Galeus melastomus is the most common Pentanchidae in the Mediterranean Sea. A scavenger and opportunistic feeder, and despite the wide distribution, little is known about its feeding habits in Italian waters. The main purpose of this study was to investigate the diet of the blackmouth catshark by analysing the stomach contents. The specimens analys...

Elasmobranchs are highly threatened globally; 25% of species are estimated to be endangered by the IUCN. This disturbing trend is more significant in the Mediterranean, where over half of the species represented in the basin are at risk. Yet, there is still a considerable knowledge gap about distribution, abundance, and critical habitats of Elasmob...

In Gansbaai (South Africa), at Dyer Island Nature Reserve, a large White shark population is present and can be observed due to the support of local ecotourism operators authorised to reach the field observation sites. Between 2009 and 2019, it was possible to create a database including information about each individual observed. In total, 423 whi...

In this contribution the checklist of chondrichthyans of Calabria (Central Mediterranean, southern Italy) is reported. Data presented is derived from twenty years of opportunistic and active surveys from 2000 to 2020. A total of 55 species of chondrich-thyans is present in Calabrian seas: 33 sharks, 20 rays, and 2 chimaeras. These species represent...

In the years 2017, 2018 and 2019 the feeding behavior of the whale shark has been studied off Nosy Be Island (Madagascar). In particular, the investigations involved the description of the behavioral modules of the whale shark and their relationship with the phytoplankton communities. In total, 65 phytoplankton samples were collected in the followi...

I NDIVIDUAL IDENTIFICATION OF SHARKS THROUGH DORSAL FIN: A NEW APPROACH THANKS TO ADVANCES IN COMPUTER SCI ENCE

Individual surface behaviour of white sharks in the presence of bait has been studied from 2005 to 2017 at Dyer Island Natural Reserve (Sotuh-Africa). Observations were made from a commercial cage-diving boat. We observed 220 white sharks that exhibited 9 different types of of individual behaviour: parading, bait following, visual inspection, breac...

Studying the behaviour of the White Shark is a recent and big challenge. Optimising the photoidentification of White Shark dorsal fins is a basic goal, in order to compare behavioural information in both immature and mature specimens and between females and males. During a 6 years research, from 2009 to 2014, in South Africa, we observed 296 sharks...

The presence of the genus Nanna in Gabon is treated. Four species are recorded, two of which are new to science (N. molouba sp. nov. and N. semigrisea sp. nov.), and the hitherto unknown female of Nanna ceratopygia is described. A checklist and a key to the species of the genus Nanna are provided.
