The invasive lionfish has officially arrived in Maltese waters, ending years of speculation over whether the striking but destructive species had reached the islands.

Marine biologist Professor Alan Deidun confirmed that a Devil firefish (Pterois miles), one of the two species commonly known as lionfish, has been caught and photographed locally. The discovery represents the first verified record of the species in Malta.

The specimen was caught by James Mamo, whose find provides the photographic and physical evidence researchers have been waiting for.

According to Deidun, reports of lionfish sightings have surfaced on several occasions over the years, but none were supported by evidence that could officially confirm the species' presence.

"Numerous claims had been made about lionfish in Maltese waters, but until now there was no proof to substantiate those reports," he explained.

The lionfish is regarded as one of the world's most problematic invasive marine species. Originally from the Indo-Pacific, it has expanded rapidly throughout the Mediterranean, threatening native biodiversity wherever it becomes established.

Its success is largely due to the absence of natural predators in the regions it invades. An aggressive predator, the lionfish feeds on a wide range of small fish and crustaceans, placing additional pressure on native marine life and upsetting the balance of local ecosystems.

Despite its attractive appearance, the lionfish should not be handled. Its distinctive fin spines contain venom capable of causing extremely painful stings, swelling and other severe reactions. Although encounters are rarely life-threatening, swimmers, divers and fishermen are advised to exercise caution if they come across one.

Scientists will now be watching closely to determine whether this is an isolated occurrence or the first sign of an established lionfish population developing in Maltese waters.
