Update of the Leatherback sea turtle Dermochelys coriacea (Vandelli, 1761) and Green turtle Chelonia mydas (Linnaeus, 1758) observations in Italy (Reptilia Testudines)

In this work, we collected records since 2002 of Leatherback sea turtle Dermochelys cori-acea (Vandelli, 1761) and since 2009 of Green turtle Chelonia mydas (Linnaeus, 1758). These observations have been made using scientific literature, citizen science programs, and social networks as data sources (Reptilia Testudines: Dermochelyidae and Cheloniidae). The aim of this work is to create a complete and up-to-date dataset. About one fifth of these new records comes from Facebook groups dedicated to biodiversity, thus underlining the usefulness of unconventional sources to gather data on species with poorly known distributions.
