Deadly Invasive Pufferfish Now Spreads Throughout Crete's Waters

Saturday, 20 June 2026/Source: Google News/1 min read

The lagocephalus, a highly toxic invasive fish originally from the Indian and Pacific Oceans, has now spread throughout the waters surrounding Crete and the wider Aegean Sea. Maps tracking its presence show the species has established itself along virtually all of Crete's coastline. The fish contains tetrodotoxin, a poison with no known antidote that can be lethal even in small amounts. Tourists swimming and snorkeling in Cretan waters should be aware of its presence. The lagocephalus resembles a common pufferfish and should never be touched or consumed. Local fishermen are advised to discard it carefully if caught, without touching the skin or organs. Visitors who spot one on a beach or in the water should alert local authorities and keep a safe distance. Eating any fish purchased from unverified sources is discouraged.
