#12). Isopods‚ otherwise known as pill bugs‚ are scavengers that feed on dead and decaying plants and animals. Pill bugs vary in color from dark grey to dark brown and are easily recognized by their oval‚ segmented bodies. They are the only crustaceans that have adapted to living their entire life on land (Potter). However‚ pill bugs still breathe through gills; therefore‚ they are restricted to live in environments with high humidity ("Isopod‚ Pillbug‚ Sow Bug Information”). Isopods tend to remain

Problem: Do Pill bugs prefer being in an environment with tight spaces‚ or a more open environment? Hypothesis: If the pill bugs are given a choice of an open environment or one with tight spaces‚ then the pill bugs will respond by going to the environment with tight spaces. Brief Methods We used a Petri dish with 2 circle‚ and an opening connecting the two. We put 10 Pill Bugs in the opening between the two circles‚ and timed them for one minute. This gave them time to choose dish 1 or dish

Pill Bugs Turn Alternation Lab Report Bio Lab 111 Nov. 15‚ 2012 Pill bugs are said to have some sort of turn alternation built in there cognitive functions‚ which causes them to take a zig-zag route rather than going along in a straight line for a long distance (Ono Tomohiro & Takagi Yuika‚ 2006). Distance does not play a factor in the pill bugs making turn alternation even if it is a forced turn‚ pill bugs will still make a zig-zag motion (Kupfermann‚ 1966). The zig-zag motion shows that

to environmental factors? For example‚ a chameleon will change colors to hide from predators. Bears hibernate in the winter to conserve energy because of the food shortages. Likewise‚ pill bugs avoid light and try to make homes in dark‚ damp environments and eat decaying plant and animal matter. The reason pill bugs prefer dark and damp environments is because they behave negatively to phototaxis‚ which is the response to light‚ and have a partially positive behavior towards hydrotaxis‚ which is the

Movement of Pill Bugs? Purpose: The purpose of this lab was to analyze pill bug’s activity in different environments and determine the effect of wet/dry or dark/light environments have on them and how taxis takes place in their choices in living in areas. Background information: Terrestrial isopods are commonly referred to as sow bugs and pill bugs and have other nick names as well. These pill bugs are also related to lobsters‚ crabs and shrimp making them breathe with gills. Pill bugs also tend

Science Observation Results Essay (Living Organism) For this project I had observed the coolest bug balls on earth‚ the roly- poly. They are commonly known as the roly-poly‚ also pill bug‚ and wood lice. Its scientific name is Armadilidum vulgare. It is actually not an insect‚ it is an isopod ( a type of arthropod). It’s genus is Armadilidum‚ it’s Phylum is Arthopoda‚ and Subphylum is Crustacea. I have observed that the exoskeleton is a blue-gray‚ it is an invertebrate‚ it’s mouth‚ 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

lab felt very “slow” because there was not a lot of action going on. The pill bugs would either walk around in circles or stay put. However‚ it was both fun and annoying when my group tried to put the pill bugs in the chamber and take them out. We had to put a lot of effort to get the pill bugs on to the paint brushes because they would scurry around and it would take a while to find them. Also‚ it was cool to see the pill bugs use their defense mechanism (it only happened once) by going into a hard
