Pufferfish are increasingly being observed in Greek seas, prompting concern and expert guidance. These fish contain potent toxins, and while not typically aggressive, pose a risk if consumed. Experts emphasize that even small amounts of pufferfish toxins can be fatal. The recent appearance is likely linked to warming sea temperatures and changing marine ecosystems. Authorities are advising the public not to handle or consume any pufferfish found in Greek waters. Information campaigns are underway to educate fishermen and beachgoers about the dangers and proper procedures if encountering these fish. Further research is needed to understand the long-term impact of their presence on the local marine environment.
