This study investigates the impact of plastic pollution on marine biodiversity in Italy, using digital media platforms like Google, Facebook, and Instagram to gather data. The research reveals that marine plastic litter has adverse effects on various marine species, including reptiles, mammals, sea birds, fish, crustaceans, and mollusks, with endangered and vulnerable species being particularly affected. The loggerhead sea turtle (*Caretta caretta*) is the most frequently recorded species entangled in plastic litter. Abandoned, lost, or discarded fishing gear (ALDFG) is identified as the primary contributor to entanglement. The study highlights the need for collaborative efforts among stakeholders and policymakers to effectively manage marine plastic litter. It also emphasizes the importance of citizen science and social media in documenting and addressing the issue of marine plastic pollution. The findings suggest that GSA 10 is the most severely affected area, and the study provides a preliminary database for documenting entanglement and ingestion cases, which can be useful for developing conservation measures in Mediterranean subareas.This study investigates the impact of plastic pollution on marine biodiversity in Italy, using digital media platforms like Google, Facebook, and Instagram to gather data.
