Greek authorities issue warnings as the invasive silver-cheeked toadfish spreads across the Mediterranean and Black Seas
Greek authorities are issuing public advisories to warn swimmers and tourists about the silver-cheeked toadfish, an invasive puffer fish species expanding rapidly across the Mediterranean and Black Seas. The fish, also known as the harefish or lagokefalos, entered the region via the Suez Canal and is characterized by its powerful, beak-like jaws and a potent neurotoxin called tetrodotoxin. While the fish does not routinely attack humans, its strong jaws can cause severe lacerations and heavy bleeding if it interacts with swimmers or fishermen. Furthermore, the fish's flesh and internal organs contain a deadly toxin that can cause heart failure and paralysis if consumed, leading to the European Union to prohibit its sale and consumption in Greece. To manage the population, the Greek government has introduced cash rewards for fishermen to catch the nuisance fish, while municipalities have installed floating barriers and protective nets to safeguard citizens. Experts note that rising sea temperatures are creating favorable conditions for this tropical species to make a long-term presence in European waters.
