Deadly invasive toadfish from Red Sea threatens Greece

Thursday, 9 July 2026/Source: CretaOne/1 min read

The silver-cheeked toadfish (lagocephalus), a highly toxic invasive species, has become a growing threat in Cretan and broader Greek waters. Originally from the Red Sea, it has spread rapidly across the Mediterranean and is now frequently caught by local fishermen, raising serious safety concerns. The fish contains tetrodotoxin, a potent poison with no known antidote, and must never be eaten. Researchers are now investigating whether loggerhead sea turtles (caretta caretta), natural predators of the species, could help control its population. For visitors, the key precaution is simple: do not purchase or consume any fish labeled or resembling pufferfish. When buying seafood at local markets or tavernas, stick to well-known species and ask fishermen directly about the catch. Authorities continue to monitor the situation across Cretan coastal areas.
