An invasive and highly toxic fish species, Lagocephalus sceleratus, has recently been spotted in the Mediterranean Sea by Croatian researchers — raising serious concerns for human safety, marine biodiversity, and ecosystem balance.
A New Threat in Mediterranean Waters
When thinking of dangerous animals, one might picture lions, crocodiles, or even mosquitoes. However, the oceans harbor their own deadly creatures — such as the Lagocephalus sceleratus, commonly known as the silver-cheeked toadfish or balloonfish.
Originally found in the tropical and equatorial zones of the Indian and Pacific Oceans, this toxic fish has now made its way into the Mediterranean. Researchers from the Juraj Dobrila University of Pula and the Institute of Oceanography and Fisheries in Split confirmed its presence along the Croatian coast.
Toxic and Harmful to Humans
As detailed in a study published on March 20 in Acta Ichthyologica Et Piscatoria, this species is not only disruptive to local marine ecosystems, but also poses a severe risk to humans if consumed.
The fish’s organs and flesh contain tetrodotoxin, a potent neurotoxin that can block nerve signals within minutes. Effects include muscle paralysis, vision problems, and in severe cases, death.
Moreover, its powerful beak-like jaws can cause serious injury — even partial finger amputation — as reported by SciTechDaily.
An Ecological Threat
Beyond its toxicity, Lagocephalus sceleratus threatens native marine life by competing for food and altering ecological balances. Its rapid spread across the Mediterranean underscores the urgent need for monitoring and coordinated action among coastal nations.
