The predatory activity of the asteroid Peltaster placenta (Müller and Troschel, 1842) on the black coral Parantipathes larix (Esper, 1790) is here described for the first time based on video footage obtained during a Remotely Operated Underwater Vehicle (ROV) survey conducted in the Pontine Archipelago (Southern Tyrrhenian Sea, Mediterranean...

This study provides taxonomic and distributional data of bryozoan species from the Ross Sea area, mainly around Terra Nova Bay, based on specimens curated at the Italian National Antarctic Museum (MNA, Section of Genoa). Bryozoan specimens were collected at 75 different sampling stations in the Ross Sea and in the Magellan Strait, in a...

Marine biogenic skeletal production is the prevalent source of Ca-carbonate in today's Antarctic seas. Most information, however, derives from the post-mortem legacy of calcifying or-ganisms. Prior imagery and evaluation of Antarctic habitats hosting calcifying benthic organisms are poorly present in the literature, therefore, a Remotely...

In the Antarctic seas, where hard substrates are scarce, the presence of secondary bio-substrates formed by calcareous organisms is an essential condition to increase the epibiosis and therefore the diversity of sessile benthic fauna. The aggregations of stylasterid hydrozoa, with their branched carbonate structures, are an example of a...

The sea star Hymenodiscus coronata is the only Mediterranean representative of the deepsea order Brisingida. In the North-eastern Atlantic Ocean, this species is known to create dense aggregations, while, in the Mediterranean basin, it is generally reported as scattered individuals. Through the analysis of the video footage obtained from an...
