Woodlice, Crustaceans

Woodlice are crustaceans and fall into the order Isopoda. They are predominantly vegetarian, eating mainly decomposing plant matter. They have seven pairs of legs and external 'book-lungs' which makes them vulnerable to drying out, hence they are nocturnal and hide in damp places during the day. There are 37 known species in the UK, some of which are very common and familiar. Six species in particular (the big 6) are found just about everywhere and are probably in your garden (if you have one).

Other UK non-marine crustaceans include Crayfish and an array of mainly small aquatic species.
