“…The positive relationship of sponge volume with number of taxa and abundance of associated fauna has been previously shown for A. aerophoba and A. oroides (Koukouras et al 1992), as well as for other sponge species (Gherardi et al 2001(Gherardi et al , Çinar et al 2002.…”

“…Marine caves are commonly acknowledged for their "idiosyncratic behaviour" regarding the prevailing environmental features and their sessile and motile fauna (Martí et al 2004, Bussotti et al 2006, Navarro-Barranco et al 2013. The influence of the surrounding environment on the composition of sponge-associated assemblages has been observed for temperate sublittoral rocky beds and Posidonia meadows (Koukouras et al 1996, Gherardi et al 2001. In support of this, none of the macrofaunal species found associated with the sponges A. aerophoba and A. oroides in the two caves can be considered an obligate sponge symbiont: they are either sciaphilic species finding shelter in cryptic micro-habitats, including caves, or euryoecious species dwelling in a wide range of marine habitats (Ledoyer 1965, Koukouras et al 1985, 1996.…”

“…Furthermore, massive sponges, being less common in the shallow habitat, in terms of volume and density (Idan et al, 2018;Idan, 2020), may act as a limiting factor, reducing the total endobiont richness, but also forcing the macroinvertebrates to aggregate within them. This may explain their much higher density along the shallow waters of the Israeli coast, and why the well-documented link between sponge volume and their endobiont richness and abundance (Koukouras et al, 1992(Koukouras et al, , 1996Cinar and Ergen, 1998;Gherardi et al, 2001) is not expressed there (Supplementary Table 1).…”

“…Ceratonereis costae, the second most abundant organism, and the dominant polychaete in the mesophotic zone, was often reported as an abundant and even dominant species in Mediterranean sponges (Alos et al, 1981;Koukouras et al, 1992;Ilan et al, 1994;Gherardi et al, 2001;Çinar et al, 2002. In the shallow water C. costae is replaced by L. indicus as the dominant species.…”

Macrofauna Inhabiting Massive Demosponges From Shallow and Mesophotic Habitats Along the Israeli Mediterranean Coast

Sponges have long been considered as “living hotels” due to the great diversity and abundance of other taxonomic groups often found in association with them. Sponges are the dominant components of benthic communities in the Levant Sea; and especially in the recently discovered mesophotic sponge grounds off the coast of Israel. However, almost no data exist regarding their associated macrofauna. The current study sought to identify the macrofauna associated with massive sponges along the Israeli Mediterranean coast; and to compare the role of sponges, as ecosystem engineers, or “living hotels,” in both the shallow-water and mesophotic habitats. Sixty-four massive sponge specimens, from 10 different species, were collected from shallow and mesophotic habitats by SCUBA diving and Remotely Operated Vehicle, respectively. Sponge volume was estimated, specimens were dissected, and the associated macrofauna were identified. Our results reveal that the sponges supported a diverse assemblage of associated macrofauna. A total of 61 associated taxa were found, including species reported for the first time in Israel. A clear, differentiation existed in the structure of the associated assemblage between the two habitats, which is mainly attributed to four species (two polychaetes, a crustacean, and a brittle star). The trophic composition remained stable across the two habitats. No correlation was found between sponge volume and the associated fauna community parameters. The highest richness of associated fauna was found in the mesophotic habitat, where sponge diversity is also higher. In contrast, a greater endobiont abundance and density were recorded in the shallow habitat, where massive sponges may be a limiting factor due to their lower richness and abundance. Our findings emphasize the importance of sponges as ecosystem engineers, and suggest that sponge diversity may be an important factor that contribute to benthic biodiversity in these regions.

Abstract. The variability of the reticulum pattern, ornamentation and outline of the Urocythereis populations of the la strea Bay is analysed. The results show that the shell features of the form U. distinguenda (Neviani, 1928) (= U. oblonga Brady, 1866) have to be included within the high variability range of U. margaritifera (G.W. Müller, 1894). Consequently, it is suggested that in the upper infralittoral waters of the inlet two (and not three, as stated in previous investigations) species of the genus Urocythereis presently live. A second form, displaying a relatively low variability, is described as a new species, U. ilariae sp. nov.
