Ash-Black Slug

Fascinating facts about the Ash-Black Slug

• The ash-black slug holds the title of the world's biggest land slug, a distinction that comes from its extraordinary length. Individuals can grow to over 30 cm, dwarfing most other terrestrial slugs. Most adults, however, fall in the 10-20 cm range, showing considerable size variation within the species. Its sheer size makes it a true giant among land molluscs.
• Some ash-black slugs exceed 30 cm in length, a remarkable size for a mollusc, while the majority of adults measure between 10 cm and 20 cm. Juvenile individuals start out ash-gray with a toffee-brown hue before maturing. Adult slugs display a wide palette of colours - from jet black to pale gray and medium brown - and bear a distinctive white-to-pale-tan stripe along their long, prominent keel.
• The ash-black slug's range pushes eastward to the Ural Mountains, marking the farthest known point of its distribution. It is native to Europe and recorded in most European nations, including Bulgaria, the Czech Republic, Italy, the Netherlands, Slovakia, Ireland, Great Britain, Finland and Ukraine. The slug is common across much of this area but becomes rare or absent in the southernmost parts of Europe.
• Although the species occurs on the Iberian Peninsula and the Balkans, no records exist from Portugal or Greece. It is native to Europe and has been recorded in most European nations, such as Bulgaria, the Czech Republic, Italy, the Netherlands, Slovakia, Ireland, Great Britain, Finland and Ukraine. The slug's range even reaches eastward to the Urals, but it becomes rare or absent in the southernmost parts of the continent.
• The ash-black slug inhabits ancient woodlands and sometimes parks, taking refuge under dead leaves and fallen logs. Within these habitats it lives beneath leaf litter and timber, where it can remain concealed. Its diet consists mainly of mushrooms and algae, allowing it to thrive without becoming a pest to human activities. This combination of shelter and food sources supports its presence in these natural settings.
