Living Things Lab
I am the science enrichment teacher for learning pods at the ColLab. After observing the skulls of deer and comparing pinecones and evergreen needles, we investigated roly polies. A preassessment provided insight into our background knowledge of pill bugs.
Facts We Learned:
Pill bugs, also called roly polies, potato bugs, and isopods, are not bugs at all, but crustaceans and therefore related to shrimp, lobsters, and crayfish. They are the only terrestrial crustacean.
Roly polies breath through gills and must consequently live in a damp habitat. They are more active at night.
When threatened, pill bugs roll into a ball. Armadillos use the same defense mechanism.
Pill bugs have 14 legs (seven pairs).
They grow by molting a hard exoskeleton.
As decomposers, they eat rotting vegetation on the woodland floor.
Eggs are carried in a pouch under the female.
