The submarine areas associated to the Jaizkibel mountain show a high diversity of habitats and species. With the aim of contributing to this knowledge, the OCEANA association carried out several immersions from 2008 to 2010. In this work we detail the results of such immersions. Overall, we identified more than 300 species (all of which … Read more
Marine litter has become a worldwide environmental problem, tainting all ocean habitats. The abundance, distribution and composition of litter and its interactions with fauna were evaluated in the upper S. Vicente canyon using video images from 3 remote operated vehicle exploratory dives. Litter was present in all dives and the abundance was as high as … Read more
The present note reports a new record of Rosalinda incrustans (Cnidaria: Hydrozoa) since its last reliable record in the Mediterranean Sea in 1958. Several colonies were recorded on the spider crab Anamathia rissoana off the Balearic Islands. The taxonomic history of R. incrustans, considered a putatively extinct species in a recent paper, is reviewed. … Read more
The sea star Coronaster briareus (Verrill Am J Sci (Ser III), 1882) is reported for the first time from the Mediterranean Sea. A total of 26 individuals were sighted in Maltese waters during ROV surveys made in July 2015 and June–July 2016. The identity of the species was confirmed through morphological examination of a specimen … Read more
Sharing experiences and results among scientists and managers working on seagrass restoration was the main objective of the first European Seagrass Restoration Workshop that gathered researchers from around Europe. The meeting was the first forum in Europe that allowed for scientists, NGOs, and managers to interact and share their experiences relating to seagrass restoration and … Read more
The underestimation of fisheries removals is a global issue that spans countries from different continents and different socio-economic situations. Underestimation of catches is especially important in countries where fishing fleets are highly diversified, the enforcement of fishing management is low, data availability is poor, and there is high demand for fish products in local markets. … Read more
Live colonies of the precious red coral Corallium rubrum have previously been recorded at depths of 600-800 m in the Sicily Channel, but deep-water populations of this species remain poorly known. During a recent research expedition within the 25 nautical mile Fisheries Management Zone around the Maltese Islands, numerous colonies growing deeper than 800 m, … Read more
Coralligenous and rhodoliths beds are two types of biogenic habitats, structured by calcareous red algae. Widely distributed along the Mediterranean Sea, these formations create complex three-dimensional structures, where countless marine species –including those of high commercial value and endangered ones– feed, rest and nest. These characteristics confer the two habitats a great ecological and economic … Read more
Oceana’s exploratory ROV’s dives in Western Mediterranean seamounts have collected more than 300 hours of video from deepsea ecosystem. Findings of threatened species and habitats, like carnivorous sponges, elasmobranches, coral gardens, sponge aggregations, coralligenous beds, etc. or even new species for science like giant foraminifera (Astrorhizidae), or new species for the Mediterranean (i.e. Anomocora fecunda), … Read more
New records of the Dendrophylliidae species Dendrophyllia laboreli in the Mediterranean Sea (Alboran basin), South Portugal and also in the Canaries are biogeographically relevant. The presence in the Mediterranean Sea and the recent wide distribution towards new locations in Canary Islands of such species is discussed in relation to the climatic fluctuations. In the Canaries … Read more
