There’s a relatively new reptile making appearances around Malta: the coin-marked snake, an exotic species that experts say may be showing signs of establishing itself locally. Herpetologist Nick Dobbs has renewed warnings after being sent a video of a 1.09-metre-long shed skin attributed to the snake found in Malta, further confirming that the species is now being spotted more frequently across the islands.

The situation first came to light in February 2025, when wildlife specialist Arnold Sciberras, known as The Exterminator, reported a noticeable rise in sightings since it was first spotted in 2022. Back then, there were seven confirmed sightings, occurring in the areas of Marsascala, Delimara and Marsaxlokk. One of these snakes was even unintentionally released after being mistaken for the native leopard snake.

The coin-marked snake (Hemorrhois nummifer), known in Maltese as lifgħa tal-lvant, is non-native and potentially invasive, meaning monitoring and early intervention are crucial to prevent it from establishing itself in the wild.

The species has a robust body that is typically brown, grey, or olive-grey on top with a grey-white belly. It features a dorsal row of about 57–65 large, distinct spots that can turn into a continuous line on the tail, and smaller spots along the sides. 

Here are some helpful tips if you come across a snake in the wild:

It closely resembles the native leopard snake.
Misidentification is extremely common, so experts are urging caution.

Don’t release it if found.
If you come across a snake that looks unfamiliar – especially one believed to be a leopard snake – don’t let it go immediately. Take clear photos and report the sighting.

Contain it if safely possible.
This helps specialists confirm the species and decide on the next steps.

Herpetologists are appealing to the public for their help, because if the coin-marked snake establishes a breeding population, it could disrupt local ecosystems and compete with Malta’s native wildlife. Nick Dobbs added that while the species is not overtly harmful to humans, it can demonstrate some aggressive behaviour, so make sure to keep a respectful distance at all times.

If you do happen to come across a snake that might be a coin-marked one, report any sightings to the Exterminator on the following numbers: 2143 6820 / 9988 7950 / 9911 3445, or visit The Exterminator Malta website for more information.

Experts emphasise that public awareness and proper documentation are key to preventing an invasive species issue from taking hold in Malta.
