Animals such as woodlice maintain the water balance of their bodies using behavioural adaptations. A behavioural adaptation is an action an animal takes that increases its chances of survival. Woodlice move faster in dry areas, and more slowly in humid environments.

How do woodlice defend themselves?
Woodlouse has segmented body and 14 legs. Some species, known as roly-poly or pill woodlouse, are able to curl their body into a ball to protect themselves against predators. Woodlouse has one pair of antennas on top of the head. They function as sensory organs which facilitate navigation in the space.
What do woodlice need to survive?
While most crustaceans live in water, woodlice live on land but breathe through gills like fish. Their gills need to be covered with a thin layer of water to work well, so they prefer to live in places with a lot of moisture. These creatures are found in cool, damp areas, such as under fallen leaves in flowerbeds.
Can woodlice breathe underwater?
Woodlice, also known as armadillo bugs, cheeselogs and pill bugs, are not insects but crustaceans. They breathe through gills which are attached to the swimming legs on their abdomen; moist tubes extract oxygen from the air but if submerged in water they can survive for about an hour.
Why do woodlice lose water easily?
INTRODUCTION Woodlice lose water rather rapidly by transpiration into unsaturated air (Edney, 1951). ... It is clear that woodlice absorb water when eating moist food, but partially desiccated animals, left in the presence of potato dice, regain their original weight even when the food is uneaten.
Can a woodlouse turn over?
Spend a quiet two minutes watching a woodlouse (aka pill bug, roly poly, cheeselog, armadillo bug, boat builder, slater, sow bug, roll up bug…) flip over from its back. Known for curling up into a protective ball, this “bug” has a lot of regional nicknames, but is it actually a bug?
Why do woodlice curl up in a ball?
The pill woodlouse is rounded and slate grey, and when it is disturbed, it rolls up into a ball (resembling a small pill) to protect itself. It feeds on dead and decaying matter and is an important nutrient-recycler.
Do woodlice drink water?
How do you let the woodlice drink? Woodlice, like many other insects, get their water from their food. Consider spraying them with water to add moisture. ... They're bugs, they don't eat much.
Do woodlice breathe through gills?
Most woodlice are found on land, but their ancestors used to live in water and woodlice still breathe using gills.
How do you know if a woodlouse is a boy or a girl?
It's surprisingly easy to work out their gender – the males have a “genital projection” aka willy (cue giggles from kids) that extends along the middle of their abdomen. The females have marsupium, brood pouches, where they place fertilised eggs to safely incubate.
Can woodlice bite?
Warm and damp habitats with plenty of crevices are favourites, including rotting wood, brick walls and even cellars. This spider's jaws are strong enough to give humans a painful nip if handled.
Do woodlice have eyes?
Woodlouse senses are centred around the jointed antennae and simple eyes that have only about 25 individual ocelli – probably enough to detect light and shade and largish moving objects, but probably incapable of forming images with a very high degree of resolution.
What do woodlice eat and drink?
As well as decaying wood, common rough woodlice feed on leaf litter, fungi, fallen fruit, dead animals and even faeces. They even eat their own excrement, an act known as coprophagy. The species does this to recycle copper in their diet as their blood is copper-based like marine crustaceans.
Do woodlice prefer dark or light?
In their natural environment, woodlice are found in damp, dark places (e.g. under stones and amongst rotting wood/leaf litter). They dry out quickly in dry air (e.g. in the open and/or in bright sunlight). ... For example, woodlice are more active in dry conditions and less active in damp conditions.
When did woodlice evolve?
Ancestral trilobite fossils date from the Eocene period 50 million years ago, but the existence of some 3,500 species worldwide suggests that they were present before the continents drifted apart 110 million years earlier.
How do woodlice detect moisture?
Partially desiccated woodlice can also be observed to take up water from droplets or from wet filter-paper by immersion of either the mouthparts or the terminal appendages (uropods).
