Watch out! Marine biologist issues warning about toxic alien fish spotted in Maltese waters
Local marine biologist Prof. Alan Deidun has issued a fresh warning to the public about a venomous alien species that continues to spread in Maltese waters – the silver-cheeked toadfish (Lagocephalus sceleratus).
In a recent Facebook post, Prof. Deidun explains that this invasive fish, which was first spotted in Malta back in 2015, has been sighted more frequently in local waters. He is currently investigating the species’ behaviour and diet, and he’s calling on the public to help monitor its spread.
‘This is a highly venomous species that has established itself in our seas,’ Prof. Deidun wrote. ‘It has fused upper teeth and should not be confused with the rabbitfish (Fenek in Maltese), which has long been caught locally and is far less dangerous.’
The silver-cheeked toadfish carries a potent neurotoxin called tetrodotoxin, which can be fatal if ingested. For this reason, the public is strongly advised never to eat or handle the fish, even if it appears dead.
If you spot this fish while fishing, diving, or swimming, Prof. Deidun is asking you to get in touch with him directly as part of the ongoing ‘Spot the Alien Fish’ citizen science campaign.
Photos of recent sightings are already being shared with Prof. Deidun as he tracks the species’ spread and impact on native marine life.
This is not the first time Maltese seas have faced the arrival of alien species, but the silver-cheeked toadfish is particularly concerning due to its toxicity and growing presence in the Mediterranean.
If you're out enjoying Malta's coastline or underwater scenery, keep your eyes open, and be sure to report any unusual fish sightings to support this important research effort.
Have you ever seen one IRL?
