A new study of UK snail behaviour using LED and UV light tracking has found that the nocturnal creatures can explore the length of an average British garden in just one night, reaching a top speed of 1mph (metre per hour).
The 'Slime Watch' report was commissioned by Bayer Animal Health, makers of Advocate, as part of its 'Be Lungworm Aware' campaign and led by Dr Dave Hodgson, Associate Professor of Ecology at the University of Exeter, who studied the habits of 450 garden snails, recording their movements using LED lights and UV paint. This is the first time snails have been studied in this way.
The study found that snails will travel distances of up to 25 metres in a 24-hour period, and seek out areas of shelter, such as long grass, trees or objects, including dogs' toys, left in the garden overnight. The four researchers from Exeter University also discovered that snails move in convoys, piggy-backing on the slime of other snails to conserve energy. It is thought that a snail could use up to 30 per cent of its energy in slime production alone.
Dr Hodgson said: "Until now no one has fully understood the habits of these fascinating creatures that we encounter in our gardens every day. In this research we wanted to solve the mystery surrounding gastropod activity and provide a resource for gardeners and pet owners wanting to better safeguard the health of their plants and pets. By learning more about the behaviour of snails, we hope dog owners can better understand they ways in which dogs can encounter snails on a day-to-day basis and the lungworm risk they present, taking the appropriate precautions."
