http://en.wikipedia.org/wiki/Woodlouse A woodlouse is a crustacean with a rigid‚ segmented‚ long exoskeleton and fourteen jointed limbs. Woodlice form the suborderOniscidea within the order Isopoda‚ with over 3‚000 known species. The woodlouse has a shell-like exoskeleton‚ which it must progressively shed as it grows. The moult takes place in two stages; the back half is lost first‚ followed two or three days later by the front. This method of moulting is different from that of most arthropods

Report on the distribution of slaters in different level of soil pH Introduction Slater (woodlouse)‚ Biological name Porcellio scaber‚ is probably the most common species in New Zealand. They belong to the biological class Crustacea. Their size is about 17mm in length. They have rough exoskeleton and usually in dark grey colour. They have 7 pairs of legs‚ each pair is attached to the underneath of each thorax segment. Their body consists into three sections: head‚ thorax and abdomen‚ these are

Erin Annabell INTRODUCTION The ecological niche of the Porcellio scaber: The Slater belongs to the biological class Crustacea. The slaters studied were found in damp‚ cool‚ humid conditions. They are most easily found in spring and autumn. The most common site around the home is on compost heaps or under shelter such as bark‚ wood piles and boards left in shaded‚ moist conditions. They may also be found in deep‚ damp soil litter under the shelter of bushes or trees. So that they were not exposed

Contrary to their name‚ sowbugs (Porcellio laevis) are tiny crustaceans that live in moist environments around the world. These creatures‚ about 12.5 mm in length‚ are extremely unique in their physiology‚ habitat‚ diet‚ and behavior. Sowbugs are harmless to humans‚ but incredibly important to ecosystems. They are found easily in nature‚ and are quite hardy (Franklin‚ Julie A.) Though they use gill-like structures‚ called pseudo tracheae‚ to breathe‚ sowbugs cannot breathe underwater but are highly

Pill bugs are knows as woodlice‚sowbugs‚ and roly-polies.Despite the name Pill bugs aren’t actually “bugs” they are classified as terrestrial isopods and fall under the class Crustacea.This class also falls under an even larger group called Arthropoda. Arthropoda consists of many Arthropods that have bilateral symmetry‚segmented bodies‚exoskeletons‚jointed appendages‚and numerous pairs of limbs.Pill bugs also have a flattened or round-backed profile‚seven pairs of legs‚ and sharply-angled antennae

Food Preferences in the Sow Bug (Porcellio Laevis) Purpose The purpose of this experiment is to determine what kind of food the sow bug prefers; decaying leaves‚ potatoes‚ grapes‚ or sow bug food. Hypothesis If a sow bug is placed in a choice tray‚ and has access to decaying leaves‚ potatoes‚ grapes‚ and sow bug food‚ the sow bug will choose the decaying leaves over its other options. This hypothesis was based on research stating that a sow bug’s main food source is decaying vegetation. This
