It is found in shallow water in the Caribbean Sea and the Gulf of Mexico. Species Cliona annulifera. Oscules conspicuous, usually of lighter color. Adult Cliona provides shelter for other aquarium animals and makes a striking focal point. Zooxanthellae (Symbiodinium: Dinophyta), which are associated to diverse shallow-water cnidarians, also engage in symbioses with some sponge species of the genus Cliona. Some of these are probably synonymous or just representative of ecophenotypic variability. Cliona definition is - a genus (the type of the family Clionidae) of boring sponges. They are efficient excavators of calcareous materials including corals and shells. A bright yellow, corn-cob shaped sponge that exhibits pumping of water through prominent osculum. Experiments on the tolerance of two species of clionids to lowered salinities indicate that Cliona vastifica Hancock has a wider range of tolerance than Cliona celata Grant. (1995). In order to get a clearer picture of the abundance of various species of boring sponges, the total incidence and the species wise incidence in the various atolls were calculated for 5 atolls. vastifica Hancock,C. 8-9. 375-381. This site was created to honour the memory and continue the work of Dr William C. Austin, renowned scientist, researcher, natural historian, environmentalist and educator. Zootaxa 4178(4): 583–592. Species Cliona albimarginata. Cliona acephala (Porifera: Demospongiae: Clionaida), a new encrusting excavating reef sponge from the Colombian Caribbean belonging to the Cliona viridis species complex. celata, the most abundant boring sponge in the high salinity bays of the Seaside, is the least abundant species in the lower salinities of Bayside creeks.C. Filter by type Search Advanced search ... Cliona Index. However, these species have unusual aspects of their spirasters, both in dimensions as well as outline, which suggest closer proximity between the Ecuadorian species and C. euryphylle. Four species ofCliona occur on both the Seaside and the Bayside of the Eastern Shore peninsula of Virginia:C. celata Grant,C. The massive form apparently reaches its easterly limit around Dorset. Therefore it belongs to the Cliona viridis species complex, which, as a group, is widely distributed and commonly displays high bioerosion rates. The taxonomie status of different morphotypes generally ascribed to the species of boring sponge Cliona viridis is examined. In the present study we provide the first record and a description of a Mediterranean lineage of C. viridis(Schmidt, 1862) in the south-western Atlantic. Species Cliona arenosa. The sponge was found excavating only Turbinaria mesenterina colonies of … Cliona celata is widespread around the coast of Britain and Ireland although the massive form is only common around the south west coasts of Britain and lacking in the North Sea. Due to an increasing need to be able to monitor bioerosion processes it becomes important to identify common bioeroding sponges on a species level. Boring (burrowing) sponges create a canal system by chemically etching out coral or shell material for shelter and during the process simultaneously create sediment (Holmes 2000). Cliona delitrix: Cliona delitrix is a species of burrowing demosponge belonging to the family Clionaidae. lobata Hancock, andC. Plate VII, Figs. orientalis can be recognized by its spiraster morphology, i.e. In juvenile stages, the Cliona sponge hollows out a system of cavities and canals in the dead shell, removing small fragments of material with amebocytes. Dark green to brown incrustations, spread over the excavated substratum, reaching sizes up to about 1-2 m; young specimens are made of partly fused papillae. An Cliona viridis in uska species han Porifera nga syahan ginhulagway ni Schmidt hadton 1862. The sponges are the most primitive of the multi cell animals and highly successful. Accurate identification will require molecular studies and is presently deferred. Species Cliona aprica. Rosell and Uriz (2002) also accepted the possibility of Cliona species having wide distributions, for example, Cliona amplicavata Rützler, 1974 and C. celata. A review of the distribution of these two species reveals that popu lations of the former have penetrated brackish waters in several parts of the Five species, of the eight known for the genus, are here recorded. Cliona is classified under the phylum Porifera. Of these, species falling under the genus Cliona are widely distributed in the various atolls of Lakshadweep followed by those of the genus Spirastrella. In the Caribbean, zooxanthellae-bearing Cliona has recently become abundant due to global warming, overfishing, and algae abundance. It may be confused with Cliona caribbaea, which is also brown, but it is thicker (in the latter species, the excavated substratum is not usually visible through the tissue, although its relief may be evident), and has conspicuous oscules with a lighter colored collar. Also known as Cliona langae Pang, 1973. The taxonomic status of different morphotypes generally ascribed to the species of boring spongeCliona viridisis examined. P-20 BORING SPONGE, Cliona celata. Two new species of cliona (porifera, demospongiae) boring the scleraxis of corallium elatius from the western pacific. ... ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe. This species bores in the shells of mollusks and plates of barnacles, and the main portion of the sponge which is exposed consists of small yellow patches 1-3 mm wide.
