An unwelcome newcomer in the Med.
As the Mediterranean sea gets warmer and more saline, a species of puffer fish is growing bigger and expanding further, bringing danger to fishing industries and beach swimmers alike.
With its toxic flesh and bone-crushing jaws, the invasive species is expanding its range throughout the Mediterranean.
In some places, it’s causing local authorities to issue warnings to tourists about the risk of dangerous bites.
Fox News reported:
“Some places are even taking precautions to protect swimmers and bathers from the invasive silver-cheeked toadfish, also called harefish.
The fish reportedly entered the Mediterranean through the Suez Canal and has spread as sea temperatures have warmed. It carries tetrodotoxin, a deadly neurotoxin found primarily in its flesh and internal organs, and its powerful beak-like jaws can shred fishing gear and bite through bone.”

In addition to powerful jaws, the bodies of silver-cheeked pufferfish contain the deadly toxin tetrodotoxin, which can cause paralysis and respiratory failure.… pic.twitter.com/PCGNuxxdtw

The fish reportedly does not tend to attack people unless one tries to touch it.

“A 2024 study published in the peer-reviewed journal Toxics documented 198 human-health incidents involving invasive puffer fish across the eastern Mediterranean between 2004 and 2023.
There were 28 records of physical attacks, at least 144 non-lethal poisoning episodes and 27 human fatalities resulting from consumption of the fish, the study found.”
Greek authorities have gone as far as setting up floating barriers to safeguard people in the water.
