Bacterial symbionts as an additional cytological marker for identification of sponges without a skeleton. Table 3 Accepted described species numbers N spp. The most diverse region is the Neotropical region with more than 65 species, closely followed by the Palaearctic regions with around 60 species.
Homoscleromorpha were only recently separated from Demospongiae  and like Calcarea show few classical differentiating features.
Table 2 Described species numbers of the four Porifera classes and total number of Porifera species extracted from the World Porifera Database available: Geographic entries The WoRMS database architecture provides various geographic resources which can be linked to the taxon entries.
Field Content taxon name e. Interestingly, such distribution patterns are not predicted by the hierarchical system  of MEOWs, Provinces and Realms: CO1 barcoding reveals new clades and radiation patterns of Indo-Pacific sponges of the family Irciniidae Demospongiae: Biodiversity of marine fauna on the Central West Coast.
Global Diversity of Sponges (Porifera)
The sponges of California. These were derived from an escalated collecting effort over the past two decades driven mainly by a relatively small number of factors. Molecular poriefra analyses in progress are attempting to resolve this problem.
Hajdu E, Vacelet J. Especially potifera Hexasterophora display an astonishing diversity of spicule forms and skeletal arrangements, and this for sponges unusual richness of characters poriera facilitates the delineation of natural taxa. Support Center Support Center. The Homoscleromorpha comprise a small group of marine Porifera with unique features: Accessed Aug Most of the species are white or cream, but some species may be also red, yellow or pink Fig.
The orders Astrophorida and Spirophorida form a monophyletic group for which the previously employed taxon Tetractinellida can be revived.
Invasive species As in many other marine groups, there are several cases of sponge species known or suspected to have crossed oceanic or terrestrial barriers and showing disjunct distributions.
The Indonesian sponge fauna: Revision of the genus Clathrina Porifera, Calcarea. Increased interest in these sponges, due to the discovery that they are carnivorous, and due to the development of manned submersibles and ROVs, has shown that this diversity was largely underestimated.
Esponjas marinhas da Bahia: The well-known bath sponges family Spongiidae, Fig. Calcareous sponges are relatively small, measured in mm or a few cm, however in especially rich temperate estuaries Sycon ciliatum can reach more than 50 cm in length and 3 cm in diameter .
Australian biodiversity via its plants and marine organisms.
Diversity and evolution of deep-sea carnivorous sponges. Scanning electron micrographs of microscleres courtesy of H.
Some authors  —  propose to use the name Calcispongiae for the Recent representatives to distinguish them from the exclusively fossil Heteractinida with polyactine spicules. Demospongiae is jurnal porifera largest and most diverse class jurnal porifera the Porifera. Muricy  emphasized the benefit of inclusion of histological and cytological characters in the taxonomy of other spiculate homoscleromorphs such as PlakortisPlakinastrellaPlacinolophaand Corticium.
We provide some examples of distinct generic distribution patterns, which were already observed in  and later studies. The Sponge Barcoding Project www. Atlas of Marine Invertebrate Larvae. We also review information on invasive sponges that might well have some influence on distribution patterns of the future. Perhaps not surprisingly, these distributions appear to show a strong bias towards collection and taxonomy efforts.
Taxonomic and distribution data were extracted from the online World Porifera Database  accessed Sept 30and supplemented with a survey of the literature on sponge diversity.
From the s onward, European Halichondria species, especially H.
NZ Oceanogr Inst Mem. Supporting Information File S1 Map showing numbers of sponge species and higher taxa found in each of 12 Marine Realms [ 30 ]extracted from the World Porifera Database available: Hexactinellida distributions File S4 part B for Realms and File S5 part B for MEOWs look surprisingly commonplace, with highest numbers in porifer West Pacific, porfiera the maps are deceitful by not revealing the predominantly bathyal and abyssal occurrence of these sponges.
Quinn RJ, Camp D. Recent developments from molecular phylogenetic studies Phylogenomics has recently suggested solutions for decades of differing class-level hypotheses on poriferan phylogeny by showing that sponges are monophyletic, and that classes Demospongiae and Hexactinellida form a sister group to classes Calcarea and Homoscleromorpha .
JURNAL PORIFERA EBOOK
However, calcareous sponges are repeatedly collected jurnal porifera bathyal and abyssal zones in the North Atlantic as well as in the Southern Ocean . The Australian haplosclerid Amphimedon queenslandica Fig. Do sponges help hold coral reefs together?
It is not uncommon to discover undescribed sponges in collections that have been preserved for a hundred years or more. Microscleres are frequently more common in the outer regions of the sponges and often surround aquiferous canals. Pacific coral reefs may also harbor several larger species such as Leucetta avocado and Pericharax heteroraphiswhich may reach 20 cm in height.
Sponges come in various shapes and sizes, from flat cushions to elaborate branching or cup-shaped forms, from tiny crusts measured in mm, to giant shapes in meters. Phylogeny and evolution of calcareous sponges.
As explained above, higher taxa are under enhanced investigation using molecular sequence data.
