Back to newsInvasive pufferfish known as silver-cheeked toadfish (Lagocephalus sceleratus) have been spotted in increasing numbers around Greek islands, including Crete, as the summer tourist season gets underway. These fish are recognizable by their unusually human-like teeth and inflated, round bodies. Their flesh contains a powerful neurotoxin called tetrodotoxin, which has no antidote and can be fatal if consumed. Fishermen across the region are raising concerns as the species disrupts local catches and poses a risk to those unfamiliar with it.
For visitors, the key precaution is straightforward: do not touch or handle any unfamiliar fish encountered while swimming or snorkeling, and never purchase or eat fish from unverified sources. The species is not aggressive and poses no direct threat in the water. If spotted, keep your distance and report sightings to local authorities.
