| Research Abstract |
We investigated whether or not pill bugs were able to estimate cliff depth with reference to the length of their antennae. In order to investigate the factors influencing the decision to proceed or retreat when the cliff depth is almost the same as the distance that their antennae can reach, the length of the antennae was extended by attaching Teflon tubes to their tips. The results suggested that they climbed down the cliffs based on information about the length of the tubes. In the other situation, we investigated the time series of antennal touching time on the obstacles, which can be assumed to be related to searching of stimuli, by image processing technique. The result showed that pill bugs can actively search for stimuli anticipating their direction.
