Toxic, bone-crushing fish from Hell terrorizes vacation waters

Key Points:

• The invasive silver-cheeked toadfish, a toxic pufferfish species with powerful jaws, is spreading throughout the Mediterranean, prompting local authorities to warn tourists about bite risks and take protective measures for swimmers.
• Originating from the Red Sea via the Suez Canal, the fish carries tetrodotoxin, a deadly neurotoxin found in its flesh and organs, and can cause serious injuries with its bone-crushing bite, although attacks on humans are rare and usually occur when the fish is handled.
• A 2024 study recorded 198 human incidents related to the fish in the eastern Mediterranean from 2004 to 2023, including 28 attacks, 144 non-lethal poisonings, and 27 fatalities from consumption, with incidents increasing notably after 2019.
• Greek authorities have installed floating barriers in the Gulf of Euboea to protect swimmers, and the government is incentivizing fishermen with payments to catch the invasive species, which has few natural predators and damages fishing gear.
• The Hellenic Red Cross and other experts emphasize that no part of the fish is safe to eat due to toxin distribution, and consumption can lead to paralysis, respiratory failure, and heart failure, while toxicity varies among pufferfish species.
