The Salento peninsula is a portion of the Italian mainland separating two distinct Mediterranean basins, the Ionian and the Adriatic seas. Several authors have studied the marine Heterobranchia (Mollusca, Gastropoda) fauna composition living in the Ionian Sea, but to date further knowledge regarding this interesting group of mollusks is still needed. Recent studies have corroborated the peculiarity of the Mediterranean Sea showing high levels of endemism and cryptic diversity. On the other hand, marine sea slugs have been revealed to be important indicators of the marine ecosystem’s health, due to their species-specific diet that consist of a vast variety of sessile and benthic invertebrates. A baseline study of the marine Heterobranchia diversity is therefore a necessary step to reveal the hidden diversity and to monitor the possible presence of alien species. The present study shows results from approximately 600 scientific dives carried out during a nine-year period in all of the main submarine habitats of the studied area, while accounting for the marine Heterobranchia from both the Ionian and Adriatic Seas. With this contribution, the list of marine Heterobranchia inhabiting the Salento Peninsula rises to 160. Furthermore, it also reports, for the first time, the presence of one alien species and three new records for Italian waters. Ecological notes and geographical distribution for each added species are provided together with animal iconography, consisting mainly of in situ photographs, for species identification.

Abstract The floristic investigation of the Ionian island of Kalamos resulted in the addition of 275 specific and infraspecific taxa, which are reported here, to a present total of 502 taxa. For each newly recorded taxon local distribution and habitat types are presented. Convolvulus pentapetaloides and Malcolmia graeca subsp. hydraea are reported for the first time from the Ionian islands. Some of the new records concern rare taxa in Greece or regional endemics, which are, therefore, chorologically significant, such as Alkanna corcyrensis, Stachys ionica, Heptaptera colladonioides. A brief description of some of the vegetation types of the island is given. The results of floristic analysis and phytogeographical aspects demonstrate the pronounced Mediterranean character of the island’s flora.

The Collective Article ‘New Mediterranean Biodiversity Records’ of the Mediterranean Marine Science journal offers the means to publish biodiversity records in the Mediterranean Sea. The current article is divided in two parts, for records of native and alien species respectively. The new records of native species include: the neon flying squid Ommastrephes bartramii in Capri Island, Thyrrenian Sea; the bigeye thresher shark Alopias superciliosus in the Adriatic Sea; a juvenile basking shark Cetorhinus maximus caught off Piran (northern Adriatic); the deep-sea Messina rockfish Scorpaenodes arenai in the National Marine Park of Zakynthos (East Ionian Sea, Greece); and the oceanic puffer Lagocephalus lagocephalus in the Adriatic Sea.The new records of alien species include: the red algae Antithamnionella elegans and Palisada maris-rubri, found for the first time in Israel and Greece respectively; the green alga Codium parvulum reported from Turkey (Aegean Sea); the first record of the alien sea urchin Diadema setosum in Greece; the nudibranch Goniobranchus annulatus reported from South-Eastern Aegean Sea (Greece); the opisthobranch Melibe viridis found in Lebanon; the new records of the blue spotted cornetfish Fistularia commersonii in the Alicante coast (Eastern Spain); the alien fish Siganus luridus and Siganus rivulatus in Lipsi Island, Dodecanese (Greece); the first record of Stephanolepis diaspros from the Egadi Islands Marine Protected Area (western Sicily); a northward expansion of the alien pufferfish Torquigener flavimaculosus along the southeastern Aegean coasts of Turkey; and data on the occurrence of the Lessepsian immigrants Alepes djedaba, Lagocephalus sceleratus and Fistularia commersonii in Zakynthos Island (SE Ionian Sea, Greece).

<p>New records of rare gastropod species are reported. A live specimen of <em>Erato voluta</em> (Gastropoda: Triviidae), a species considered to have a far more southern distribution, has been found from outside the Trondheimsfjord. The specimen was sampled from a gravel habitat with <em>Modiolus</em> shells at 49–94 m depth, and was found among compound ascidians, its typical food resource. Live specimens of <em>Simnia patula</em> (Caenogastropoda: Ovulidae) have during the later years repeatedly been observed on locations on the coast of central Norway, which is documented by in situ observations. In Egersund on the southwest coast of Norway a specimen of <em>Simnia hiscocki</em> was in March 2017 observed for the first time from Norwegian waters, a species earlier only found on the south-west coast of England. Also this was documented by pictures and in situ observations. The specimen of <em>Simnia hiscocki</em> was for the first time found on the octocoral <em>Swiftia pallida</em>.</p><p> </p>

Of Greece

An update of the inventory of alien marine species from the coastal and offshore waters of Greece is presented. Records were compiled based on the existing scientific and grey literature, including the HCMR database of Greek alien species (ELNAIS), technical reports, scientific congresses, academic dissertations, websites, and unpublished/personal observations. 47 species were added to the inventory, including 34 invertebrates, one vertebrate (fish), three plants, eight protozoa, and one cyanobacterium. With the new records, the inventory of alien marine species of Greece now includes a total of 237 species (33 macrophytes, 131 invertebrates, 42 vertebrates, two bacteria and 29 protozoans). Among these, the presence of the gastropodHypselodoris infucata, the bivalvesDendrostrea frons and Septifer forskaliand the chondrichthyan Rhizoprionodon acutus is reported here for the first time. Based on molecular analysis, the occurrence of Bulla arabica in Greek waters is confirmed, and the suggestion that previous records of Bulla ampulla in the Mediterranean should be considered as misidentification of B. arabica is further supported. The acclimitization status of earlier records was revised in the light of new data, and thus the fishEnchelycore anatina, Seriola fasciata andTylerius spinosissimus, the red algaeHypnea cornuta and Sarconema scinaioides, the scyphomedusaCassiopea andromeda, the cephalopodSepioteuthis lessoniana, the nudibranchChromodoris annulata and the bivalvesGastrochaena cymbium andPseudochama corbieri were upgraded from casual records to established populations. The increased rate of introductions of warm water species confirms previous findings, which link the rate of introduction in the eastern Mediterranean to climate change.

<p>The molluscan fauna of Isla del Coco has recently been well documented, but the heterobranch sea slugs, traditionally called “opisthobranchs”, remain poorly known. We report 13 new records, increasing the total to 40 species. Of the 13 newly discovered species, the following species had not been previously recorded along the Pacific Costa Rican mainland: <em>Berthella californica </em>(Dall, 1900), <em>Peltodoris rubra</em> (Bergh, 1905), <em>Dendrodoris albobrunnea </em>Allan, 1933, <em>Doriopsilla</em> cf. <em>spaldingi </em>Valdés &amp; Behrens, 1998, <em>Glaucus</em> cf. <em>marginatus</em> (Reinhardt &amp; Bergh, 1864), and <em>Flabellina</em> sp. Additionally, we report <em>Peltodoris rubra</em>, previously known from the Indo-Pacific, for the first time in the Eastern Tropical Pacific.</p><div> </div>

The black coral fauna of Bermudan waters is poorly known, in large part due to the logistical challenges of surveying deep-water (>50 m) environments where most species occur. In 2016, the Nekton Expedition sought to survey the deep-water biodiversity around Bermuda using manned submersibles and mixed-gas technical SCUBA. A total of 28 black coral specimens were collected, and these were examined based on skeletal spine morphology, polyp morphology, colony branching pattern and in situ photographs. The specimens were assigned to seven species in three families and four genera, including (1) Antipathes atlantica Gray, 1857, (2) Antipathes furcata Gray, 1857, (3) Stichopathes pourtalesi Brook, 1889, (4) Stichopathes sp., (5) Distichopathes filix (Pourtales, 1867), (6) Tanacetipathes hirta (Gray, 1857), and (7) Tanacetipathes tanacetum (Pourtales, 1867). Of these, three species (Stichopathes sp., S. pourtalesi, and D. filix), one genus (Distichopathes) and one family (Aphanipathidae) are reported from Bermudan waters for the first time, thereby increasing the known black coral diversity of Bermuda to twelve species, five genera and four families. The diagnostic characters of the taxa identified as part of this study are illustrated and described.

Behavioural Adaptations

Predator dietary studies often assume that diet is reflective of the diversity and relative abundance of their prey. This interpretation ignores species-specific behavioural adaptations in prey that could influence prey capture. Here, we develop and describe a scalable biologging protocol, using animal-borne camera loggers, to elucidate the factors influencing prey capture by a seabird, the gentoo penguin ( Pygoscelis papua ). From the video evidence, we show, to our knowledge for the first time, that aggressive behavioural defence mechanisms by prey can deter prey capture by a seabird. Furthermore, we provide evidence demonstrating that these birds, which were observed hunting solitarily, target prey when they are most discernible. Specifically, birds targeted prey primarily while ascending and when prey were not tightly clustered. In conclusion, we show that prey behaviour can significantly influence trophic coupling in marine systems because despite prey being present, it is not always targeted. Thus, these predator–prey relationships should be accounted for in studies using marine top predators as samplers of mid- to lower trophic-level species.

This is the fifth publication describing species of sea slug heterobranchs, originally based on collections from the Red Sea by the author on four expeditions carried out in 1983 and 1990, with the addition of specimens subsequently collected by underwater photographers who were stimulated by the book "Sea Slugs of the Red Sea". So much material has been amassed that only the new species and new Red Sea records of chromodorids are described in this paper, with an appendix listing specimens of previously recorded species. Three new species are described in detail and illustrated, belonging to three different genera: Doriprismaticakyanomarginata sp. n., Glossodoriskahlbrocki sp. n., and Goniobranchuspseudodecorus sp. n. One western Pacific species is recorded for the first time in the Red Sea, Goniobranchuscollingwoodi (Rudman, 1987). The nomenclature of Verconiasudanica is discussed and stabilised.
