Species description
Geographical Origin and Habitat: Originally native to Europe, now widely established globally due to human activity. Inhabits temperate forests, gardens, and urban organic debris, sheltering under rotting logs, stones, and leaf litter to prevent dehydration.
Taxonomy and Genetics: Features a flattened, oval body with a rough, tuberculated cuticle, reaching up to 1.8 cm in length. Capable of rapid movement rather than rolling into a tight ball. The Orange morph is selectively bred to express a bright, solid orange or rust-colored exoskeleton.
Behavior and Habits: Strictly nocturnal and lucifugous (hiding from light). They are highly gregarious detritivores, often clustering in large numbers in damp, dark crevices. In enclosures, they actively consume organic debris, leaf litter, and mold.
Morphology: Males and females are externally similar. However, adult females can be identified by the presence of a ventral brood pouch (marsupium) where they carry eggs and developing young (mancae).
Care, breeding and tankmates
Terrarium Setup: Can be easily cultured in a ventilated plastic box (minimum 5 liters). Substrate should consist of 5-10 cm of organic compost or coco fiber mixed with rotting wood and crushed leaves, topped with cork bark slabs for cover.
Lighting and Heating: Keep in a shaded or dark location. Maintain temperatures between 20°C and 25°C for optimal reproduction. They do not require any special lighting and should be kept away from direct sunlight.
Humidity and Hydration: As terrestrial crustaceans, they breathe through modified gills and require constant ambient moisture. Maintain a moisture gradient by keeping one side of the substrate damp while leaving the other side dry.
Feeding and Supplementation: Diet must consist primarily of decaying deciduous leaves (oak, beech) and rotting wood. Supplement twice a week with protein sources (fish flakes, dried shrimp) and fresh vegetables. Provide a constant source of calcium, such as cuttlebone, for exoskeleton development.
Compatibility: Safe and effective clean-up crew for many reptiles, amphibians, and invertebrates. Avoid using them in enclosures housing tiny hatchlings or delicate eggs, as they may accidentally nibble on them in search of protein.
Health and Common Diseases: Vulnerable to desiccation if the enclosure dries out completely, and to drowning if the substrate becomes waterlogged. Ensure proper cross-ventilation to prevent stagnant air and mold overgrowth.

The catalog's scalar value is 1.7 cm. The British Myriapod and Isopod Group — Porcellio scaber source reports a maximum adult measurement of 1.7 cm for this species, recorded as body length. The biological datum refers to the base species Porcellio scaber, not exclusively to the commercial variety. These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
