Apologies for poor quality photos. Several of these creatures sprang around energetically when the stone they were hiding under was lifted, some jumping several inches into the air. The stone was on damp soil beside a section of canal with a muddy bank (no concrete wall). This one curled up when it began to dry out then uncurled and became lively again when a few drops of water were dripped onto it. (It was put back where it came from after being photographed.)
