Back to newsThe silver-cheeked toadfish (Lagocephalus sceleratus), an invasive species originally from the Indo-Pacific, has spread aggressively across the Aegean Sea and Cretan coastal waters over the past two decades. First recorded in Greek waters in the early 2000s, the species has now established a strong presence around Crete's coastline. The fish is highly toxic: its skin, organs, and flesh contain tetrodotoxin, a potent poison with no antidote. Swimmers and snorkelers should avoid touching any pufferfish spotted in the water. Fishermen are advised not to handle or consume any caught specimens. Local authorities and the Hellenic Ministry of Rural Development track sightings through an interactive mapping system. If you see one while swimming or diving, keep your distance and report it to local port authorities or your accommodation.
