First records of Asbestopluma hypogea Vacelet and Boury-Esnault, 1996 (Porifera, Demospongiae Cladorhizidae) on seamounts and in bathyal settings of the Mediterranean Sea

چکیده
The carnivorous sponge Asbestopluma hypogea, was known only from shallow submarine caves (-15 to -26 m) in the Western Mediterranean Sea and the Adriatic. Herein A. hypogea is reported from outside of caves, on seamounts in the Alboran Sea (-167 m), off the Balearics (-100 m) and north off Sicily (-660 m), and along steep bathyal escarpments in the Strait of Sicily (~700 m). These deeper ROV-based findings of A. hypogea are conform to the typical deep-sea occurrence of the Cladorhizidae.

Four new species of Cladorhizidae (Porifera, Demospongiae, Poecilosclerida) from the Northeast Pacific.
Interest in cladorhizid sponges has grown rapidly in the past 19 years since a unique feeding strategy, carnivory, was described by Vacelet and Boury-Esnault in 1995. Since that time, 31% of the 133 extant cladorhizids have been described. Previously, seven species of cladorhizid sponges were known from the Northeast Pacific. Here we describe four additional species, including two species of As...
متن کاملFirst insights into the microbiome of a carnivorous sponge.
Using 454 pyrosequencing, we characterized for the first time the associated microbial community of the deep-sea carnivorous Demosponge Asbestopluma hypogea (Cladorhizidae). Targeting the 16S rRNA gene V3 and V6 hypervariable regions, we compared the diversity and composition of associated microbes of two individual sponges of A. hypogea freshly collected in the cave with surrounding seawater a...
متن کاملA new species of Abyssocladia (Porifera, Demospongiae, Poecilosclerida, Cladorhizidae) and other carnivorous sponges from the far eastern Solomon Islands.
Two species, one each of Abyssocladia Lévi, 1964, and Asbestopluma Topsent, 1901, are recorded from the far eastern Solomon Islands for the first time. Abyssocladia lakwollii sp. nov. is characterized by the pedunculate disc-shape of the body, the unusually large size of the isochelae I microscleres, and by the shape of the cleistochelae with crossed central teeth. Asbestopluma (A.) desmophora ...
متن کاملTwo new species of Chondrocladia (Demospongiae: Cladorhizidae) with a new spicule type from the deep south Pacific, and a discussion of the genus Meliiderma
Two new species of Chondrocladia are described from the deep Pacific, off New Zealand and South Australia. These presumably carnivorous sponges are characterized by the presence of a sheath of special spicules along the stalk, for which the new term ‘trochirhabd’ is coined. Similar spicules were known from fossil strata of the Early Jurassic, suggesting that Cladorhizidae were already present i...
متن کاملA new species of Lissodendoryx (Anomodoryx) Burton, 1934 (Porifera: Demospongiae: Poecilosclerida) from deeper waters off the Atlantic coast of Brazil.
The members of Lissodendoryx Topsent, 1892a are recognized by a spicule combination of ectosomal tylotes or strongyles, isodictyal reticulate architecture, arcuate isochelae and sigmas (Hofman & Van Soest 1995; Van Soest 2002). Five subgenera of Lissodendoryx, are recognized (Van Soest 2002): Lissodendoryx (Acanthodoryx) Lévi, 1961, L. (Anomodoryx) Burton, 1934, L. (Ectyodoryx) Lundbeck, 1909, ...
