pillbug: Effect of stimuli on pillbugs
Description
An experiment on the effect of different stimuli was carried out with 60
pillbugs. The bugs were split into three
groups: 20 bugs were exposed to strong light, 20 bugs were exposed to
moisture, and 20 bugs were used as controls. For each bug it was registered how
many seconds it used to move six inches.source
