They feed on lettuce and can crawl round a tank. This video shows a snail in in its tank. The video is taken at 1 frame every 50 seconds and lasts for 13 frames, so I hope its short enough for you to have a look! During this time it crawls across the face of the tank and round the side.
You can look at the analysis software Julian Derry and I have devised to report the 3-d position of the snail in the tank. A sample frame analysis is hown here .
