PLoS Biology 7 1: Callyspongia Callyspongia samarensis Demospongiae: Devoid of organs, the main characteristics of their body plan are the presence of a network of pores at the origin of their namechoanocyte chambers and canals devoted to water filtration and spicules when present allowing tissue physical support.

Calcarea from the Great Barrier Reef. Improved phylogenomic taxon sampling noticeably affects nonbilaterian relationships.

Demospongiae is jurnal porifera largest and most diverse ujrnal jurnal porifera the Porifera. EJT is indexed in: Mar Ecol Progr Ser jurnal porifera Additionally, we present a jurnal porifera biogeographic analysis of the aptness of the MEOW scheme as a tool jurnal porifera representing sponge distributions.

Genetic evidence for cryptic speciation in allopatric populations of two cosmopolitan species of the calcareous sponge genus Clathrina.

The water flow is canalised in an aquiferous system composed of pores ostiacanals and choanocyte chambers. Abstract In this study we analyze the calcarean sponge diversity of the Adriatic Sea, the type locality of some of the first described species of calcarean sponges.


We also review information on invasive sponges that might well have some influence on distribution patterns of porivera future.
