A slug with a leopard pattern

Mauro’s photograph shows a slug with dark markings and extended tentacles on stone. The record, dated 17 September 2021, is identified as Limax maximus. Comparing the published point with CAOP2025 places it in Arco de Baúlhe e Vila Nune.

The Royal Horticultural Society includes this species in its comparison of large patterned slugs, noting its nocturnal behaviour. The local photograph records an encounter; it cannot predict when the animal will appear in the same place again. Its body pattern offers a good question to begin with: where do you see separate spots, and where do they seem to form lines?

Alongside the photograph of the Cavez snail, it offers two different ways to discover land molluscs: the spiral of a shell and the pattern of an elongated body.
