Bavestrello, G.; Calcinai, B.; Sarà, M. (1996). Delectona ciconiae sp. nov. (Porifera, Demospongiae) boring in the scleraxis of Corallium rubrum. Journal of the Marine Biological Association of the United Kingdom. 76 (4): 867.
A new species of sponge, belonging to the genus Delectona, has been observed in the scleraxis of Corallium rubrum from three Mediterranean banks (Alboran, Elba Island and Bosa Marina). The species, described here as Delectona ciconiae, shows a spicular complement composed of spiny rhabds, very irregular in shape and size, whose derivation from amphiasters has been suggested; toxiform centrotylote oxeas; slender, irregular amphiasters and subcircular or ovoid rough discs. The taxonomic position of this species, within the Clionidae, has been discussed.
