“…The blue swimming crab Portunus segnis (Forsskål in Niebuhr, 1775) (Malacostraca: Decapoda: Portunidae), is one of the earliest Lessepsian invaders of the Mediterranean Sea, recorded since decades in various areas of the Mediterranean (Galil, 2011). Its presence in the Gulf of Gabes (south-eastern Tunisian coasts), however, is very recent, and after its first record in October 2014, it only occurred in the area accidentally and with very low abundances (Rabaoui et al, 2015).…”

“…Arthropods epitomize this on-going invasion process: in 2008, the CIESM Atlas of Exotic Species listed 70 alien species; three years later, Galil (2011) listed 106 species, while Nunes et al (2014) counted 242 species. According to this recent study, lessepsian migrants from the Red Sea through the Suez Canal provide a considerable contribution (90 species), whose importance is expected to increase due to climate warming (Raitsos et al, 2010;Galil & Goren, 2014).…”

“…Among other non-indigenous arthropods, the blue crab Callinectes sapidus Rathbun, 1896 (Decapoda, Brachyura, Portunidae) is characterized by an almost ubiquitous distribution in Mediterranean waters (Galil, 2011). The species, native of western Atlantic coastal habitats, was introduced in Europe presumably by ballast waters and was recorded for the first time on the Atlantic coasts of France in 1900 (Bouvier, 1901).…”

The Atlantic blue crab Callinectes sapidus is to date widely distributed in the Mediterranean Sea, where is recognized as an Invasive Alien Species. Noticeably, while records of its occurrence are increasing, quantitative information on its functional role in the benthic food webs of invaded coastal habitats are scarce.Here, carbon and nitrogen isotopic signatures were measured in C. sapidus and other representative taxa of the benthic flora and fauna sampled in summer in the Parila Lagoon, a coastal basin located in the Neretva River estuary area (Croatia). d15N values of individual blue crab specimens were used to calculate their trophic position (TP) , using the filter feeder mussel Mytilus galloprovincialis as the isotopic baseline. In general, the isotopic signature of C. sapidus was comparable with those characterizing invertebrate and fish predators (e.g., Hexaplex trunculus, Gobius niger). An average trophic position of 3.73 was estimated for the blue crab population. However, a considerable inter-individual variation was observed in TP values, significantly related with the size of the specimens. Interestingly, a hump-shaped quadratic polynomial resulted the best fitting model for the data, characterized for small-size individuals by a positive body size-TP relationship, leveling or even turning negative for larger adult crabs. The interplay between environmental factors and ontogenetic diet shifts in determining the trophic position of the blue crab and, ultimately, its ecological impact on the benthic community of the Parila Lagoon is discussed.

“…Therefore, it seems unlikely that Paranebalia might have previously been mistaken in the Mediterranean for any other leptostracan. It may represent a new species (see below) or possibly a new record of a known taxon; if the latter, it might be a recently introduced species which would explain the lack of previous findings as many small exotic crustaceans have been found in the Mediterranean recently (Galil, 2011;Ros et al, 2014). Further sampling will be necessary to allow for a complete taxonomic description, and to assess its ecology and actual distribution.…”

Benthic monitoring of the marine shallow bottoms off Menorca (Balearic Islands, western Mediterranean) has yielded several specimens of the leptostracan genus Paranebalia Claus, 1880. This finding constitutes the first report of the genus from European latitudes and the Mediterranean Sea and therefore the third leptostracan genus known from the Mediterranean. Specimens are described, illustrated and compared to other known species; they might represent a new species but their state of maturity and the lack of an appropriate diagnosis for the type species of the genus, Paranebalia longipes (Willemöes-Suhm, 1875), did not allow to confirm its taxonomic status.
