With avvistAPP users can report the presence of sea walnuts, jellyfish, dolphins and turtles by taking a photo of the animal and sending it to researchers via the app. avvistAPP was developed in 2019 by OGS and Divulgando Srl thanks to the support of the Autonomous Region of Friuli Venezia Giulia, with the collaboration of APS Delta "Dolphins and turtles in the Gulf of Trieste".
