Woodlouse Identification

We've found lots of woodlice under logs and in leaf litter at Sydenham Hill Wood recently including the common shiny, the common striped and even what we believe to be pygmy woodlice :O Woodlice are not actually insects but in fact crustaceans and are related to shrimps and crabs! They play an important part in the nutrient-recycling system and eat leaves, rotting wood and even their own faeces but they don't pee, instead they release ammonia as a gas through their shells
