“…Dead Dendrophyllia cornigera frames have been rarely ascertained on coral rubble ( Figure 5F). Surprisingly, no living colonies of this noticeable scleractinian (Castellan et al, 2019) have yet been detected in this area. A specimen of an undetermined nudibranch was observed grazing on living M. oculata ( Figure 6C).…”

Over 25 mounds have been identified in the Corsica Channel (Mediterranean Sea) through multibeam bathymetric mapping at depth of 400-430 m, with dimensions ranging from 70 to 330 m, achieving maximum heights of 25 m. Two mounds have been explored in detail using a remotely operated vehicle, revealing thick coral growth with a predominance of the branching scleractinian Madrepora oculata as main frame builder and subordinate Desmophyllum pertusum. The solitary scleractinians Desmophyllum dianthus and Javania cailleti add to the biodiversity here, which accounts for at least 50 macro-and megabenthic species. In consideration of the remarkable surface (ca. 5.3 km 2) covered by living corals, their density and healthy appearance, and discontinuity with other major cold-water coral (CWC) occurrences in the Mediterranean Sea, we propose that this area represents a distinct CWC province in a sector already known for the presence of pre-modern CWC mounds. Noticeably, well-developed contourite drift systems occur in the Corsica Channel, lending support to their strict spatial link with coral establishment at depth. The ecosystemic value of the new CWC province calls for proper conservation measures to ensure their present Good Environmental Status.

“…The BC seascapes and surrounding slope, between 200 and 1000 m, are characterized by several habitats, which include CWC ecosystems and sponge grounds [32][33][34][35][36][37][38][55][56][57]61,[73][74][75][76][77]. ROVs surveyed the BC and the surrounding areas (i.e., flanks, rims) 12 times (see Table 1).…”

There is growing awareness of the impact of fishery activities on fragile and vulnerable deep-sea ecosystems, stimulating actions devoted to their protection and best management by national and international organizations. The Bari Canyon in the Adriatic Sea represents a good case study of this, since it hosts vulnerable ecosystems, threatened species, as well as valuable commercial species, but virtually lacks substantial management plans for the sustainable use of resources. This study documents the high level of biodiversity of the Bari Canyon and the impact of human activities by analyzing remotely operated vehicle surveys and benthic lander deployments. An integrated socio-economic study provides information on fishing pressure in the Bari Canyon and in the surrounding areas. Finally, measures of conservation, protection, and management are discussed and suggested for this remarkable site in the context of the deep Mediterranean Sea.

“…Dendrophyllia develop complex bioconstructions in the Atlantic Ocean known as orange coral banks (D. ramea) and yellow coral banks (D. cornigera) (Arístegui et al 1987;Brito and Ocaña 2004;Ocaña et al 2009;Castellan et al 2019). In the Mediterranean, although present as isolated colonies or forming small patches, both Dendrophyllia species are found as associated fauna in large build-ups formed by the white corals M. oculata and Lophelia pertusa (Freiwald et al 2009).…”

Azooxanthellate corals are the most abundant macrofossils in the lower Pliocene deposits of the Manilva Basin (S Spain). In this paper, the cnidarian fossil assemblages have been studied in order to reconstruct the original communities and to depict the seascapes. Benthic foraminiferal assemblages associated with the corals have also been analysed to infer the palaeoenvironmental conditions in which they developed. Two sections have been studied. In the Canuto section, Coenosmilia fecunda dominates the cnidarian assemblage, followed by Asterosmilia cf. prolifera and Asterosmilia sp., which are all preserved as moulds and casts. Benthic foraminiferal assemblages indicate oligotrophic conditions and deposition from the middle platform to the upper slope. The Á lamos section is characterized by Madrepora oculata, Dendrophyllia ramea, Asterosmilia cf. prolifera, Asterosmilia sp., Coenosmilia fecunda, and gorgonians of the Isididae family (most likely Keratoisis melitensis and/or Lepidisis longiflora), as well as a basal holdfast attributed to a member of either Primnoidae or the Chrysogorgiidae family. Here, corals preserve their original skeletons. Benthic foraminifers suggest deposition in oligotrophic conditions in mid-outer platform settings. Corals in the Canuto section formed autochthonous fossil assemblages, while in the Á lamos section they were slightly displaced from their original growth positions to form parautochthonous fossil concentrations. The cnidarian community in the Canuto section was characterized by low-tier organisms either attached to hard substrates provided by skeletal remains (Coenosmilia fecunda) or inhabiting fine-grained bottoms (Asterosmilia spp.). In the Á lamos section, Coenosmilia fecunda and Asterosmilia spp. occupied the lowest tier levels. The gorgonians, isidids and members of the Primnoidae or Chrysogorgiidae families, colonized both soft and hard substrates, dominating the next tier level. Finally, Madrepora oculata and Dendrophyllia ramea settled on submarine cliffs or on large blocks derived from substrate, inhabiting the highest position in the community. Large specimens of gorgonians could have also occupied this position.
