• Resumen

  • Pain looks at the techniques used by David Dunstan, Ruth Brooks, and Dave Hodgson to track snails in their garden. Impressed by the sophistication of snail behavior, Hodgson did some snail-tracking of his own. To check what they were up to after dark, he attached colored LED "disco" lights to some and painted others with glow-in-the-dark UV paint. Time-lapse photography revealed that snails move faster and further than most imagine, reaching speeds of 1 meter an hour and able to cover 10 meters a night. In wet weather, they form convoys, sliding along the slime trails of preceding snails, which Hodgson suspects helps them save energy.
