The VeriFish “Discover the Diversity of the Ocean” poster and puzzle are educational media products developed within the Horizon Europe VeriFish project to support seafood literacy, biodiversity awareness, and informed seafood consumption choices. The poster presents 136 seafood species assessed by the VeriFish project, combining detailed species illustrations with scientific and common names. It is designed as a visual learning resource for educators, children, consumers, consumer associations, and outreach organisations interested in exploring the diversity of fish and seafood species and the complexity of seafood sustainability. The resource is connected to the broader VeriFish Indicator Framework, which organises information across three complementary dimensions of seafood sustainability: environmental sustainability, socio-economic aspects, and nutritional value. By linking species identification with accessible visual communication, the poster helps users better recognise marine biodiversity and understand that responsible seafood consumption depends on more than a single indicator. The poster is also available in a puzzle format, offering a hands-on and interactive way to engage with the same content. This version is particularly suitable for classrooms, public engagement activities, workshops, awareness campaigns, and informal learning contexts. Both formats include QR codes linking users to the VeriFish web app and project website, where further information on species, sustainability indicators, factsheets, and related educational materials can be accessed. This media product contributes to the VeriFish objective of transforming complex seafood sustainability data into accessible, reusable and engaging communication tools for citizens, educators, and seafood value-chain stakeholders.
