Following the recent surge in purple jellyfish sightings, the growing presence of the silver-cheeked toadfish — known locally as lagocephalus — has added to the anxiety of sea-goers wary of marine life. Though first recorded in the southeastern Mediterranean, this toxic, invasive fish has gradually expanded its range across Greek waters, driven by climate change and shifting sea temperatures. In response, the Greek government has introduced a bounty of €5.30 per kilogram to encourage its removal.
Mapping the Spread
A digital map created using Google My Maps and maintained by ELNAIS — Greece’s Early Warning System for Alien Species — tracks confirmed sightings of Lagocephalus sceleratus across the country this year. The map shows concentrations around Crete, the Dodecanese, the Cyclades, and the Central and Northern Aegean Sea. Similar patterns have been reported along the coasts of Cyprus and Turkey.
How to Read the Map
Blue pins on the interactive map represent officially verified records of lagocephalus sightings. The map is publicly accessible and regularly updated as part of national efforts to monitor and manage invasive marine species.
