In 1965, T. citrina This class includes nearly 8,800 species. Cave environment, however, is an unusual one which may be occasionally occupied by species normally living outside the cave. The sexual and asexual phases of reproductive cycles of two sponges, Tethya citrina and T. aurantium, living sympatrically in a Mediterranean coastal lagoon (Stagnone di Marsala, NW Sicily) were studied from samples collected over an 18-mo period. Spicules preparation Spicule samples of the two Demospongiae species Suberites domuncula and Tethya aurantium were generously provided by Dr. Renato Batel (Ruder Boškovic´ Institute, Rovinj, Croatia).

"The spicule bundles of Tethya aurantium are arranged of a large number of single spicules, which are much shorter (several hundred μm), than the whole bundle (several cm). However, a closer examination of the relevant morphological characters and, in recent years, the use of molecular techniques has allowed scientists to distinguish four Tethya species in Europe. Fig. ... and an interlocking skeleton of spicules. Most of the species are marine and some are freshwater. Histologically, the body of Tethya features a well-developed fibrous cortex and a choanosome, which contains the choanocyte chambers (Sarà, 1987). Endoskeleton is composed of hexasters type of spicules. Both species are oviparous and gonochoric. The body cavity or spongoceel is lined throughout the collar cells or choanocytes. amzn_assoc_linkid = "df6e3e2dfb2223ece0caaeddeb1e4806"; There are about 8500 described living species under the phylum Porifera worldwide.
