In 2021, the Museum of Zoology "P. Doderlein" of the University of Palermo acquired a new specimen, the complete skeleton of Stenella coeruleoalba, a striped dolphin stranded in 2018 in Marinella di Selinunte, Castelvetrano (Sicily, Southern Italy). The project herein described is the result of a collaboration among the Bio-Reconstruction Laboratory of the IAS-CNR of Capo Granitola, the IZS of Palermo, the company Naturaliter and the Museum of Zoology "P. Doderlein". In Natural History Museums, cetaceans are an excellent tool to facilitate scientific dissemination aimed at the conservation of marine biodiversity. The work herein described is presented as an example of good practices in recovering a cetacean carcass that can otherwise be an expensive waste to manage.

The study examined the extent of the cetacean strandings in Italy, with a particular focus on Sicily Island. The paper aimed to contribute to the description of a pattern that contemplates the “regular and rare” cetacean species passage along the Sicilian coast. The estimate of marine cetacean strandings was extrapolated from the National Strandings Data Bank (BDS—Banca Dati Spiaggiamenti) and evaluated according to a subdivision in three coastal subregions: the Tyrrhenian sub-basin (northern Sicilian coast), the Ionian sub-basin (eastern Sicilian coast), and the Channel of Sicily (southern Sicilian coast). Along the Italian coast, more than 4880 stranding events have been counted in the period 1990–2019. Most of these were recorded in five Italian regions: Apulia, Sicily, Sardinia, Tuscany, and Calabria. Approximately 15% of the recorded strandings in Italy occurred on the Sicilian coast. In Sicily Island, 725 stranded cetaceans were recorded in 709 stranding events, resulting in approximately 20 carcasses every year; the total number of specimens identified to species level was 539. The distribution along the Sicilian coast was the following: 312 recorded in the Tyrrhenian sub-basin, 193 in the Ionian sub-basin, and 220 in the Channel of Sicily. Stenella coeruleoalba was the species that can be considered as the stable record along the time-lapse investigated, and some rare species have been recorded as well. The role of Sicily Island as a sentinel territory of the cetacean distribution for the central Mediterranean Sea and as a region receiving a marine resource suitable for the scientific research and cetological museum collections is discussed herein.

The Museum of Zoology "P. Doderlein" took part in the event " Esperienza inSegna 2020" where a scientific dissemination activity was planned and named "Ecological footprint: the game". The Museum has built an informal learning environment. The students of the University of Palermo carried out the project of scientific dissemination addressed to an audience mainly represented by younger students. It was an example of scientific communication from youngs to youngs. The student association Vivere Scienze MM.FF.NN. was a partner of the project as used in the past editions. The project outcome is here presented, and its strengths and weaknesses analyzed.
