“…In the light of the data deficiency for rare and elusive species, several authors have proposed the use of alternative sources of information, such as local ecological knowledge (Stephenson et al, 2016) or citizen science (Giovos et al, 2019a). Citizen science -an approach where the general public participates in scientific data collection-has been proven to be a valuable tool for gathering information about rare and endangered species, e.g., abundance (Becerril-García et al, 2020), distribution (Araujo et al, 2020;McDavitt & Kyne, 2020), migration routes (Armstrong et al, 2019;, behavioural patterns (Chin, 2014;Jambura et al, 2020), and critical habitats (Norton et al, 2012;Jiménez-Alvarado et al, 2020).…”

The Mediterranean Sea is an extinction hotspot for sharks, skates, and rays, with at least half of all species being threatened. The sandbar shark Carcharhinus plumbeus is among the most threatened species and is declared endangered (EN) in the Mediterranean according to the IUCN Red List of Threatened Species. The Adriatic Sea was previously proposed to be an important nursery area for this species based on sporadic sightings of neonates and juveniles. However, this species is generally considered to be rare in this region, and reports of its presence are scarce. Here, we present new records for the sandbar shark in the Adriatic Sea and review spatial and temporal data accumulated from literature, museum specimens, and citizen science initiatives in an attempt to assess the distribution and seasonality of this species. The majority of the records were from neonate and juvenile sandbar sharks, and three hotspots for their occurrence could be identified: (1) the Emilia-Romagna region, (2) the Veneto region, and (3) the Gulf of Trieste. Our data indicate a high concentration of sandbar sharks around the delta of the Po river, emphasising the need for scientific surveys in this confined area in order to confirm a possible nursery ground. Data collected by citizen science initiatives reveal that this species is still present in the Adriatic Sea and might be more abundant than previously thought, underlining the potential of citizen science as a valuable tool to monitor the distribution of rare and endangered species.

In November 2021, a female bigeye thresher shark was incidentally caught by a pelagic drifting longline off southern Cyprus, corresponding to the second documented species record at country level. Main biological features and an extended list of morphometric measurements are presented in comparison with the previous species records in the Mediterranean. The diet analysis highlighted the impact of marine species invasion in the Mediterranean food webs and documented the presence of the angel squid in Cypriot waters for the first time. The species presence in the basin is revised and discussed.
