The well-known fatty acids with a Δ5,9 unsaturation system were designated for a long period as demospongic acids, taking into account that they originally occurred in marine Demospongia sponges. However, such acids have also been observed in various marine sources with a large range of chain-lengths (C(16)-C(32)) and from some terrestrial plants with short acyl chains (C(18)-C(19)). Finally, t...

in this study marine sponges of inter tidal zone from hengam island persian gulf were collected by wading at low tides in eskeleh station at  locations 55˚ 53ʹ 40ʺ e & 26˚ 40ʹ 53ʺ n.for identifying identification of sponge samples, acid digestion method as a method of early detection and microtome section to identify the skeletal structure were used.all the identified sponges were from class de...

In the exploration of meiofauna associated with sponges and corals in shallows Cuba, we investigated nine species (Demospongia), wherein 26 nematode were revealed. Most specimens (50–95% all individuals) sponge samples belonged to family Desmodoridae (order Desmodorida), followed by Chromadoridae Chromadorida). A major part is constituted genus Acanthopharynx. statistical morphometric analysis ...

Abstract: This extensive review covers research published between 2010 and 2012 regarding new compounds derived from marine sponges, including 62 species from 60 genera belonging to 33 families and 13 orders of the Demospongia class (Porifera). The emphasis is on the cytotoxic activity that bioactive metabolites from sponges may have on cancer cell lines. At least 197 novel chemical structures ...
