"Sow Bug vs. Pill Bug"
Sow Bug vs. Pill Bug Isopods are related to Crustatians Isopod, Pillbug, Sow Bug Information Feeding Isopods demonstrate nearly all of the possible feeding habits used by crustaceans. Some are scavengers feeding on dead fish by stripping the carcass of its flesh within hours. Others are permanently parasitic on live fish by burrowing into the flesh, attaching to the gills or living inside the mouth. Burrowers with strong jaws chew through wood and are able to digest cellulose using the bacteria in their gut. Herbivores graze on seaweed remaining camouflaged to the colour of the algae in which they hide. Some isopods are predators capturing their prey with their first legs. Habitat/ Distribution The many thousands of species of isopods are classified in about 95 families. Greatest diversity is seen in the deep parts of the ocean basins at 1000- 5000 metres depth. The most familiar isopods of all are the fully terrestrial sow bugs and pill bugs found in gardens and all other land habitats. Classroom habitat. Isopods are Isopods excellent classroom animals—they exhibit interesting behaviors, they are small but not tiny, they don’t bite, fly, or jump, and they are easy to care for. Isopods can live in just about any vessel, from a recycled margarine tub to a 50-liter aquarium. If the container is smooth-sided, it doesn’t even have to be covered, because isopods can’t climb smooth surfaces at all. The most important thing to remember is that the soil must be kept moist at all times—not wet, but moist—so that the isopods don’t dry out. • Form Hypothesis Lab Process • Narrow your question down to one question that can be tested • Consider how you will collect data (How will you measure your results?) • Design experiment • Make a list of equipment you will need • Consider uncontrolled variables, adjust if necessary, list most important that you could not test for. • Best ethics: Do not design experiments that will destroy animals
