As part of ongoing research into the transmission of lungworm from snails to dogs, a team of researchers from the Ecology department at the University of Exeter lead by Dr. Dave Hodgson created an experiment to track the movement of snails through a garden at night.
The team tagged hundreds of live snails with an array of LEDs and UV paint and then tracked their speed and patterns of movement at night. Apparently lungworm infections are potentially fatal in dogs and nobody is exactly sure how the organisms make the leap from snails to dogs in the first place, though the assumption is accidental ingestion.
If you want to skip the research story, and jump straight to the snail, which glows in the dark, start the video around 2:15.
