The rough surface and the the dark color distinguish it from Oniscus asellus , as does the apiculate middle lobe on the head. [from comment by Ferenc Vilisics] Densely covered with tubercles. Usually dark grey, sometimes quite red or variegated with yellow. Albinos have been reported.

About Isopods: the wider group

Order-level background for Isopoda, the group containing Porcellio scaber. Species-specific details appear above.

Group overview

Isopoda includes ~10,000 described species of woodlice, pill bugs, and sea slaters. Woodlice are the only crustaceans to have fully adapted to life on land. Pill bugs (roly-polies) can roll into a perfect ball for defense.

Ecological role of the group

Woodlice are critical soil decomposers, breaking down dead plant material and recycling calcium and other nutrients. They breathe through gill-like structures and require moist environments. Giant deep-sea isopods (Bathynomus) can grow up to 50cm long.

Economic and practical significance of the group

Woodlice are generally beneficial in gardens as decomposers, though they can occasionally damage seedlings and soft fruits in large numbers.

Recorded sources for this group: Soil ecology research, marine biology. Imported estimates may describe particular regions or reporting periods.
