters, larval morphology etc. Biol Bull mar biol Lab, Woods Hole 158: 271–282, Battershill CN, Bergquist PA (1990) The influence of storms on asexual reproduction, recruitment, and survivorship of sponges.
