On 16 June 2022, two specimens of Pomacanthus maculosus (Forsskål, 1775) were observed in the Syrian marine waters. One specimen was captured and classified, measured, preserved in formaldehyde and deposited at Tishreen University. It is a second substantiated record in the Levant Basin, and the first for the Syrian coast. The successful establishment of a viable population of P. maculosus in the Mediterranean Sea remains a suitable hypothesis which cannot be totally ruled out.

The eastern part of Bulgaria entirely borders the Black Sea, which defines it as a maritime country. The Bulgarian coast is an important fishing region for local people and has a high potential for interactions between fisheries and cetaceans. Depredation caused by cetaceans and damage to fishing gears can potentially lead to substantial economic loss for fishermen, while cetacean bycatch raises conservation concerns. Over the period 2016 - 2019, we conducted face-to-face interviews with fishermen in local fishing areas to better understand the fisheries – cetacean interactions in the Bulgarian part of the Black Sea. The research objectives were to identify the current fishermen’s attitudes toward cetaceans, understand the damage caused by local marine mammals to the different types of fishing gear, and gather fishermen’s proposals to resolve the problems. To record all of this, a specially designed structured survey was conducted. The results showed that fishermen’s attitude towards cetaceans was mostly positive and was not influenced by the type of fishing gear used. We found that fisheries - cetacean interactions are frequent, especially with dalyans gear and set gillnets. Cetacean bycatch mortality was reported to be highest for set gillnets, and the most vulnerable species was the Phocoena phocoena. Although interview data may be biased due to differences in perceptions and experience of the interviewees, and therefore should be interpreted with caution, this method allowed us to cover multiple types of interactions between cetaceans and Bulgarian fisheries.

This study reports the occurrence of the non-native red alga Caulacanthus okamurae, previously unknown on the Slovenian coast (Gulf of Trieste, northern Adriatic Sea). The distribution of the species, its abundance, morphological characteristics and reproductive phenology are described. The study is based on seasonal sampling conducted during one year, from winter to autumn 2021, on two different substrates (limestone and sandstone) of the midlittoral zone, and showed a moderate variation in the biomass of C. okamurae populations between the winter-spring and summer-autumn periods. The native algal assemblages of the two substrates impacted by C. okamurae were characterized by generally limited species diversity and consisted mainly of small-sized species with simple morphology. During the study, in addition to non-fertile thalli of C. okamurae, tetrasporophytic thalli with tetrasporocysts and female gametophytes with cystocarps were found.

This review first pays tribute to the famous Croatian oceanographer, Mira Zore-Armanda, and her seminal work on the Adriatic water masses in 1963, and emphasises the importance of the densest Mediterranean water mass: North Adriatic Dense Water (NAddW). This water mass is generated through substantial wintertime surface cooling and evaporation over the wide northern Adriatic and is known to (1) influence the Adriatic-Ionian thermohaline circulation, (2) bring oxygen and carbon to the deep Adriatic layers and, (3) more generally, have a substantial impact on the physics and biogeochemistry of the whole Adriatic. Second, the NAddW physics, from preconditioning, through generation and spreading, to accumulation in Adriatic depressions, is reviewed. Then, the temporal evolution of the NAddW properties influenced and connected to (1) basin-wide interannual and decadal variability and (2) trends towards warmer and saltier source characteristic due to ongoing climate change, is discussed. The importance of long-term observations and atmosphere-ocean modelling in event, decadal and climate studies is then presented. Finally, a review of the identified gaps and perspectives for future research is concluding this article.

This study presents the results of the examination of cephalopod remains extracted from the digestive tract of 40 loggerhead turtles, Caretta caretta, stranded along the Campanian coasts (Southern Italy, eastern Tyrrhenian Sea). We retrieved the remains of 23 cephalopods from 16 turtles (frequency of occurrence = 40%). They belonged to Sepia officinalis (19 specimens) and Octopus vulgaris (2 specimens), both of them benthic neritic species, and Histioteuthis reversa (2 specimens), an oceanic species. Accordingly, loggerheads appear to feed both on the bottom, seemingly in shallow waters, and in the open seawater column; both on muscular items (S. officinalis and O. vulgaris) and ammoniacal ones (H. reversa). This is the first record of H. reversa as a prey of the loggerhead turtle.

The results of a study on morphological features and reproductive phenology of the brown alga Cystoseira foeniculacea f. tenuiramosa (Ercegović) A. Gómez Garreta, M.C. Barceló, M.A. Ribera & J. Rull Lluch from the marine lagoon of Strunjan (Gulf of Trieste), are reported. Based on monthly samplings carried out during one year period, it was observed that this species shows considerable seasonal morphological variations. The Strunjan marine lagoon appears to be the only location of the Slovenian coast where population of this taxon occur. Based on the high associated biodiversity, we propose the inclusion of this population in the conservation management plans in the area.

Three species of Sphyrna (S. lewini, S. mokarran and S. zygaena) are known to inhabit the present-day Mediterranean Sea, whereas uncertainties exist about the presence of S. tudes in the same basin. Indeed, the presence of this typically westernAtlantic shark in the Mediterranean Sea is supported by as few as two historical specimens that were captured at Nice (southeastern France) and Leghorn (northern Tyrrhenian coast of central Italy). Here, we provide a redescription and an updated taxonomic identification of the Leghorn specimen of smalleye hammerhead, which is currently kept in the zoological collection of the Natural History Museum of the University of Pisa and is believed by some authors to represent a misidentified representative of S. lewini. Based on first-hand observations, we confirm the taxonomic identification of this specimen as belonging to S. tudes. Considering the ontogenetically young nature of both the Nice and the Leghorn specimens of S. tudes, parturition in the Mediterranean Sea is hypothesised, which in turn may evoke the occurrence of a population of smalleye hammerheads inhabiting this basin at least as recently as the early 19th century.
已知有三种Sphyrna (S. lewini, S. mokarran和S. zygaena)栖息在今天的地中海，而在同一盆地是否存在S. tudes则存在不确定性。事实上，这种典型的西大西洋鲨鱼在地中海的存在，得到了在尼斯(法国东南部)和里霍恩(意大利中部第勒尼安北部海岸)捕获的两个历史标本的支持。在此，我们对目前保存在比萨大学自然历史博物馆的Leghorn小双髻鲨标本进行了重新描述和更新的分类鉴定，该标本被一些作者认为是S. lewini的错误代表。根据第一手的观察，我们确认该标本的分类鉴定属于S. tudes。考虑到尼斯和莱格霍恩的S. tudes标本在个体发育上都很年轻，在地中海分娩是假设的，这反过来可能会引起至少在19世纪初居住在这个盆地的小双髻鲨种群的出现。

Many biological aspects of deep-water sharks are poorly known due to their rarity and difficulties in conducting detailed research on them. The angular roughshark (Oxynotus centrina) is a rare species, critically endangered in the Mediterranean Sea, of which records are scarce across this region. Here we present a record of a female neonate O. centrina from the south-eastern Adriatic Sea, caught by a Montenegrin commercial trawler. Scientific observers were present on-board and collected the specimen, which was subsequently analysed in the laboratory. The specimen was 225 mm long (TL), weighed 59.6 g and had an unhealed umbilical scar. To date, records of this species in the Adriatic Sea have comprised of both adult and older juvenile individuals, but no records of neonates were found in the published literature. In this work, the basic biological observations of the specimen are reported.
