Back to newsThe silver-cheeked toadfish (lagokephalos), a toxic invasive species originally from the Indo-Pacific, has become a permanent presence in Cretan waters. The fish contains tetrodotoxin, a potent poison found in its skin, liver, and reproductive organs, with no known antidote. Greek authorities have banned its sale and consumption entirely. For tourists, the key risks are twofold: encountering one while swimming or snorkeling, and accidentally consuming it if mislabeled at a restaurant. The fish resembles edible species and can appear in coastal areas and harbors. Visitors are advised not to touch any unfamiliar fish in the water and to order seafood only from reputable establishments. If you suspect you have eaten lagokephalos and experience numbness, tingling, or difficulty breathing, seek emergency medical attention immediately.
