Porifeda new species of Cladorhiza Porifera: The most recent summary of the Porifera classification [9] recognized 15 ordinal groups, one of which was recently transferred to the class Homoscleromorpha see below. Molecular phylogeny of glass sponges Porifera, Hexactinellida: We also review information on invasive sponges that might well have some influence on distribution patterns of porivera future.

Genus File Jurnal porifera part B and family File S2 part C patterns are similar, although the differences jjurnal the family diversity jurnal porifera circumglobal tropical areas and the Mediterranean and Lusitanian provinces are minimal.

Westinga E, Hoetjes P. The monophyly of Homoscleromorpha has been accepted for many years now [67] — [69]and it was assigned to the rank of a subclass of Demospongiae [69][1]. Homoscleromorpha is the smallest class of Porifera with two families, 7 genera and 87 species described so far: Calcaronea possess inequiangular triactines Fig.

An introductory overview of the four classes of the Porifera is followed by a porifrea of the structure of our main source of data for this paper, the WPD.

However, calcareous sponges are repeatedly collected from bathyal and abyssal zones in the North Atlantic as well as in the Southern Ocean [92]. Vacelet J, Boury-Esnault N. Accessed Nov 4.

We also mapped for the first time the species richness of a comprehensive set of marine ecoregions of the world, data also extracted from the WPD.

They were all found in the deep sea, including the depth record for sponges, with a species known from m.

Nowadays, use of bath sponges is limited to specialized industries and as a curiosity for tourists [34]. Iconic hexactinellids include the venus flower basket Euplectella aspergillumwhich often encloses a pair of shrimps inside its body jurnxl was used as a bridal gift in ancient Japan, and Monorhaphis chuniwhich anchors its body in the soft deep-sea floor with a single giant up to 3 m long spicule.

Regional data systems and online identification tools Progress of knowledge of global sponge diversity is generated predominantly in many regional efforts, most pre-eminently in the Australian region Fig.

Homoscleromorpha are generally located in shallow waters, but some species have been found below m [66]. Congruence between the molecular results and the current classification [87] is not apparent at lower taxonomic levels [88][96][98] — []necessitating a thorough revision through an integrative approach.

Global Diversity of Sponges (Porifera)

Specific groups have an essential function in binding unconsolidated substrate such as coral rubble and pebbles into stable surfaces. In most textbooks calcareous sponges are regarded as exclusively shallow-water organisms.

Accessed August Knowledge of living calcareous sponges is fragmentary: New techniques and increased efforts may well accelerate species discovery beyond that.

Comprehensive analyses of distribution patterns have been made previously only for the classes Demospongiae [] and Hexactinellida []based on global distributions of all taxa of these classes.
