Add to basketA new sponge species (Demospongiae: Agelasida: Agelasidae) is described from the eastern coast of Unguja Island in the Zanzibar Archipelago. Agelas sansibarica sp. n. is compared to all other Agelas species described so far. The new species differs from its congeners mainly in its three categories of verticillate spicules (acant…hostyles, acanthostrongyles, and acanthoxeas) and their sizes. Acanthostrongyles, well represented in the spicular complement, are an exclusive trait of the new species widening the morphological range of the genus. Summarizing on spicular complement and spicular morphotraits of 36 species belonging to the genus Agelas: i) 32 species show only acanthostyles from Indo-Pacific (n = 14), Atlantic (n = 17), and Mediterranean (n = 1); ii) three Indo-Pacific species show acanthostyles and acanthoxeas; iii) one species A. sansibarica sp. n. from the western Indian Ocean is characterised by the unique trait of three categories of verticillate spicules (acanthostyles, acanthostrongyles and acanthoxeas). A key for the Indo-Pacific species is supplied together with short descriptions, illustrations, and geographic range; literature on chemical bioprospecting of the genus Agelas is also provided. 31 pp., 21 figs, gr. 8.

Add to basketThis volume of the Fauna d'Italia, written completely in English, deals with the Porifera, or sponges. It presents the latest scientific findings, a comprehensive taxonomy, and gives details on the ecology of each species. Porifera è il nome scientifico con cui vengono classificati gli organismi marini animali comunemente chiama…ti 'spugne'. Presenti in tutte le zone del mondo dai Tropici al Polo, anche in acque dolci, le spugne hanno rivelato notevoli capacità in vari settori di applicazione, particolarmente in campo biomedico e cosmetico dove la richiesta supera la domanda. Attualmente, la situazione delle spugne in ambiente naturale è fortemente compromessa sia per l'eccessivo sfruttamento delle risorse sia per l'inquinamento delle acque. Proprio in questo campo e in combinazione con microrganismi selezionati, hanno rivelato proprietà non comuni nel risanamento delle acque, specialmente da agenti chimici. In questo libro, completamente in inglese, le ultime scoperte in campo scientifico e un quadro completo della tassonomia e delle condizioni ecologiche delle singole specie. Bologna. Edizione Calderini. xi + 554 pp., 16 plates with colour photos, 249 b/w photos, b/w illustrations, and b/w distribution maps, hardcover gr. 8 [16.5 x 24.5 cm] [in English].
