Often mistaken for beetles, these live terrestrial arthropods live their whole lives on land, feeding on decaying organic matter.
When disturbed or threatened, pill bugs will roll up into a tight ball, earning them the nickname "rollie pollies."
Contrary to pill bugs, sow bugs can be identified by their tail-like appendages and will remain flat and still when threatened, unable to roll up into a ball.
Ideal for teaching animal behavior and demonstrating response to stimuli such as light or heat, these wingless crustaceans are:
- Easy to maintain in the classroom
- Do not bite or sting
- Demonstrate differences in defensive behavior between species
